MICROCON® Mobile Health Care Air Purification Systems (Healthcare) and
Mobile Hospital Air Purification Systems
Located in Eatontown, NJ.

Biological Controls, is acknowledged as one of the foremost companies providing products for health care (healthcare) and related contamination control applications. Biological Controls celebrates 32 years of serving organizations such as hospitals, health care (healthcare) facilities, pharmaceutical companies, research labs, electronic component manufacturers, and military and government agencies with high-performance air purification systems.

TB was on the rise in the early 90’s and Biological Controls was approached in 1992, by a group of NYC hospital facilities managers who were in desperate need of a mobile hospital air purification system to eliminate infectious airborne pathogens during the treatment procedures, of diagnosed or suspected TB Tuberculosis patients and protect the physicians and staff.

Biological Controls, then began designing and building equipment specifically for airborne infection control applications. Biological Controls introduced the MICROCON® 800 Mobile Hospital Air Purification System, primarily for use in hospitals, medical clinics and health care (healthcare) facilities. By introducing the MICROCON ® 800 the hospitals now had a portable and mobile purification unit, they could position for either spot or permanent applications.

MICROCON® was designed in a modular component configuration to allow for the greatest flexibility of customization. The MICROCON® remains the mainstay of Biological Controls’ product line. The MICROCON® mobile hospital air purification system does not restrict room use, since it's not a permanent installation, allowing flexibility in planning patient load or room utilization.

MICROCON® 800/400 Mobile hospital air purification systems are high-capacity air purifiers specifically designed to remove hazardous microbial airborne particulate. They work by eliminating sub micron-size infectious airborne particles from established breathing zone areas, reducing airborne microbial migration and the risk of inhalation. The product quickly became the market leader in medical facilities air purification systems and health care air purification systems utilizing a HEPA filtration system, thereby reducing risk of airborne infection by removing airborne pathogens that are contained in airborne diseases.

The mobile hospital air purification system can be placed beside patients in isolation rooms and other critical areas of use, including admittance, waiting and emergency rooms.The best results are achieved when the MICROCON® air purifier is placed closest to the source of the contamination. (This is called source or control capture.) Capturing airborne contaminants at the source, eliminates contaminant migration further reducing airborne infection transmittal.

CDC Guidelines recognize that a hospital air purification system and HEPA filtration system can play an important part in airborne infection control of TB. Our entire line of products use HEPA filters as a primary means of airborne infectious bacteria capture.

The HEPA filter is the heart of the MICROCON® mobile air purifier, the same well-established and proven HEPA filtration system and technology that is used and embraced by high tech and medical establishments. When we combined the HEPA filtration system with germicidal UV lamps (UVGI), which also have a long and established track record, we produced an mobile hospital air purifier that was immediately embraced by the Health Care (healthcare) community for protection against airborne pathogens. The MICROCON® 800/400 Mobile Hospital Air Purification System proved to be an immediate success.

The MICROCON® 800/400 was the first mobile hospital air purifier to address the safety concerns of health care (healthcare) workers. The location and process of air intake and exhaust is critical to the HEPA filter’s functionality and unique level of performance. Design of a health care air purification system was needed to take into consideration the medical staff and caregivers working where the risk and exposure to airborne pathogens is the greatest.

From the original MICROCON® 800/400 hospital air purifier concept, a full range of other products bearing the MICROCON® label have been introduced over the last 10-12 years. All our filter units are certified as meeting CDC Guidelines, and carry a FDA 510K certification that exceed requirements in every case.

Clean air purification systems, particularly those using mobile clean air purifiers for airborne infection control in hospitals and health care (healthcare) facilities (and other air purification systems in general), are vitally important in the control of airborne diseases and airborne infections, especially for drug resistant strains.

The importance of rigorous performance recommendations was established and led the CDC (Center for Disease Control) to institute guidelines for controlling TB infection in hospitals, health care (healthcare) and medical facilities. The CDC guidelines are enforced now by some agencies concerned with patient and employee health, including OSHA and JCAHO. JCAHO has incorporated the CDC guidelines into their evaluation process and evaluates compliance as part of the certification process.

Biological Controls offers a wide array of hospital air purification systems, health care air purification systems (healthcare) air cleaners and other products designed to:

• Reduce risks of disease transmission
• Provide compliance with all regulations
• Provide flexible use in various applications
• Eliminate the need for expensive renovations to HVAC systems

Biological Controls products are used effectively in removal of airborne pathogens, creation of negative pressure, monitoring of pressure differential conditions and enclosures for use in performing high risk procedures or holding patients who are known or suspected to be at risk of transmitting airborne diseases and airborne infections.

Assurance of Quality Performance

Rigorous testing of equipment for hospital air purification systems and air cleaning is critical, since one cannot tell by sight if it is performing properly and the particles are being removed or the pressure differential is being maintained. Biological Controls’ products have been tested extensively to assure their efficacy and high level of effectiveness. Our products are designed with visible controls and gauges to aid in monitoring performance.

Each product is designed to perform a specific function in meeting the CDC guidelines and engineering controls. They integrate to form a hospital air purification system and health care air
purification systems (healthcare) that provides an inexpensive yet superior performing alternative to standard engineering retrofits. Independent documentation confirms the efficacy of the design of Biological Controls’ products.

HEPA filters by design are resistant to the passage of air. Therefore, proper sealing of HEPA filters is essential to maintaining the integrity of the system. Any bypass of unfiltered air compromises the system. The CDC Guidelines address the need for adequate sealing in health care air purification systems (healthcare). Also a means of assessing the loading of the HEPA filter, is necessary. Biological Controls’ products are all equipped with a minihelic gauge (a pressure differential gauge designed to monitor filter life expectancy). As the filter becomes clogged with contaminants (thereby increasing resistance) the less filtered air is delivered at rated flow. HEPA filters don’t become less efficient with use only their airflow delivery diminishes with use. The pressure reading on the gauge is an objective means to determine the filter loading and degree of resistance on the system. It is a much more accurate means than the more commonly used, less costly and less accurate filter warning light.

HEPA Filtration Hospital Air Purification Systems and TB

TB is a highly infectious disease that requires removal of contaminants from the air to prevent airborne transmission of the disease There are two forms of TB: Type M tuberculosis: latent infection and active infection. In mycobacterium tubercle bacteria/Type M (mycobacterium) tuberculosis, only an individual with active TB of the lungs or airways can spread the disease by coughing and sneezing. Transmission is most likely to occur when individuals are in close proximity for extended periods of time.

Most office settings and worksites do not involve the sustained close contact needed to spread the infection. Many of the current cases of TB (Type M tuberculosis) are found in those workplaces that bring people into close contact with others who have active TB Type M tuberculosis, such as health care (healthcare) facilities, correctional institutions, and shelters for the homeless.

Some people with immune deficiency may be at a higher risk of contracting TB (tuberculosis). Those with a significantly suppressed immune system (due to poor health, chronic abuse of alcohol or drugs, old age, chemotherapy for cancer, or HIV infection - human immunodeficiency virus, the virus that leads to AIDS - are more likely than a healthy person to develop active TB disease if they already have latent TB infection or are exposed to a new TB infection. The risk of developing active TB in an individual who has latent TB infection but has an intact immune system is very low (10 percent over a lifetime). However, the risk of developing active TB for an individual with both human immunodeficiency virus (HIV) and latent TB infection is much greater (8 percent per year).

High-Performance Mobile Hospital Air Purification Systems by Biological Controls

The MICROCON® Mobile Hospital Air Purification Systems product line provides airborne
infection control and protection throughout thousands of hospitals, medical, and healthcare facilities (helathcare) and clinics across the US and worldwide. Air purification designed in every configuration, air pressure monitoring and creation of isolation rooms and enclosures are just some of the products we offer.

Our air cleaners create a clean, safe environment by clearing particulates, infectious air, and VOCs (volatile organic compounds) from the air. All MICROCON® Mobile Hospital air purification systems and related products are available through our online catalog. They can be adapted for a wide variety of applications and units can be ceiling mounted, wall mounted or portable. Read on to learn more about the superior features of our air purification systems.

Breathing Zone Filtration and Mobile Hospital Air Purification System

The most critical area is your “breathing zone”, the precise area that contains the air you breathe given your position. It can extend from 3 to 7 feet from floor level and it changes when you sit, stand or lie down. Any hazardous airborne particulate suspended within this zone can be hazardous to your health. Potential hazardous bacteria introduced into the air by infected patients or through ventilation systems range in size from .03 to 5.0 microns. They are invisible to the naked eye and can remain suspended in the air stream indefinitely.

Our “breathing zone” design is based upon the source or control capture concept. The CDC states, "Source control techniques can prevent or reduce the spread of infectious droplet nuclei into the general air circulation by entrapping infectious droplet nuclei as they are being emitted by the patient (i.e. source).” MICROCON® hospital air purification products are designed for source control of these particulates within the “breathing zone”.

Independent hospital testing of the MICROCON® Hospital Air Purification System and Mobile Air Purification System has shown that Biological Controls' 360 degree intake and exhaust airflow pattern dramatically reduces particulate levels and maintains virtual zero levels within the “breathing zone” as long as the unit is operating.

The MICROCON® air purification series creates a CIRCUMFLOW® air pattern within a room. The MICROCON® air purifier intakes air within the “breathing zone” for source or control capture, and exhausts filtered air at floor level. This sends out a steady air stream that creates air currents and patterns within a room at all levels. Suspended airborne particulate is pulled into the unit and extracted from the “breathing zone”. The HEPA filtered exhaust air dilutes and pushes remaining air back into the area where it's collected.

No other units on the market replicate this unique feature as it’s a patented process which has been documented and confirmed to greatly improve the “breathing zone” filtration within a room. Two models are available: the MICROCON® 800 and 400, both meeting the CDC requirements for HEPA Filtration and exceeding recommendations for room air changes per hour (ACH). MICROCON® mobile hospital air purifier systems delivers 2 to 5 times the recommended 12 ACH per hour.

MICROCON® is known as "the only mobile hospital air purification system patented for removal of airborne contaminants in Health Care (Healthcare) settings." Units by other manufacturers with unidirectional airflow, one-side intake or one-side exhaust, particularly where air intakes are located at the floor level, can be ineffective or take much longer to capture contaminated particles. These units’ performance worsens when their exhaust blasts air out, usually from the top, scattering airborne particulate all over the room. Since there is no consistency to creating the airflow patterns these units can produce, erratic air mixing leaves stale and stagnant air pockets within a room.The CIRCUMFLOW® pattern is critical, because respirable particles in the submicron size range, such as the Mycobacterium tubercle bacteria, will float around the room, as will those particles just over a micron in size, such as droplet nuclei. They are propelled by air currents in the room and will not fall to the floor. They are light enough to float for weeks or months with no air currents, so they will remain suspended indefinitely when air currents are present, unless there is a means of removal.

Omnidirectional Unidirectional Airflow

The CDC Guidelines for TB Control address the need for dilution of airborne bacteria in rooms occupied by patients with known or suspected TB infection. Dilution is a key engineering control in prevention of the spread of TB.

The CDC explains that room air must be kept moving throughout all areas of the room to achieve the necessary dilution. The CDC guidelines discuss the need to test rooms and visualize air movement with smoke sticks, since we can't see the bacteria in the air or the dilution occurring. Corrective actions should be taken if there is a lack of air movement anywhere in the room.

The CDC allows for the use of portable, mobile hospital air purifier and HEPA filtration systems to help achieve the dilution of airborne bacteria needed in a room. Click here to learn why and to see drawings that show what happens: MICROCON®'s Omnidirectional Unidirectional Airflow. (Use your browser’s back button to return to this page and continue reading.)

Four 254 nm (nanometer) UV lamps provide Germicidal Ultra Violet radiation .The 254 nm wavelength has proven effective in killing most types of airborne bacteria and viruses. Coupled with a high efficiency HEPA filter cell, the germicidal effectiveness of the UV lamps is greatly enhanced. Four UV lamps are optional on both MICROCON® 800 and 400. Lamp life expectancy is rated at 6000 hours. Positioned downstream of the HEPA Filters, they are fully shielded, eliminating the maintenance requirements that other units on the market require when UV bulbs are directly in the effectiveness. An electronic sensor bar continually monitors bulb malfunction, and an hour meter registers system operation time.

Filter Replacement Capabilities

The MICROCON® series of mobile hospital air purification products uses a built-in minihelic gauge to measure air filter performance resistance, thereby monitoring filter replacement requirements. Some units on the market use no gauge whatsoever, while others simply rely on a non-objective "idiot" light to determine filter performance.

Our systems lend themselves to "bag out" filter removal procedures, which eliminate personnel exposure to contaminated filters.Most hospital and health care air purification systems on the market allow
direct exposure to contaminated filters, increasing the risk of exposure to staff. These less-safe systems require compression of rubber gaskets to assure proper filter sealing integrity. As the MICROCON® 800/400 mobile hospital air purifier is a modular self contained filter housing, sealing integrity is assured and capture containment exposure is eliminated.

Negative Pressure Hospital Isolation Rooms and Environments for Infection Control

The CDC recommends negative pressure isolation rooms for airborne infectious diseases. Specifically for patients with known or suspected infectious diseases such as Type M (Mycobacterium) tuberculosis, the Varicella-zoster virus (VZW or varibla major), Aspergillosis, the measles virus (rubeola), the smallpox virus (variola major), SARS and biological contaminants.

The recommendations for negative pressure isolation rooms also apply to areas where certain procedures are performed, including bronchoscopy, endotracheal intubation and suctioning, open abscess irrigation, and autopsy. Also, sputum induction and aerosol treatments that induce coughing may also increase the potential for transmission of M. tuberculosis. Monitor negative pressure isolation rooms settings by utilizing our ACCUSTAT® Portable Monitor. See product in our Online Catalog.

Negative Pressure Rooms, Negative Pressure Isolation Rooms, and Negative Pressure Hospital Isolation Rooms.

You’ll find there are many rooms in hospitals, health care (healthcare) facilities and other buildings that require or benefit significantly from maintaining negative or positive pressure.

MICROCON® CD-HUV (MCDHUV) with Germicidal UV HVAC Business Management Air Purification System and Health Care Air Purification System(s)

Recent biohazard and bioterrorism threats offer additional challenges to law enforcement and health care (healthcare) workers. The breadth of Biological Controls' product line provides many products that effectively address these issues.

The CDC recognizes UV Germicidal lamps like those utilized in the MICROCON® HUV products to irradiate Anthrax spores. Ultra violet (UV) lights and HEPA, or High Efficiency Particulate Arrestors, filters particles at a rate of 99.97% at 0.03 microns. As Anthrax spores are generally 1 to 5 microns, the HEPA filter systems in our air safety products removes the contaminated particles from the air, providing a safe breathing environment and reducing risk of infection.

Protection against particulate and gas phase pollutants is necessary for personnel in law enforcement and health care (healthcare) environments. The Center for Disease Control (CDC) recommends germicidal UV irradiation and HEPA filtration in all related applications.

The MICROCON® CD-HUV (MCDHUV) with Germicidal UV utilized in a Sherifs’ Offices Command Center as an application for clean air and gaseous odor removal An air purification system for such environments. It is a balanced combination of UV irradiation and HEPA filtration that activates carbon cells for gas phase pollutants. With a minimum efficiency level of 99.97% on particles 0.3 microns in diameter, HEPA filters effectively reduce Aspergillus spores (1.5 to 6 microns) to well below measurable levels.

UV has proven to be effective in reducing and eliminating microorganisms, bacteria, fungi, mold related to allergies, cold and flu viruses and most airborne infection and airborne transmitted diseases. In addition, carbon is recommended by the CDC for reducing and eliminating bioaerosols, VOC's (Volatile Organic Compounds) and other gas phase pollutants.

The MICROCON® CD Health Care Air Purification System. The CD is a ceiling-mounted three stage progressive health care air purification system and HEPA filtration system (healthcare) designed for
the removal of both airborne pollutants and gaseous contaminants from indoor environments. It is
comprised of a synthetic prefilter to contain large size airborne particles, a secondary hospital-grade
pleated filter cell removing 100% of airborne particles. The third stage for removal of gas
pollutants a unique carbon or charcoal composite cell is utilized which allows for higher absorbency
than comparable carbon cells.

It contains multidirectional exhaust louvers using the patented CIRCUMFLOW® Air Pattern. Air changes, filtration, dilution and gas phase contaminant removal with the MICROCON® CD will provide a much healthier environment.

OUR MISSION    

We believe, once you understand the new CDC guidelines, you’ll understand why our products offer you the best means of compliance. This is based upon a design philosophy that each piece of equipment is designed to satisfy a particular problem, and each problem can be satisfied by an individual or combination of products that complement each other.


CDC ON NEGATIVE PRESSURE

" To control the direction of airflow between the room and adjacent areas, thereby preventing
contaminated air from escaping from the room into other areas of the facility. The direction of air flow is controlled by creating a lower (negative) pressure in the area into which the flow of air is desired. For air to flow from one area to another, the air pressure in the two areas must be different. Air will flow from a higher pressure area to a lower pressure area. "

HOW BIOLOGICAL CONTROLS CREATES NEGATIVE PRESSURE 

Our MICROCON ® EX series, consisting of the EX-BB, EX-BUV, ExC-BB, and ExC-BUV, utilize HEPA filtration UV (option) for various room exhaust options. Wall, window or ceiling mounted, they direct air to either outside, back to return air system or corridor. Installation is quick, operation is economical, and maintenance is easy and safe. Monitor each room with the ACCUSTAT® pressure monitor by adjusting some models to automatically maintain exhaust requirements. The EX series is better suited than costly engineering controls.


CDC ON MONITORING NEGATIVE PRESSURE ROOMS

" Differential pressure-sensing devices can be used to monitor negative pressure; they can provide either periodic (noncontinuous) pressure measurements or continuous pressure monitoring. The continuous monitoring component may simply be a visible and/or audible warning signal that air pressure is low. In addition, it may also provide a pressure readout signal, which can be recorded for later verification or used to automatically adjust the facility's ventilation control system.”
" Pressure-sensing devices should incorporate an audible warning with a time delay to indicate that a door is open. When the door to the room is opened, the negative pressure will decrease. The time delayed signal should allow sufficient time for persons to enter or leave the room without activating the audible warning.”


HOW BIOLOGICAL CONTROLS MONITORS NEGATIVE PRESSURE ROOMS

The ACCUSTAT® was designed as a room pressure differential monitor that measures both posit ive and negative pressure. It will compare the room pressure to that of the corridor and maintain an accuracy of .001 inches WG (water gauge) as identified on a large digital readout. User set alarm function warns visually and/or audibly of a room not in compliance after a one minute "false alarm" cycle has been triggered. Has locking key switch controls for on/off and negative/positive selections. Remote monitoring capabilities are available, as well as interfacing with building management systems. Two models are available, a stationary mount and a rechargeable battery operated portable.

Rooms not maintaining proper pressure differentials can be equipped with MICROCON EX series units which enhance room exhaust between 100 and 450 CFM, thereby providing adequate pressure
differentials. Some units can also be tied to the ACCUSTAT®. If the room pressurization reaches the preset alarm setting, a signal from the ACCUSTAT® will increase the exhaust capacity of the exhaust unit. A five minute cycle repeats until the pressure condition is corrected. This is of critical importance since room pressure can vary throughout the day based upon HVAC and other operational factors.

CDC ON HEPA FILTRATION

HEPA filtration can be used as a method of air cleaning that supplements other recommended ventilation measures. HEPA filters are defined as air-cleaning devices that have a demonstrated and documented minimum removal efficiency of 99.97% of particles greater than or equal to 0.3 um in diameter. HEPA filters have shown to be effective in reducing the concentration of Aspergillus spores (which range in size from 1.5 um to 6 um) to below measurable levels (100- 02). The ability of HEPA filters to remove bacilli from the air has not been studied, however, M tuberculosis droplet nuclei probably range from 1 um to 5 um in diameter (i.e. approximately the same size as Aspergillus spores). Therefore, HEPA filters can be expected to remove infectious droplet nuclei from contaminated air. HEPA filters can be used to clean air before exhausting outside recirculated to other areas of the facility, or recirculated within a room.

WHAT BIOLOGICAL CONTROLS’ HEPA SYSTEMS DELIVER

CDC recognizes that HEPA filtration can play an important part in airborne TB controls. Our entire line of products utilizes HEPA filters as a primary means of airborne infectious bacteria capture. We provide certification and documentation on all our filter units. Our patented design of breathing zone filtration (BZF) and CIRCUMFLOW® airflow pattern provides a system unavailable elsewhere. Our BZF design is based upon the source or control capture concept. CDC says, “Source control techniques can prevent or reduce the spread of infectious droplet nuclei into the general air circulation by entrapping infectious droplet nuclei as they are being emitted by the patient (i.e. source).”



CDC ON IN-ROOM (PORTABLE) SYSTEMS
“ Portable HEPA filtration units may be considered for recirculating air within rooms in which there is not general ventilation system, where the system is incapable of providing adequate airflow, or where an increase in ventilation is desired without affecting the fresh air supply or negative pressure system already in place. Effectiveness depends on circulating as much of the air in the room as possible through the HEPA filter, which may be difficult to achieve and evaluate. "
“ As an alternate is the use of HEPA filtration units that are mounted on the wall or ceiling of the room if portable units are used; caution should be exercised to ensure they can recirculate all or nearly all the room air through the HEPA filter. Some commercially available units may not be able to meet this requirement because of design limitations or insufficient airflow capacity. In addition, units should be designed and operated to ensure that persons in the room cannot interfere with or otherwise compromise the functioning of the unit. "
“ Portable HEPA filtration units should be designed to achieve the equivalent of ~12 ACH. They should also be designed to ensure adequate air mixing in all areas of the hospital rooms in which they are used, and they should not interfere with the current ventilation system. "

WHAT BIOLOGICAL CONTROLS’ PORTABLE UNITS DELIVER

We have portable, stand alone, wall or ceiling mounted units all using the same basic filtration concept and air delivery system. The key CDC provision in this section is when there is the need for portable units. “Care should be exercised to ensure they can recirculate all or nearly all of the room air through the HEPA filter.” Depending on size of area to be cleaned, we can provide appropriate equipment to meet or exceed the 12 ACH (air changes per hour) required. Each product has proven its ability to clean all areas of a room rapidly, because each product has been carefully designed specifically for each individual application.


CDC ON INSTALLATION, MAINTENANCE AND MONITORING OF HEPA SYSTEMS
"Proper installation and testing and meticulous maintenance are critical if a HEPA filtration system is used, especially if the system used recirculates air to other parts of the facility. Improper design, installation, or maintenance could allow infectious particles to circumvent filtration, and escape into the general ventilation system. HEPA filters should be installed to prevent leakage between filter segments and between the filter bed and the frame.”

WHAT KIND OF HEPA FILTERS BIOLOGICAL CONTROLS USES

Any system is only as good as the HEPA filter and the seals around the filter. Since this is such a critical area, CDC recognizes that, unless these filters are properly constructed, installed, maintained and tested, you compromise the entire system by running the risk of reintroduction of infectious particulate into the environment or ventilation air system. We provide only individually tested and certified HEPA filters that meet or exceed all current Federal, military, pharmaceutical and industry standards. A filter is only as efficient as its seal. Our design is based upon a fool proof draw-latching mechanism that assures proper filter seating and sealing. Our HEPA filter is permanently sealed in a patented modular HEPA "filtercube" design that provides an absolute seal, preventing air by-pass. This system provides superior performance during operation over conventional sealing and locking procedures.

CDC ON PRESSURE SENSING DEVICES TO DETERMINE FILTER REPLACEMENT
"A manometer or other pressure-sensing device should be installed in the filter system to provide an accurate and objective means of determining the need for filter replacement. Pressure drop characteristics of the filter are supplied by the manufacturer of the filter. Installation of the filter should allow for maintenance that will not contaminate the delivery system or the area served. For general infection control purposes, special care should be taken not to jar or drop the filter element during or after removal."

WHAT BIOLOGICAL CONTROLS PROVIDES TO DETERMINE FILTER REPLACEMENT
The MICROCON® series of air purification products utilize a built-in minihelic gauge to measure air filter resistance, thereby monitoring filter replacement. Some competitive units use no gauge whatsoever; while others utilize a nonobjective "idiot" light to determine filter performance. Our systems lend themselves to "bag out" filter removal procedures which eliminate personnel exposure to contaminated filters. Most competitive systems allow for direct exposure to contaminated filters because their system design requires the proper compression of rubber gaskets to assure their filter sealing integrity.

CDC ON AIR MIXING
“ General ventilation systems should be designed to provide optimal patterns of airflow within rooms and prevent air stagnation or short circuiting of air from the supply to the exhaust (i.e., passage of air directly from the air supply to the air exhaust) "
“Adequate air mixing, which requires that an adequate number of ACH be provided to a room, must be ensured to prevent air stagnation within the room. However, the air will not usually be changed the calculated number of times per hour because the airflow patterns in the room may not permit complete mixing of the supply and the room air in all parts of the room. This results in an “effective" airflow rate in which the supplied airflow may be less than required for proper ventilation. To account for this variation, a mixing factor (which ranges from 1 for perfect mixing to10 for poor mixing) is applied as a multiplier to determine the actual supply airflow (i.e., the recommended ACH multiplied by the mixing factor equal the actual required ACH)."
“ Smoke tubes can be used to visualize airflow patterns in a manner similar to that described for estimating room air mixing.”

WHAT BIOLOGICAL CONTROLS DELIVERS ON AIR MIXING

The MICROCON® 800 AND 400 series create a CIRCUMFLOW® air pattern within the room that draws in air 360 degrees from the breathing zone. By exhausting air 360 degrees at the bottom, we create air currents and establish airflow patterns within the room to provide for propel air mixing and dilution. Our CIRCUMFLOW® airflow pattern helps prevent air stagnation, dead air layers and pockets that can exist with unidirectional (one sided exhaust) air recirculation systems. Based upon the room size and volume setting, we are able to provide the required air mixing and air change per hour (ACH) requirements as outlined by the CDC Guidelines.


CDC ON EXHAUSTING AIR FROM ISOLATION
“Air from TB isolation rooms and treatment rooms used to treat patients who have confirmed or suspected infectious TB, should be exhausted to the outside in accordance with applicable Federal, state, and local regulations. The air should not be re-circulated in the general ventilation. In some instances, re-circulation of air into the general ventilation system from such rooms is unavoidable (i.e., in existing facilities in which the ventilation system or facility configuration makes venting the exhaust outside impossible). In such cases, HEPA filters should be installed in the exhaust duct leading from the room to the general ventilation system to remove infectious organisms and particulate the size of droplet nuclei from the air before it is returned to the general ventilation system. "

HOW BIOLOGICAL CONTROLS EXHAUSTS AIR FROM ISOLATION
Both the MICROCON® EX-BB and the ExC-BB were developed specifically for this application. Both are variable HEPA filtered units that can exhaust or supply room air to negatively or positively pressurize an area. Each unit has great versatility allowing exhausted air to be directed outside or ducted directly into the ventilation system. This means of providing negative pressure has tremendous benefits over conventional engineering control in costs, time and performance. By recycling the air (once filtered) as opposed to direct outside exhaust, energy makeup costs are greatly reduced.

CDC ON DISCHARGE EXHAUST FROM BOOTHS, TENTS, AND HOODS
" Air from booths, tents and hoods may be discharged into the room in which the device is located or it may be exhausted to the outside. If the air is discharged into the room, a HEPA filter should be incorporated at the discharge duct or vent of the device. The exhaust fan should be located on the discharge side of the HEP A filter to ensure that the air pressure in the filter housing and booth is negative with respect to adjacent areas. Uncontaminated air from the room will flow into the booth through all openings, thus preventing infectious droplet nuclei in the booth from escaping into the room.”

HOW BIOLOGICAL CONTROLS' ISOLATION BOOTH DISCHARGES

The ISOPORT ® is a HEPA filtered enclosure that creates negative pressure within the booth by exhausting filtered air back into the room. The booth is comprised of tubular aluminum channels with mechanical interlocking latches that form a virtually airtight enclosure. Heavy gauge clear vinyl panels are permanently sealed to the aluminum channels. The door section is made up of two vinyl panels that seal in the middle with a full length magnetic closure strip. Plastic handles are attached to each door opening to allow ease of entry and exit.

Room air is drawn from an opening at the base of the door and flows through the booth to a rear exhaust port. A MICROCON®, positioned outside the booth with a special intake HEPA filter, is drawing exhausted HEPA filtered air back into the room thereby creating negative pressurization. By using a ceiling mounted ExC unit, negative pressure can also be created while exhausted air can be discharged to the outside.


CDC ON LOCAL EXHAUST VENTILATION

" The exterior type of local exhaust ventilation device is usually a hood very near, but not enclosing, the infectious patient. The air flow, produced by these devices, should be sufficient to prevent cross-currents of air near the patients' face from causing escape of droplet nuclei. Whenever possible, the patient should face directly into the hood opening so that any coughing or sneezing is directed into the hood, where the droplet nuclei are captured. The device should maintain an air velocity of ~200 fpm at the patient's breathing zone to ensure capture of droplet nuclei.”


HOW BIOLOGICAL CONTROLS CREATES LOCAL EXHAUST VENTILATION

The MICROCON® WallMAP PC is a HEPA filtered air purifier mounted on a tubular frame. It is portable and provides for elimination of infectious airborne bacteria during cough-inducing procedures.

The cart is mounted on four casters (two lockable), making transport easy and convenient. An all
encompassing Plexiglas shield, mounted to a stainless top, provides an intake recess area allowing for contaminated air to be pulled directly into the HEPA filter and not circulated around the room. By positioning a patient directly in front of the intake, access to the patient from three sides is possible allowing for seated or individuals in wheel chairs to be properly treated. By exhausting through a HEPA filter, air does not need to be ducted out but can remain within the room.
