Protection Against Airborne Biological and Chemical Contaminants

American Air Filter has been providing extremely high levels of ultra-clean air for many years to the healthcare, pharmaceutical, food processing, nuclear and electronics industries. The AAF AstroCel high efficiency particulate air (HEPA) filter is used in cleanrooms all over the world and is the most efficient filter on the market. All AstroCel filters are individually scan tested to ensure they meet rated efficiencies and resistance.

With the heightened awareness of dangerous airborne and negative  biological, chemical, and nuclear contaminants, AAF has combined their proven HEPA technology and knowledge of positive pressure ventilation to develop specific products designed to protect occupants of commercial and public buildings from the risk of airborne contaminants including Anthrax spores until the airborne threat is eliminated.

The US Center for Disease Control, OSHA, and the US Nuclear Regulatory Commission recommend positive pressure ventilation with HEPA filtration for isolation from airborne biological pathogens.

AirShelter^TM HFS
(HEPA Filtration System)
The AirShelter HFS allows you to take control of the air you breathe. Easily installed by most HVAC contractors, the AirShelter HFS is actually an enclosed space created by positive pressure and supplied by HEPA filtration. Positive pressure means that no contaminated air can enter the protected AirShelter space because the air pressure in the AirShelter room is greater than the air pressure outside the room. When properly installed, the AirShelter is virtually 100% effective in removing particles in the 1 to 2 micron range or the size of Anthrax spores.

Adaptable to a variety of applications, designated AirShelters can be created throughout a facility using the appropriate number of HEPA filtration systems. In large buildings, one AirShelter room can be created for each floor. Shopping malls, schools, theaters, and commercial buildings should all have protection against airborne contaminants. The AirShelter HFS includes ceiling and floor-mounted HEPA filtration systems with associated monitoring and control equipment. Learn more about   AirShelter HFS.

AirShelter^TM BIBO
(Bag-In/Bag-Out Multi-Stage Filtration System)
For larger areas and mission-critical areas such as government buildings, police stations, military facilities and computer control rooms, AAF recommends the AirShelter BIBO which was specifically designed to protect against radiological weapons as well as gaseous and chemical threats. The AirShelter BIBO creates an enclosed space under positive pressure that is supplied by a series of HEPA filters along with specially treated carbon filters to protect against radioactive isotopes.

Featuring pressure-sealed, stainless steel filter enclosures and containment bags with internal gloves, the AirShelter BIBO ensures all contaminants are maintained inside the filters during filter removal and disposal. When properly installed, the AirShelter BIBO is virtually 100% effective in removing particles in the size range of Anthrax spores, chemical warfare agents, or the airborne dangers associated with radiological weapons.

Adaptable to a variety of applications, the AirShelter BIBO is also suitable for creating negative pressure spaces to isolate contagious organisms such as TB and smallpox. The AirShelter BIBO can be sized to protect any air volume requirement including entire buildings. Skid-mounted, it is suitable for rooftop or indoor installation and can be easily installed by most commercial HVAC contractors. Learn more about   AirShelter BIBO.

MailShelter^TM
Mail Handling Made Cleaner and Safer
Specifically designed to minimize the risk of inhalation or cutaneous Anthrax or other airborne diseases in mail handling and sorting applications, the MailShelter utilizes HEPA filtration to minimize the danger of airborne contamination. The MailShelter incorporates a special "glove box" which is attached to a proven AAF particulate collector to isolate a mail handler from harmful airborne particulate while opening and processing the mail. By maintaining negative pressure in the "glove box", any airborne contaminant is quickly and completely pulled into the HEPA filter system before it can escape into the user's breathing zone.

MailShelters can be sized for most mail-handling applications and are designed to accommodate and completely encapsulate standard mail delivery boxes. Learn more about the   MailShelter from AAF.
