AAF International pioneered many of the techniques and systems which are used to provide cleaned and tempered air for environmental safety systems. AAF specializes in systems that handle toxic, hazardous, and radioactive gas streams . . . removing the contaminants so that the discharge can be safely used or blended into the atmosphere.

Available products include:

AAF Side Access Filter Systems - allows filter servicing to be performed by personnel stationed outside the housing. The Bag-In/Bag-Out housing can be supplied with any number of connected sections to contain roughing filters, pre-filters, HEPA filters, carbon adsorbers, and in-place test sections

AAF Walk-In Housings - specially sized access doors accommodate maintenance equipment and personnel in protective suits, if required.

Carbon Adsorbers - the AAF carbon tray is a removable, refillable, carbon adsorber cell used to adsorb radioactive iodine from atmospheric air in a nuclear power plant. The AAF adsorbent carbon is granular, activated coconut shell base charcoal, impregnated with KI and I₂, TEDA, or a combination of both. Other adsorbents are available.

Cooling Systems - nuclear class coils are finned tube, counterflow assemblies in unit casings to cool or heat air passing over the finned surfaces, using water as the heat transfer medium. Coils are available separately, or mounted in self-contained housings, along with a fan to draw air over the heat transfer surfaces in nuclear power plant applications.
