The FFA100 is a modular CBRN fan filter assembly/air filtration system. Designed for mobile applications, the FFA100 can be configured as a push-thru or pull-thorough filtration device with a quick filter replacement retention system. The FFA100 can be mounted horizontally or vertically on one of the unit’s three different mounting surfaces. Capable of providing up to 100 CFM (170 m3/h) of filtered air from CBRN contaminants into a protected enclosure, or Toxic Free Area (TFA), the FFA100 creates positive pressure up to 4 IWG (1000 Pa). Its modular design offers the choice of a low efficiency or high efficiency inertial particle separator (IPS).

  • Push-Thru filtration systems push air through the filter into the TFA. The filter is in positive pressure. This configuration requires the system to be installed outside the TFA. Filter replacement is handled from the vehicle exterior. The high efficiency particle separator does not require a scavenger fan with push-thru filtration system configurations.
  • Pull-Thru filtration systems pull air through the filter into the TFA. The filter is in negative pressure. This configuration requires the system to be installed inside the TFA. Filter replacement is handled from the vehicle interior, or through special exterior access provisions through the vehicle armor. The high efficiency particle separator requires the addition of a scavenger fan.
