This 200-cfm filter unit is designed to provide positive-pressure CBRN collective protection to vehicles and shelters with minimum size, weight and power requirements. The H200-24GPFU mounts through the roof or wall of a vehicle or shelter. It employs the M98 Filter Set (5-19-6722-N), rated at 200-cfm (340 m3/hr), and includes gas and particulate filters. The M98 employs ASZM-TEDA carbon and glass micro fiber particulate media per MIL-F-51079 with particle efficiency greater than 99.97% @ 0.3 microns.

The H200-24GPFU electronic control system consists of a motor controller (MC), system control module (SCM) and system control display (SCD), each installed separately for maximum flexibility. The SCM monitors differential pressure between the TFA and the external environment. Based on this pressure, the SCM sends speed control signals to the MC to maintain TFA pressure between 1.5 IWG and 3.0 IWG. The SCM also sends warnings and status signals to the commander console and SCD.

The MC receives the power feed (28 Vdc) from the vehicle and distributes it to the fan motor and SCM. The MC also provides a contact closure to control a remote device, such as an air damper. The SCD provides the human interface, including pressure differential gauge, low/high pressure alarm, fault signals and On/Off switch.
