FFA400-500 400-CFM CBRN Filtration System with flow control.
Application Statement: Key Features:
The FFA400-500 is the second generation of the FFA 400-100. It is a compact, all weather, portable, positive pressure CBRN filtration system that can provide up to 400-cfm of clean, safe, breathable air for mobile or permanent shelters. It is stackable and transportable; the FFA400-500 is ideal for mobile command and medical shelters, as well as permanent shelters. The modular design of the FFA400-500 allows for multiple units to be combined for requirements greater than 400-cfm. The skid base framed construction allows for two units to be readily stacked, during operation or transportation. The FFA400-100 consists of a passive inertial particle separator, blower driven by a variable speed motor, two M98, 200-cfm gas and particulate filter sets, a filter housing and a frame assembly. The motor speed is varied electronically to maintain constant flow (400±20-cfm) under variable temperature and altitude conditions and as the filters get loaded. The speed control unit is capable of receiving external speed signal from an auxiliary device such as the pressure control (SCM) used on the M93 (5-19-9118). The system is equipped with a corded handheld remote control, which includes the On/Off switches, system performance indicator, as well as fault conditions. The FFA400-500 is an ideal system for integration with tent complexes and environmental control systems such as the FDECU, LECU etc., and as a part of fixed installations egress and ingress airlock system. A special 'Y' cable has been added to allow the FFA400-500 to receive its power from the FDECU or LECU split phase connectors.
