The M93 GPFU provides positive-pressure collective protection for vehicles and mobile shelters. The M93 GPFU requires 510 watts of power and can be operated at 50/60 or 400 Hz single phase. The M93 GPFU uses the M48A1 Filter Canister (5-19-7435). This filter is rated at 100-cfm (170 m3/h) and performs gas and particulate filtration.
