The BMOS Filling Station (BMOS-FS) is a low pressure, portable 20.0 liter liquid oxygen storage device designed to fill multiple BMOS or MMOS (using the BMOS-FS Hose Kit) systems prior to use. Average filling time is approximately three minutes to fill either system. Weighing less than 125 pounds when full, the BMOS-FS can be carried by two ground support personnel or mounted in an aircraft. The BMOS-FS requires no external power and uses just two 9-Volt batteries for the quantity indicator. The system has been tested to MIL-STD-810.
