The BMOS Filling Station (BMOS-FS) is a low pressure, portable 20.0 liter liquid oxygen storage device designed to fill multiple BMOS or DMOS 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.
