description abstract	Description of Driving Event: The units contain a vacuum pump driven by 1/2 HP electric motor, a shutoff valve, a vacuum break valve and an oil trap tank. The -1 and -2 units consist of GFE previously used on the apollo program and modified by the addition of quick disconnect couplings, a vacuum read-out gage, and fluid hoses. Also, replacement of components not compatible with the fuel cell coolant FC-40 and electrical system modifications have been made to meet shuttle program use requirements. The pump has provision for oil separation; however, if the system's volume is sufficiently large, oil vapor may be sucked from the pump into the system.
