The QS5 Vacuum Pump is a two-stage, rotary vane pump with 5-cfm rated displacement for ultimate vacuum down to 15 microns. It is designed for quick, deep evacuation, as well as affordability and durability, says the manufacturer. The large oil sight glass, easily accessible oil drain, and innovative oil-trapping exhaust/demister allow technicians to make easier, more efficient service calls. The anti-backflow on the inlet prevents oil from flowing back to the system if there’s a power disruption. The gas ballast allows pumped water vapor to be exhausted to the atmosphere instead of accumulating in the oil reservoir. The pump’s design includes a comfortable no-slip grip for easy carrying, and its solid construction delivers durability. The thermally protected motor ensures safe operation. The oil drain and inlets have tethered caps, which eliminates dropping or losing them. The vacuum pump carries a two-year replacement warranty.
