Heavy Duty 1/3Hp Hvac Vacuum Pump With 4.5 Cfm Single Stage Rotary Vane For Air Conditioning Refrigerant Recovery And Leak Testing Ultimate 5Pa Performance
✔️ 4.5 Cfm Rotary Vane Design With Aluminum Housing And Copper Winding
The 1/3 horsepower rotary vane ac vacuum pump strips moisture and non-condensables from sealed cooling loops before you recharge refrigerant. Technicians rely on this heavy duty tool for residential split systems, commercial chillers, automotive climate controls, and basic leak checking runs.
✅ 4.5 cubic feet per minute flow rate for quick evacuation cycles✅ 5 pascal ultimate vacuum level to pull tight system moisture readings
✅ Integrated backflow check valve that stops compressor oil from spilling backward
✅ Front facing quarter inch oil fill spot paired with an easy drain plug
✅ Built in thermal overload cutout that kills power when the copper winding overheats
✅ Clear sight glass window and reinforced carry grip for shop floor mobility
💡 What makes a rotary vane vacuum pump handy for pulling deep evacuations on split systems?
The main trick involves trapping air against a rotating shaft instead of pushing it through a piston chamber.
- A single stage rotor design creates consistent scraping friction that hogs out trapped pockets of moisture
- Constant blade contact maintains tight clearances even when the ambient shop gets hot
- Low dead space volume prevents residual vapor from bouncing back into your manifold gauges
