Badass Two Stage Rotary Vane Refrigerant Vacuum Pump With Pressure Gauge Hits Four CFM For Lightning Fast High Vacuum In HVAC And AC Systems With Gas Ballast To Cut Condensation

Single Pump Unit TwoStage Refrigeration Vacuum Gauge
✔️ Rotary Vane Motor Drives Fast Air Removal From Lines

This four CFM refrigerant vacuum pump strips moisture and noncondensables straight out of HVAC rigs. Techs grab these units to evacuate AC lines, chase leaks, and prep charge ports before injecting Freon or ecofriendly blends.

✅ High speed rotary vane mechanism pulls deep vacuums fast
✅ Integrated dial gauge tracks exact depression levels
✅ Gas ballast ring vents trapped water vapor from the chamber
✅ Anti reflux trap stops atmosphere from pushing back into hoses

💡 Why do technicians prefer a two stage oil pump for AC evacuation tasks?
To clear moisture quick, this handy device moves double the airflow compared to basic setups.
- Dual stroke action compresses air more efficiently than single stage models
- Ballast valve prevents water vapor from mixing with clean pump oil
- Rotary vanes handle continuous run times without overheating
- Direct view pressure display eliminates guesswork during leak checks
