Pull deeper, faster vacuums on automotive AC, mini-split, and HVAC service jobs with this two-stage rotary vane pump. The 1-HP 110V/60Hz copper motor displaces 10 CFM (254 L/min) and reaches a 0.3 Pa (25 micron) ultimate vacuum, evacuating moisture from R12, R134a, R22, R404, R410A, and R502 lines before charging. A 500 mL oil reservoir with sight glass and 1/4-in side fill port makes mid-job top-ups quick, and the anti-backflow valve protects lines during power loss. Aluminum housing keeps the pump cool through long service days.
Two-Stage Deep Vacuum: Two-stage rotary vane design pulls 10 CFM free-air and reaches 0.3 Pa (25 micron) ultimate vacuum, eliminating non-condensables from refrigerant
All Common Refrigerants: Works on R12, R134a, R22, R404, R410A, and R502 lines, covering legacy auto AC, mini-splits, walk-in coolers, and commercial refrigeration
Big 500-mL Oil Reservoir: 500 mL oil reservoir with front sight glass and 1/4-in side oil fill port lets HVAC techs check level and top up between jobs without tipping
Anti-Backflow Valve: Built-in check valve blocks oil migration into the vacuum chamber on power drop, while thermal-overload protection auto-shuts the motor before damage
Auto and HVAC Service Use: Sized for HVAC techs, mini-split installers, automotive AC shops, refrigeration techs, and vacuum-packaging applications running long cycles
