This 7-CFM 3/4-HP two-stage rotary vane vacuum pump pulls a 0.3-Pa (2.25-micron) ultimate vacuum for HVAC maintenance, automotive A/C service, refrigeration rebuilds, resin degassing, and wood stabilization. A robust 4-pole high-torque motor delivers steady performance through long shop sessions, while a cast-iron and die-cast aluminum housing with a built-in cooling fan avoids overheating across multi-job days. Triple intake ports cover 1/4-in SAE, 1/2-in ACME, and 3/8-in SAE, so the AC vacuum pump connects directly to automotive A/C systems and small R134a, R22, R410a, R1234YF, and R32 refrigerant systems without adapters.
7-CFM 0.3-Pa Deep Vacuum: 3/4-HP 550W two-stage rotary vane vacuum pump delivers 7-CFM (198-L/min) with a 0.3-Pa (2.25-micron) ultimate vacuum
4-Pole Motor Cooling Fan: 4-pole high-torque motor with cast-iron and die-cast aluminum housing plus a built-in cooling fan keeps the HVAC vacuum pump stable through long
Triple Intake Port Hookup: 1/4-in SAE, 1/2-in ACME, and 3/8-in SAE intake ports hook the AC vacuum pump directly to automotive A/C systems
