Robinair (15501) VacuMaster Economy Vacuum Pump - 2-Stage, 118 liters/minute

Robinair's VacuMaster Economy Vacuum Pump is designed for air conditioning and refrigeration service.
featuring a 2-stage rotary vane design, 7.5 ounce oil capacity, and non-skid feet.
118 liters/minute (5 CFM) free air displacement.
1/3 HP, 220V/50 Hz thermally protected motor for international use.
Features an inlet fitting engineered for maximum airflow, while preventing oil backflow, and finned aluminum surfaces that dissipate heat faster, keeping the pump cooler and extending life.
1/4 inch MFL & 1/2 inch ACME inlet fittings, 3/8 inch FFL x 1/2 inch Acme adapter, easy to read sight glass, easy access oil fill port, and angled oil drain valve for faster, more complete draining.

Robinair's CoolTech 2-stage rotary vane design vacuum pump features the power and capacity needed for a wide range of service applications as well as robust construction for a long service life.
Powerful 1/2 HP, 115V/60Hz thermally protected motor, 6 CFM free air displacement, and factory rated to 15 microns for a fast, thorough evacuation.
Offset rotary vanes build powerful compression within the pumping chamber - reducing pressure and vaporizing moisture.
durable molded polycarbonate base improves pump balance and minimizes vibration.
Iso-Valve isolates pump from system with just a quarter turn.
Gas Ballast design mixes moisture laden air passing through pump with relatively dry air so compression doesn't cause condensation.
1/4, 3/8, and 1/2 inch male flare inlet fittings, easy to read sight glass, easy access oil fill port, and angled oil drain valve for faster, more complete draining of the reservoir.
