Robinar VacuMaster™ 5 CFM Vacuum Pump

HVAC high performance vacuum pump is engineered specifically for air conditioning and refrigeration service, and built with Robinair's proven offset rotary vane for fast, thorough evacuation. The two-stage, offset rotary vane design provides powerful, quiet high vacuum capability and assures moisture removal, while the high pumping capacity reduces evacuation time. Direct exhaust causes the exhaust to expel through the handle to direct it away from the service technician. Oil drain valve is positioned at the bottom of the oil reservoir and angled for faster, more complete draining. Oil fill port makes adding oil simple since the port is accessible from the front or either side. The sight glass on the front of the pump shows you when enough oil has been added. 1/2 In. ACME and 1/4 In. MFL intake fittings.
