The Best Gast 1531 Vacuum Pumps

Robinair’s No 15600 CoolTech 2-stage rotary vane design vacuum pump features a 6 CFM free air displacement along with the power and capacity needed for a wide range of service applications. This high-performance unit includes a heavy duty, 1/2 HP, 115V/60Hz thermally protected motor that delivers high torque for easy startup and efficient operation. Factory rated to 15 microns, this unit delivers a fast, thorough evacuation. Offset rotary vanes build powerful compression within the pumping chamber – reducing pressure and vaporizing moisture. Gas Ballast design mixes moisture laden air passing through pump with relatively dry air so compression doesn’t cause condensation. Iso-Valve isolates pump from system with just a quarter turn. Durable molded polycarbonate base improves pump balance and minimizes vibration while in operation. Also includes: 1/4″, 3/8″ and 1/2″ 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. Thoughtful design and robust construction ensure this UL approved unit will deliver the high-performance professionals demand. Robinair CoolTech vacuum pumps are designed for use on A/C-R systems using CFCs, HCFCs, and HFCs in conjunction with mineral oil, ester oil, alkylbenzene oil, and PAG oil as lubricants. Not for use with ammonia or lithium bromide systems; not for use with flammable refrigerants. Oil included. Robinair, a Bosch Automotive Service Solutions brand, is a global leader in service tools and equipment based in Owatonna, Minnesota. Robinair is recognized throughout the world as the quality and performance leader in AC/R evacuation tools and this position has led to its success with the full range of products that serve the heating/ventilating/air conditioning/refrigeration (HVAC-R) and mobile markets, which includes the automotive aftermarket along with other industries such as agriculture and construction.
