The 1/3 hp copper motor of our single-stage rotary vane vacuum pump delivers a 4.5 cfm flow rate capable of reducing your HVAC system up to 37.5 microns (5 Pa). System oil level and quality are easily controlled by the integrated sight hole; a funnel and a pair of gloves are included in one size fits most to make replacement quick and clean. Ideal for any user, even beginners, clear instructions guide the removal of air, water, and other gases and vapors from R-12, R-22, R-134a, and R-410a systems using their 1/4 and 3/8 inch inlet port systems. (An included adapter also allows for use with 1/2" pipe.) The innovative design of this HVAC pump prevents oil backflow and separates the exhaust flow from its oil vapor, which limits pollution and provides safer operation. The reinforced aluminum alloy housing effectively dissipates heat generated during operation and resists chemical corrosion for years of useful use, and its light weight and convenient handle keep things easily portable for transport or storage.
