## Description

Description Evacuate automotive units and other low-tonnage units quickly with this powerful portable AC vacuum pump from Orion Motor Tech! 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.

Review: Herramienta muy buena de muy buena calidad los materiales
Review: I was looking into vacuum extraction for oil changes and decided to buy a pump. This worked fantastically and easily drew a strong vacuum on and off for about four hours in a leaky DIY fluid extractor while I failed miserably at getting the tube I was using to actually draw oil out of the pan. While my attempts at oil extraction were abysmal, the pump was not, and it easily moved the oil up multiple feet of tubing when tested. It has worked great since in other projects, such as degassing silicone molds and vacuum bagging carbon fiber composites. One gripe I have with this pump is that it did not come with enough oil to properly fill it to the minimum oil line, so I had to go out and buy more, which was not easy because the type of oil is not labeled on the bottle. If this problem were addressed, it would easily be 5 stars.
