Review on AUTOGEN Single Stage Inverter Conditioner Refrigerant by David West

This is a nice little vacuum pump and would fit nicely in a small vacuum chamber I built to change oil in small engines. This little pump is a force to be reckoned with! I've been using this pump regularly for a few months and have never had any problems. I've run it for over 30 hours for special applications and it uses very little oil. It runs fairly quietly and if you change the oil after each use it should run indefinitely. The 3CFM lithium battery single-speed vacuum pump is powered by a 1/4 HP all-copper motor, making HVAC maintenance quick and easy. With a flow rate of 3 cfm, it can downsize your system to 60 microns. Reinforced aluminum alloy body, efficient heat dissipation and chemical corrosion resistance. Its new design can prevent oil backflow and isolate exhaust gases from oil mist filter mechanism, reducing pollution and making operation safer. The 20V lithium battery vacuum pump can be used and taken anywhere. The lithium battery can be fully charged in two hours and used continuously for 90 minutes at high intensity for 90 minutes.
