Our vacuum pump tool can cool itself and prevent itself from burning out. The built-in thermal protection prevents the machine from burning and extend the machine's life.

First impressions are great. Pulled my home hvac system down to 240 microns. Bought as a backup for my work rig, needed to test it out and had a repair to do on my own system. Pulled a large split heat pump unit with 55 ft of line down to 240 microns in 15min. I was using 1/2” vacuum rated hoses with an 3/8 “Y” adapter. Hose fittings were 3/8 on one end to 1/4 on opposite, 6ft length. After a triple evac system held at 240 for over 2 hrs before charging. Can’t really ask for more. As far as longevity- time will tell.
