Review on 🔧 Efficient AUTOGEN 2-Stage Air Vacuum Pump 5CFM 3/4HP 0.3 Pa - Perfect for HVAC/AUTO AC Refrigerant Recharging, Wine Degassing, Cow Milking, and Food Processing by Matt Weber

The pump worked great and I knew it had no oil in it. Vacuum pump oil isn't considered cheap, of course, but it's a good idea to package it with the oil so you can refill and use it once you've received it. Otherwise great pump for the money. Quiet and brought the vacuum down to -29 inches on my gauge. Pays for itself with a self-service air conditioning system. This job required me to replace a condenser on my 2010 Grand Cherokee. At the same time I did all the gaskets and the receiver / dryer. Pulled the vacuum cleaner for 20 minutes, left for 30 minutes with no loss. Enter r134a and off you go.
