Review on 🔧 Elitech V700: Ultimate Intelligent HVAC Vacuum Pump for Automotive – Next-Gen 7 CFM 2 Stage with Touch Screen App by Marty Drury

I took this to assemble the suction system for changing oil and other automotive fluids. Connecting to a canister system provided more suction than I thought it would. I didn't really like 7CFM but after using it my opinion changed. It cannot be used to suck up liquids directly, it just creates a vacuum for the canister from which things can be sucked into the canister. It mentions HVAC but I haven't used it for anything HVAC, just a canister to remove oils and stuff from car engines. Overall I'm happy with it for the application I chose it for, it works well, isn't too loud and does its job.
