Review on 🔧 High-performance AUTOGEN 4CFM Single-Stage Air Vacuum Pump - Ideal for HVAC/Auto AC Refrigerant Recharging Manifold Gauge Set by Emmanuel Chouinard

I ordered this r134a vacuum and charge pump for my two jeeps. One had a shredder valve leak and the other had a hole in the condenser. After the repair, I used it to vacuum at -30 for 20 minutes to remove all moisture. The instructions were simple, so I would like to point out that when adding vacuum oil, be sure to pour it into the red-handled port. The big black cap acts as an exhaust, so that's important. After the vacuum I used the manifold to fill R134a to specification for both machines. I would recommend!
