Review on 🔧 FAVORCOOL FC-30T 3.0CFM 1/4HP Single-Stage Rotary Vane Vacuum Pump with 1/4" Flare Inlet Port for HVAC Car Truck A/C AC Refrigerant Charge R410a R134a R22, Wine Degassing, Milking, Medical, and Food Processing by Tay Fair

Good little pump for the money. I'm just experimenting and don't want to invest too much. It reads -29.5 on my meter no matter what it takes. I have a lab double stop that can handle -28, but I wanted something less. This is the first oil seal pump I've used and overfilled resulting in a mess of oil splattering into the chamber as well as into the exhaust. So don't do that ;-) after draining and cleaning some, it works fine and is no louder than a diaphragm pump.
