Customer Reviews for VEVOR Vacuum Chamber with Pump 3CFM 1/4HP Single Stage Vacuum Pump with High-Capacity 5 Gallon Vacuum Chamber, Vacuum Pump Chamber Kit Vacuum Degassing Chamber Kit for Air Conditioning Systems

Works as advertised. The valves are nice and tight. Closing valves with the chamber evacuated appears to hold the vacuum indefinitely.The item was roughly handed in shipping, survived okay but most of the oil had spilled out of the pump. I had to buy oil to get it up and running.Pulls a good vacuum, about as good as it gets for a one-stage pump of the type. Unless it dies prematurely it will have been a great deal for the money.

The product was shipped very fast. Arrived in great condition. Also it was exactly what I was expecting and so far has worked better than expected
