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

Easy to use. Fill pump with oil, connect hoses, drop on gasket, turn on. Held a vacuum all night. No regrets with this purchase.

It worked perfectly to degas and remove moisture from mineral oil. It’s amazing how much water can be trapped in oil, but it bubbled out moderately vigorously at -24 inHg. Super easy to assemble with good instructions and intuitive to use. It doesn’t come all the way filled with oil, for understandable reasons, so be prepared to buy some proper ISO 32 vacuum pump oil. It was on sale, so that’s a plus. Overall a great product and I highly recommend it. It will be used in the future to degas resin and silicone, as well as desiccation duties.

When I first received this it did not work. After making a video to show the tech's it was not working, the response took a few days. The response I received was that that they would send me a new gasket. I did not believe that was the problem. After a week or so I did get a new gasket, but not a replacement one, but the other half that was missing in the original order. If they hadd told me that I was missing one side of the gasket I would have realized the issue. The instruction manual pictures and instructions are so poor that I did not realize I was missing the part.

Seems very good quality I haven't had a chance to use it yet but it's built a lot better than most of the ones I've seen and at a much reduced price

Works great, but lacks instructions nor any good instructions on internet in general. You must fill oil by removing the orange cap and placing in that hole the orange cap reveals, you need to run a bit, wait, and repeat until the oil gets to glass chamber so u can see it.

I buy alot of stuff from Vevor and never disappointed with my purchases, This VEVOR 2 Gallon Vacuum Degassing chamber holds a good vacuum for a very long time if doing resin projects I would recommend

I bought this to remove bubbles in my resin before casting miniatures. I only make a small amount of resin at a time so this small vacuum works well for me. The only bad point about this is it doesn't have the instructions to install and guide how to use it, I had to search YouTube for it. There is no mat in this kit, but the price is the cheapest on the market, so no complaining about this.

Works well, hard to beat for the price. Pump generates a little more fog than I would like but not an issue in the garage.

Everything was as described, items where packed very well. We where pleased with the performance. We will be back for more.

awesome little setup. pump is WAY stronger than i expected! i made the mistake of not watching the hose and some of my acetone/poly-acrylic climbed into the pump/oil reservoir while it was running. i didnt know this at the time and i didnt find out until a few days later i went to turn it on and the pump was seized up (due to operator error) because the fiberglass paddles got gunked up and couldn't expand or retract which created the vacuum, because of the junk i let get inside. so i took the pump apart and sanded the paddles down and slapped her back together and she works great! i keep the hose in an "A" shape while I'm running it so pump oil cant get in the chamber and also my epoxy mix doesn't get sucked up inside the pump.. gravity saves the day again.. great little pump.. i was really amazed at the quality of the machining and materials. (I expected much less for what it cost.) if you're looking for a vac chamber...well... this little setup is worth EVERY penny...! just keep the hose high in the center!
