Customer Reviews for Vevor 1.8 CFM 1/4 HP 1 Stage Air Conditioner Vacuum Pump With 2 Gallon Vacuum Chamber

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.

I NEEDED THIS IN A HURRY TO REPAIR AN ITEM, EXECELLENT PRODUCT FOR VERSATILITY AND MANUFACTURE. GREAT ITEM

I recently purchased this vacuum chamber to perform some experiments related to a PhD project. I was surprised at how good quality all of the equipment was, especially for the price! I will say that the rotary vane pump is very smoky, but our lab has an extraction system so it wasn't a concern!

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

Very useful unit already used to stabilise timber. We were very pleased with outcome. Pen blanks are great

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.

Easy to use, exceeded expectations, very quick turn around for delivery, feels very sturdy whilst in use,

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
