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

Great pump, works great. Just at start up for a couple minutes it has alittle atomized oil coming out the exhaust

This vacuum chamber is perfect to use in sealing not only Mason Jars for food preservation, but also pickle jars, Salsa jars or others with a sealing lid. I just put the closed jar into the chamber, pull a vacuum, and then release. The lid will pull down sealing the contents in an air tight vacuum to help keep my dehydrated foods safe. This saves me money by allowing me to reuse my condiment jars and not throwing them into the land fill.

Excellent quality. Works exactly as advertised. Great videos found for set up and use online since Vevor does not provide a setup/ instruction manual. Just the pump manufacturer manual is included.

Worked great. Quieter than I expected. I have tried this a couple times so far and it works like it’s supposed to. I use it to pull bubbles out of plastisol while making soft plastic lures. Made crystal clear baits! Costs less than other brands and does the same job.

Works well make sure to keep eye on oil level Did smoke a bit when first started but seem to clear up After few times

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!
