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

The product is working fine for me and have no complaints .

I adore this vacuum chamber. I'm a resin artist, and I was curious about getting crystal clear resin with a vacuum pot (which is kind of hard), but it works SO well for silicone mold making. It's easy to use, right out of the box. The vacuum pump does leak a little bit of oil as it's in use- but I put a paper towel under it and it's fine. It's fun to watch the bubbles pop in the surfaces you put inside! Great seal, easy to assemble. Instructions are a little vague, but, there are plenty of tutorials for this machine on youtube.

It does what it is supposed to do. I had some air leaking in were the gauge goes through the acrylic top. I have no idea what gaskets would work so I just sealed it with some epoxy. =PNow it holds great. Good value.

Important to know: you really have to tighten the nuts around the rubber gaskets that seal the valve/gauge attachment to the lid on the vacuum chamber, like super tight or you won’t get a proper seal. Overall, a good value for the price. Both pump and chamber work fine so far, I’ve used them like a dozen or more times.

This is a really nice set up for less than $90.00. I got a perfect little vaccum chamber that works perfectly for making Shatter and Honeycomb! It pulls a full vaccum fast and holds it when the valves are closed and the pump is turned off. It doesn't allow the vaccum to slowly seep away while sitting,it holds for as many hours or days as you need it to. Great deal. I am happy very with this purchase!

I purchased this unit to de-gas my blended hot sauce prior to pasteurization. The repeated blending steps of the sauce introduce a lot of air, and it is a major quality improvement if this can be removed prior to bottling. This vacuum chamber works perfectly. It is also very helpful that it fits and seals perfectly on my double boiler to allow me to complete this task without pouring the sauce into the chamber pot. In addition, the quality of this product is really very good. I have used it for about 25 hours and I do not have a single problem. This clear cover is a critically important characteristic. As you vacuum a liquid, the volume of the liquid expands. The clear top allows to you observe the expansion and stop the machine if the expansion threatens an overflow. Over all, this is a great machine and I am so glad I choose Vevor over other vendors. As a side note, I have also used it to vacuum 8 ounce product bottles to provide a better isolation for the product during the shelf=life. Again, thank you VEVOR!

The best bang for the buck. This is worth every penny. Getting quite a lot of use out of this Vacuum system. Anyone that dabbles in acrylic pouring needs this.

This vacuum chamger arrived well packaged and was easy to setup. So far the only issue I've had is the chanber itself is very narrow. We use it to stabalize wood and to make handle scales and as narrow as it is we can only do 2 at a time. That's 2 sides not 2 sets, other than that the pump works great although it's a little loud.

Vacuum chamber and gauge supervisor quality, very nice. The vacuum pump had some issues and needed to be returned. Return made easy thanks to Amazon.

The whole thing was easy to set up. My problem was with the oil ( definitely my fault on that one) I over filled it but I didn’t have a clear instruction on how I should go about filling it up. Other than that it works perfectly for what I need.
