VEVOR 3 Gallon Vacuum Chamber and 3.5 CFM Pump Kit, Stainless Steel Chamber, Single Stage Vacuum Pump Degassing Chamber Kit, with Acrylic Lid, Oil, 4.92 ft Hose, for Degassing Resin Silicone Epoxies

I tell you for the money. this thing is great. I've used it several times. good volume, good size. I'm happy with the pump. nice and quiet. just as people stated. the only thing I would say that's a little bit annoying is that there is when unvacuumed the vacuum chamber domes out so it doesn't sit flat on a table. once it pulls a vacuum that comes up it sits nice and flat on a table. no wobble

Very high quality kit for the money, especially on sale. I was worried about the amount of noise the pump would make but it turned out to be quieter than a vacuum cleaner. Had no problems with sealing and was very easy to use.

Made easy work of degrading epoxy. I expected a clear top and that wasn’t the case. The ad clearly shows a loss that you can see through but t unit included a thick wooden top! Doesn’t help with me monitoring the resin. For that I’ll subtract a star. As for degassing…it does exactly what it’s supposed to but that window would help me monitor and cut out the guess work.

Works great !!! Thanks

I've only had it a couple of weeks, but this thing is a beast! I started with one of those crafty type vacuum chambers. It was aggravating. The top was hard to get off. It wouldn't fit more than a 12 oz cup, and I felt like I still had the occasional bubble. And when I tried this thing I could see why. My old vacuum chamber would cause a thin layer of bubbles on the surface. Watch my video; my 3 oz of epoxy almost overflowed with all the air that got sucked out by this! And I can fit 32 oz cups in it, and the top pops off very easily. It's not perfect. I did like the automatic-off timer on my other one. And sometimes I need to push on the top for a second at the start to get it to seal. Also, once you turn the pump off on this guy, you can't turn it back on without releasing the vacuum in the chamber first. But these things can be worked around, and it's hard to argue with its performance, and for a pretty reasonable price.

This product has changed my resin game. To be clear, I mix my resin (with color) in "smaller" batches (I'm not doing deep pours) and then I put the resin in the cup it was mixed in into the vacuum chamber and let her rip - creating vacuum and releasing it until pretty much all the bubbles are gone. Then I pour and I get crystal clear results. Now depending on colorants it can take longer to pop bubbles so make sure you have pot time (ie that the resin can stay in the cup that deep for that long). If not then you might want to put it in the mold but if you are doing smaller, silicone molds like me then keep in mind the vacuum is messy! It makes the resin bubble up and I have to kill it before it bubble over and then it leaves a trail on the way back so after it cures it will need clean up. Far better to be able to vacuum it in the cup and then pour.

For the price it's working great. I use it all the time to seal 1/2 gallon mason jars. Great for food preservation.

I ordered this recently and had, what I believed to be a fairly minor and easily remedied issue with the pressure gauge needle being stuck. Everything else about the product appeared to work as advertised. I contacted Vevor's customer service, and either the response to the issue was AI with a learning disability generated, or the person answering literally had no clue whatsoever. I was initially offered free accessories, which I declined. Only after I told them I was sending back for a refund did they attempt to address to gauge issue. Too late. Any product with the Vevor name might or might not work, but the customer service was horrendous.
