Vacuum Chamber, 3 gal

Was packaged well in the box. I felt the edge of the chamber was going to be too sharp and tear the seal under vacuum, so I took a few minutes to sand down the edges with a little 400 grit sandpaper. Easy to assemble too. Most of the time the chamber gets a vacuum just by setting the lid on and flipping the pump on. If it doesn't immediately start, I have to apply very little pressure to get it to work, or just pick the lid up and set it back on the chamber. Holds a vacuum for over 24 hours. I have no problem leaving this chamber unattended. Operates just fine at 130F This is the best vac chamber I have ever purchased.

I use a 5hp dual stage pump to pull vacuum in this chamber and it holds up perfectly. I've pulled full vacuum in this chamber over and over and its never even made a noise. The top is thick and strong, the rivets that hold on the handle are top notch and do not leak. After a few uses the red gasket in the top will sometimes get a little ridge in it where the top pulled down onto the chamber and will sometimes leak a little if you align the gasket in a little different spot but normally after pulling for a few minutes it will pull down tight even if its aligned to a slightly different spot on the gasket ring. This thing works great and holds any material I am trying to degas without issue.

Pot and lid seem to work ok but was received with a non working vacuum gauge and after numerous calls to the support number which is only an answering machine I have not been contacted by ProVac. Not impressed by the support of this product. Wish now that I would have returned to Amazon for a different brand. If support is important to you avoid this product.

This is exactly what I was looking for at a good price. The first chamber I received would not hold a seal for some unknown reason. I didn't want to play around with the fittings or tighten too hard on the acrylic. I contacted the seller and told him what was going on. They emailed me a packing slip for the return and next day aired me a new one at no additional charge. I tested the new chamber and it worked perfectly. Been using it heavily for about a month now and I love it. I would highly recommend going with this seller because in the highly unlikely chance you get a lemon, it will be replaced. That is all.

Great chamber for degassing. has really turned my life around in terms of quality of product and people keep wanting more. however... When I received mine, the pressure gauge had been damaged and only allowed the needle to travel half the total distance. no real problem, except I do not know when to turn off pump. after roughly 15-25 times of using the chamber, I noticed there were small cracks stemming from the valve hole in the plastic. after a few more times of operation, the cracks multiplied and ran along the plastic lid. still degases fine, but will not hold pressure like it did when out of the box. I am currently trying to replace lid and gauge but am struggling to find parts for this chamber.

Just got it today and put it straight to use right out of the box it still is currently in use and has been holding a vacuum flawlessly all parts are working great. I recommend this to anyone looking for a great vac chamber this is the one to get, I had tried a different vac chamber previously and it was a piece. Pro Vac did it right good job!!!

So far it works great! The gauge doesn't go all the way to 30 only to 28, but it completely degassed my silicon with no problems! Maybe the gauge is faulty. it keeps the pressure for 2 hours with no leaks! haven't tried it for a longer period but I'm sure it will have same results.

good chamber....the lid is poorly cut and has jagged edges....the seal looks to be made of a crappy pourable material that is already beginning to detach....and the hardware use to attach the the gauge and hoses was complete junk....i had to rebuild the whole thing seeing how it arrived to me with stripped threads and poorly sealed threads...and the crappy vaccuum guage is approx. 3lbs off....for a company bragging bout its AMERICAN MADE PRODUCT it sure is constructed poorly....

All as expected, Thanx Lots

I use and talk a lot about this vacuum chamber in my videos --- "The Vacuum Infusion Test" Start with Part 1 https://youtu.be/G_f0BLaIrIE

Wouldn't hold a vacuum. Ended up with a soft rubber hose split open to make a gasket around the pot, works perfect now Rip off for price

found the product to be ok for my use. a cheaper alternative for degasing silicone especially compared to some of the other products.

Needs extra valve and fittings
