Customer Reviews for 4 CFM 1/3 HP Air Conditioner Vacuum Pump With 3 Gallon Vacuum Chamber

It works as intended I use it for the acrylics. I pour to get all the bubbles out ahead of time. I would recommend it.

Quality product, good value. Arrived well packaged, easy to assemble. But the instructions are minimal and unclear if you are not already familiar with the product. Had to resort to YouTube tutorials for use, but very happy with it now that I am confident.

Super fast delivery

Still learning how to get my resin right, this is helping andit was quick to set up out of the box had it working in minures.

My vacuumed chamber did not work out of the box but customer support made it right with no hassle. Replacement unit woks great.

Overall a good product, the kit was missing a second seal ring and it would not begin vacuum . . not sealing. The Customer Service was persistent in understanding English to know what was needed. I imagine they were as frustrated as me, but stuck with the process and after a slow boat, I got the part. The interaction was clunky, but they did not hesitate. The vacuum pump pulled within a faction of the actual barometer and the valves and hoses sealed. It held a constant vacuum for more than 24 hrs. In my experience that is tough to attain. Even with the delay to put in service - it is RECOMMENDED. The best part is it has a thick GLASS cover. It is stiff and durable, and by far the best attribute of this product and alone worth the price.

Great Vacuum Chamber... Quick set-up and very easy to use... Just as good if not better than competitors highly priced alternatives ;) highly recommend this unit....

works well, works pretty quick. puts off a lot of smoke and probably better used outside, but it’s not the worst. I think it’s just burning a little oil. but hey, whatcha gonna do!? it’s cheap, it seals and pulls most the air out within 5 min or less…

The vacuum pump and chamber worked perfectly. The pump reduced vacuum to -27.5 in Hg very quickly. I was happily surpised with the performance. vacuum chamber held vacuum even when the pump was off .Vacuum didn't drop even after 30 minutes, Nice Job!

Damn better than others my friends have ,,,,Cheers for quality and its so quiet considering i live in a flat . very low smell from the pump and the vaccume seal connects first time , every time.
