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

Product works as described. I use it for degassing silicone and resin for mold making and resin casting. Works perfectly but I have since ordered a smaller chamber to make the degassing process quicker (less volume).

Quality product, solid, well made vacuum pump & vacuum chamber. Easy to use. Works exactly the way it's supposed to. I love it & I highly recommend.

Great product, I've been using for my resin work. Very impressed how it removes the bubbles. My products are lovely and clear, However, really need instructions with the vacuum.

Great product , works very well and everything is exactly as described, delivered before the the date of delivery so I am very happy

Long run vacuum jobs are it's weakness. Still happy with the product. I am buying from Vevor again!!

Pretty good value, Perspex lid has crazing after one use but seems to hold vacuum, pump had no oil in it , which is annoying.

Very happy with the unit. Pulls 2 mbar vacuum easily and holds vac once valve closed. Only negative is that not shipped with any oil for pump.

Amazing for this price! Sucked a great vacuum, with absolutely no leaks of any kind. You could leave the the vacuum overnight with the valves closed, and in the morning it would still be down at the bottom of the gauge. But you DO need vacuum oil! And you can get it at the autopart's store. Don't ask me why they sell vacuum pump oil. But they usually do! If you're trying to boil off water or remove a trace solvent like butane, this is your pump and chamber!

The chamber is a lil small but I wasn't sure what size to order operates great does what I got it for , this was my first order from this company and I am sure I will be doing some more business with them

I was able to set this up with a little experimenting despite it shipping with no directions.A bit small, but its now set up to decompress the chamber to about -20. Shut the valve and stip the pump.I leave my resin about 3 min, crack the intake to reprssirize, heat blast the surface and depressurize again. 3 rounds and my resin is about as gas free as it gets.
