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

awesome little setup. pump is WAY stronger than i expected! i made the mistake of not watching the hose and some of my acetone/poly-acrylic climbed into the pump/oil reservoir while it was running. i didnt know this at the time and i didnt find out until a few days later i went to turn it on and the pump was seized up (due to operator error) because the fiberglass paddles got gunked up and couldn't expand or retract which created the vacuum, because of the junk i let get inside. so i took the pump apart and sanded the paddles down and slapped her back together and she works great! i keep the hose in an "A" shape while I'm running it so pump oil cant get in the chamber and also my epoxy mix doesn't get sucked up inside the pump.. gravity saves the day again.. great little pump.. i was really amazed at the quality of the machining and materials. (I expected much less for what it cost.) if you're looking for a vac chamber...well... this little setup is worth EVERY penny...! just keep the hose high in the center!

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
