Customer Reviews for 8CFM Two-Stage Rotary Vane Professional Vacuum Pump (15Micron, 1HP, 1/4"flare 3/8 SAE 1/2"ACME inlet)

works really fast

Used for HR freeze Dryer . NO MORE LOW VACUME ERRORS. Needed to Fabricate a check valve. Needed to drill and tap for drain valve. Needed to use a motor starter Relay "00" size for power. & End Bell cover needed Shims, The fan was Interfering. Went with two pumps this one and original HR pump. Also needed one more suction line and a "JIC" "T" for plumbing. Would I do it again? Yes

Works beautifully and no oil leaking or mistake at all. It is whisper quiet and achieved -29 InHg within a few seconds. See my photos. I hardly ever write reviews but this is an exception. I highly recommend this pump.

This product works it'd be nice if it came with a little more fittings but hey it pulls enough vacuum to boil water

First impressions are great. Pulled my home hvac system down to 240 microns. Bought as a backup for my work rig, needed to test it out and had a repair to do on my own system. Pulled a large split heat pump unit with 55 ft of line down to 240 microns in 15min. I was using 1/2” vacuum rated hoses with an 3/8 “Y” adapter. Hose fittings were 3/8 on one end to 1/4 on opposite, 6ft length. After a triple evac system held at 240 for over 2 hrs before charging. Can’t really ask for more. As far as longevity- time will tell.

It works great and basically does whats its supposed to The only issue i have is that it gets hot when used for a long time

Pulled it out of the box filled with the oil it came with and pulled a system down within 30 mins. And it was extremely quiet which was a pleasant surprise.

I purchased it for vacuum chamber experiment, and it worked great!! This product is the best cost efficient.

I bought this vacuum pump for prepping epoxy. It's a tiny bit slow but I have a very large vacuum chamber so I expected that. Pulls down amazingly well!

Unit is well built/sturdy, easy to set up, and operation is smooth/quiet.
