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

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.

Where do I send this vacuum pump back to.leaks to much oil out of vent .came with oil in it . directions said it comes with out oil in it.sounds like it was used before. I want to return it

10/10! this vacuum pump has been amazing. very easy to use and makes doing automotive a/c services a breeze when it comes to vacuuming before recharging the system.

This vacuum pump has been up to the task. It has cut my evacuation time considerably compared to my previous vacuum pump. I only work on small A/C systems "under 5 lb capacity" so larger systems may tax it more. However, this pump is great for automotive A/C systems.

Works fast to recover. Must have. I had 1/3 one. Night and day. Comes with everything even oil. I highly recommend this. The price is amazing for this unit. I shopped saw this. Was comprehensive. You wont regret it. You will if you dont.

At first I was pretty disappointed with this vacuum pump. It struggled to achieve the same vacuum as my old 1/3hp pump. But one of the previous reviews on this page pointed me in the right direction: the outlet filter is much too restrictive. Removing it (the cap that houses it can be opened by undoing one Philips screw) fixed everything, and now I can achieve 50-100 micron vacuum instead of the 400 microns that my 1/3hp pump was limited to. I've observed no ill effects from running without any filter, but I'm sure it's a warranty killer.

I purchased this pump to do engine valve leak testing on my Ford 3.0 V 6 engine. The pump is high quality and It is easy to use, it got the job done with ease.
