Customer Reviews for VEVOR 1/5 HP Single Stage Vacuum Pump, 3.5 CFM, 120V AC Air Conditioning Conditioner Vacuum Pump, 1/4" SAE Male 1/2" ACME Male Inlet, for HVAC Repair, Refrigeration Maintenance, Resin Degassing

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.

This pump is actually really well made. I had an issue with a stuck vane at first. My son figured it out. We also changed out the oil for a thinner consistency (I think our elevation had something to do with this idk). It runs perfectly now. We use it on our milk line. I’d definitely recommend

Very quiet operation, quick to pull vacuum on system. Very satisfied quality unit, highly recommended

For what its worth, the pump performed well. It pulled down to about 150 microns after 30 minutes using the Vevor refrigerant recover tank. The included exhaust filter had to be discarded because it blocked airflow. The air filter would pressurize and pop off the air filter housing cover. I replaced it with a copper scrubing pad to filter some of the oil vapor. I will only use this pump for my own hobbies and infreqent AC repairs.

This pump works well and is much lighter than my old one. I have used it multiple times with no issues

just good for the price love it....................................................................................................................................................

Comes with vacuum oil. I've used this vacuum pump on several tractors, will pull down to 30 inches no problem. We'll worth the money.
