VEVOR 3.5 CFM Vacuum Pump, 1-Stage HVAC Vacuum Pump with Oil, AC Vacuum Pump 134a, 4-Pole Pure Copper Motor-Longer Running Time, for Resin Degassing, Refrigeration Maintenance, Vacuum Package etc.

Originally had another one, but it didn’t seem to be working right and was blowing lots of oil out of the exhaust. Got this one and have used it quite a bit, seems to do a great job.

I was expecting this to work fine, and it does. I was hoping it would go below 500 micron so I could meet the specs for installing a mini-split. I was surprised that with new oil and a short line, this thing will pull a vacuum down to less than 50 microns. It's quiet, and it works, and it doesn't get too hot.I have no idea how fast it is, or how long it might last, but out of the box it absolutely works fine. Make sure to fill with oil to the right spot and keep the oil level up or you'll wreck it, like any other pump that requires oil.

worked great for my one time use on auto and saved me at least a few dollars.would be good for home use or small shop.

Fairly solid product. I used this to effectively pull a vacuum on my car air conditioner system. It held a vacuum.

Works well, but (despite the product description) the threads were metric, not imperial.

Excellent pump

For the price it's great. It's not my main vacuum pump, but I've used it to pull several hvac systems down to 500 microns with no issues so far. Would definitely buy another.

Someone else’s review said the 5 CFM pump is a beast. I agree 100%. It runs quiet and drew a vacuum very quickly. Ran it for 45 minutes straight in hot weather and it didn’t miss a beat. I have ice cold AC again after replacing a leaking condenser.
