Review: Outstanding!! - I read reviews for a hand full of these pumps before purchasing and was worried about a hand full of things. I have done plenty of automotive A/C jobs and got tired of dealing with rentals or an air compressor venturi attachment. I decided to treat myself and bought this to make life easier. It works great and bottoms out the manifold gauges within a minute or two to boil off any moisture. I kept it on for 45 minutes and was all worried about oil clouds and misting etc, but this did not make any mess at all, nor use any oil at all. Maybe it was the environment, I’m not sure. For reference this was in Southern California and 82 degrees outside. It’s true the provided bottle of oil that comes with this is only enough to fill the tank half way to its capacity, but since it didn’t consume any oil for the job I am still good for the next one. This pump is whisper quiet as well, so I was able to talk normal around it running with no issues and the neighbors can’t complain. The casing was hot to touch as expected, but not enough to burn at all. Build quality is exceptional, including the plastic port caps. I was worried those would be brittle and thin, but they are heavy duty. No leaks at all either, and will update if I have any issues. Overall, just a great purchase!
Review: Great vacuum pump for AC maintenance. - Second Orion product I’ve bought and both have been quality tools. The pump came with oil, I filled it and put it to use. It works perfectly and I like the fact that it has both common size fittings on the pump. It also was a great value!

### ⭐⭐⭐⭐⭐ Worked great when I replaced the AC compressor in a tractor
*by K***E on August 30, 2025*

I used it to vacuum the AC system in a Kubota tractor when I replaced a bad compressor. Worked great it had no issues vacuuming the system for an hour strait in 100 degree weather. I had my work fan blowing on it and it got pretty hot to the touch, but that did not seem to bother it. My cheap basic Vector brand manifold set fit it just fine. Seems like a good pump and it has already paid for itself with just the one repair and now I will have it for the next time an AC goes out on something.
