Review: I had no issues with the pump. It sucked my honda civic system down to-30 very quickly. Ran pump for almost 1 hour straight with no overheating or cutting out. I will say it was 50 degrees outside when I used it. Pump makes some strange sounds when running however it did a great job. After 10 minutes or so the pump was not putting out any mist. The way I understand the manual once mist stops them moisture should be out of the system. The oil that's included was a little more than needed to fill the pump so I have extra if ever needed. Good pump for the occasional users.
Review: I use this for degassing silicone and epoxy when casting or molding objects. Works great. I use a pair of vacuum chambers, a 3 gallon and a 10 gallon, either individually or hooked up at the same time. Getting vacuum hoses is actually pretty tough - there's very little documentation about what types of fitting are the right ones for vacuum use, which ones are compatible with which others, which ones have nice quality of life features like swiveling, and which ones leak unless used with sealing grease. That's not the pump's fault though.

## Questions & Answers

**Q: How many microns can this pump do?**
A: The seller is saying 40 micron, but the description says 150 . . . I wonder which it is? That is nearly a 400% difference.

**Q: What is the warranty?**
A: One year warranty. please refer to www.kozyvacu.com website for details

**Q: What is needed to pull an R12 AC system**
A: This will work on r12 or r134a.

**Q: does it have anti-siphon valve in event power to pump is disrupted?**
A: The seller must not know but this has NO CHECK VALVE, NO ANTI SIPHONING. Trust me, I've used this several times and I like to put mine on a timer. I found out the hard way. A bunch of oil spilled back in my vacuum chamber and lost over $500 worth of product. Kozyard LLC must not care that people use these things on equipment that will cost a lot of money if they tell us a bold face lie.

Re Kozyvacu 5CFM 2-Stage Rotary Vane Vacuum Pump I've used this pump a few times to pull a vacuum for cars A/C. I found it to be efficient and surprisingly quiet. It pulled the maximum vacuum within a matter of minutes. I have left it on for about 1/2 hr with no problems (it obviously got a little hot as expected). Build quality seems fine. Other folks have mentioned the oil mist from the exhaust. I can't comment on if this is normal for vacuum pumps but knowing it may do this I connected a length of pipe to direct the exhaust. This issue wasn't a problem to me. (Note, I chose the 2-stage, 5 cfm model)
