Review: Good pump for occasional use. - 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: Works on my freeze dryer - I bought this as a backup vacuum pump for my Harvest Right freeze dryer. The pump failed and I replace it with another Harvest Right pump. That pump failed after two runs and was returned. So, I put the Kozyvacu pump into service. It's worked like a champ ever since. I did have to run to Napa to get fittings to make it work with Harvest Right. The new fittings required removing the check valve which means you need to operator the Harvest Right the way you would if the HR vacuum pumps check valve fails (which is a very common occurrence). Pros: 1) Price 2) It works. It gets a small HR to 500mTorr in 4 minutes and a medium HR to 500mTorr in 8.5 minutes. 3) It's much lighter than either the JB or HR vacuum pump. Cons: 1) No check valve 2) Draining the oil for filtering is messier than with either the JB or HR pump. 3) It vents oil vapor on startup. Less than my JB ever did, but more than an HR pump 4) You must buy additional fittings (Napa has them for $12) 5) Works on both my small and medium HR freeze dryers. I don't know how long lived it will be but I'm about 6 months into owning a HR (a small from HR and a medium that was a derelict I found on Craigslist) and I’ve gone through 2 vacuum pumps. The JB with the Craigslist machine was a basket case to begin with, the new HR is still functioning but a backup HR I bought failed after 2 uses. I’m happy with how the Kozyvacu pump works, but it’s not perfect and requires a small amount of disassembly to add the correct fittings. But otherwise it’s a great value and seems robust so far.

## 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.

### ⭐⭐⭐⭐ Quiet Vacuum but spews oil
*by T***O on January 30, 2019*

I am using this to pull vacuum on vacuum bags for carbon fiber resin infusion. The manual notes that you're suppose to let the pump run through a break in period. I let the pump run for about 30 minutes before I shut it off and drained the oil out of it. I also bought vacuum pump oil with this pump because I did not know that it comes with a bottle of oil to fill the pump back up after the break-in period. I had some trouble getting the oil to show in the sight glass but a little rocking back and forth fixed that. This pump spews oil fog constantly while running. The first time I really used this I had it running for 7 hours straight. It had no problem with this. Other than the fog of oil that filled my garage it pulled more than 30 In/Hg the entire time (my gauge only goes down to 30, but it was past the 30 mark onto the stopper). This machine will not hold vacuum when you turn it off. You will need to clamp the lines or install a ball valve. I did not know this initially and I turned the pump off to inspect a bag. About 10 minutes go by and I notice oil in my resin catch can. The vacuum in the bag had sucked oil back up through the hose. Luckily I had a catch can in-line so no oil was sucked into my composite piece. Overall for the price this vacuum is hard to beat. I have more than 12 hours of run time on this with two fairly long stints. The vacuum didn't get hot during either of them and ran like a champ the entire time. I need to figure out a way to either filter the oil out of the exhaust or re-condense it, but otherwise it's worked well so far.
