How many microns can this pump do?

The seller is saying 40 micron, but the description says 150 . . . I wonder which it is? That is nearly a 400% difference.

What is the warranty?

One year warranty. please refer to www.kozyvacu.com website for details

What is needed to pull an R12 AC system

This will work on r12 or r134a.

does it have anti-siphon valve in event power to pump is disrupted?

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.
