I have used this pump twice so far, and it works very well. Pulls the system down very quickly due to the large displacement, so it doesn’t have to work hard to get the job done. I am using it for automotive ac and that required a different fitting than the one that came on it, also found that on Amazon. The 11.5 CFM Single Stage Vacuum Pump comes with a bottle of oil, I did not know this and ordered a bottle of oil, still not a bad idea as you should change the oil often for best performance.

We use the vacuum pump to apply a vacuum to our 1′ sq vacuum chamber used for silicone moldmaking and resin casting business. This is a solid R410a Manifolds Gauge and has held up well with daily use.

The R134a Manifolds Gauge capacity was the real selling point, as time is important due to the short work cycle of the materials we use. This pump gets us down to 28.5″ in a hurry!
