Review on 💨 Robinair (15310) VacuMaster Single Stage Vacuum Pump - Efficient 3 CFM Power for Superior Performance by Chase Cooper

The pump has worked great so far. 500 micron vacuum on each of my two mini-split systems in about 15 minutes. Comes with enough oil for 1 filling plus approx. 4 oz. The only complaint is that the packaging was terrible. The manufacturer's box was placed in a shipping carton without any padding. The 1/4 lid was worn through the inner box and the styrofoam in the original box was crushed. I was very concerned that the fitting was damaged but upon closer inspection everything turned out to be fine. The hat was all dirty. All in all a good buy. It feels very sturdy and works great for me.
