Review on 💨 Robinair (15115) VacuMaster Single Stage Vacuum Pump - For Efficient Single-Stage Vacuuming, Delivers 1.5 CFM by Peris Auditore

I've used this on two different cars after repairing the air conditioning compressors in both so it's already paid off! This quickly creates a deep vacuum that is very close to 30 inches of mercury. Run it for 10 to 20 minutes and charge it again. Both machines are still blowing cold. The unit came with oil and a few small adapters to connect it to the A/C manifold and it runs fairly quietly. I would buy it again if I needed a different vacuum pump for anything.
