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

Removed from the box, filled with the supplied oil and switched on. After 10 seconds the thermal switch tripped. Repeat more than 20 times. It smelled funny when I opened the box and I seriously wonder if anyone else got it back after running it oil free with a DIY mini split rig. Spring. Since it was too late to return and I had to collect the pump locally to complete the installation, I will limit and write off my losses.
