Review on FavorCOOL 2FC-36T 2-Stage 1/3HP Rotary Vane Vacuum Pump for HVAC Car A/C Refrigerant Charge - R410a R134a R22 by Kevin Hauck

so it works great and looks great. Also, it's built like a tank. I compare it to the more expensive Robinaire brand and it works just as well but sounds very different. Compared to Robiners, the engine sounds unhealthy. It's like listening to a '69 Corvette and then comparing it to a 2020 Hyundai. So it's louder than the Robinaire and gets hotter (see photo), but does the job and is very good value. It's also two-stage, so it can create deeper vacuums. Definitely recommended as an inexpensive vacuum pump.
