Bestauto Vacuum Pump 6CFM Dual Stage Refrigerant Vacuum Pump 1/2 HP HVAC Rotary Auto Refrigerant Vacuum Pump, Air Conditioner Refrigerant HVAC Air Tool for Automobile Reparation Vacuum Evacuation

First time I use it my 20 amp braker blew. Reset the braker and the pump overheated and stopped working. After it cooled down it would overheat everytime. Don't buy this pump.

Good product for the price. Works well. Easy to use.

I used this pump for wood stabilization. It pumped for 72 hrs. straight, minimal noise, holding -24 @7,000 ft. elev. No problem
