New Position 5.0 CFM 1/2 HP Dual Stage 0.3 Pa Rotary Vane Vacuum Pump for HVAC, Air Conditioner Refrigerant,Food Packaging,Milking,110V

I purchased (3) of these pumps for my HVAC techs because of the price point.My techs are reporting back that these vacuum pumps are not performing as needed.1) pump will trip on internal overload if left to run for more than 45mins.2) after less than a 3 weeks in use, pump would not pull down to 500 microns.... oil was also changed with no improvement.3) I believe these pumps are better suited for the small appliance/auto trade and not for larger capacity residential/commercial HVAC

La use en mi trabajo y no sirve.

I literally set up a refund within the same night I opened the box. I’m very familiar with vacuum pumps, put oil in correctly, turned on and couldn’t be near this thing because of the high pitched grinding noises coming from it… any QC would have experienced the same

La bomba hace buen vacio, pero se caliente a los 10 o 15 minutos funcionando y se apaga, ya no vuelve a prender hasta que se enfría.

está buena. funciona bien .buen precio .es pequeña.no pesa mucho. la envían desde EU. te piden clave para entregártela. cambia todos los días la clave .es un gorro .el mensajero dio como 4 vueltas por lo de la clave. pero valió la pena todo el show.👍
