How often does the oil need to be washed?The Pump can be operated for 12 hours at a time?
Dear Customer,
The oil should be replaced when it changes color. There’s no fixed interval, as this depends on the frequency of use and the operating environment.
Kindly note that the pump cannot operate continuously for 12 hours as the oil will deplete, and the pump must be stopped to refill the oil.
Thanks,

which type of oil should be used to avoid damaging it
Dear Customer,
For this vacuum pump, oil with standard viscosity of 68 is sufficient. If you prefer a higher quality option, you can use oil with a viscosity of 100.

In the description you write "Flow Rate: 5 CFM (142L/min, Max Power: 1/2 HP, Ultimate Vacuum: 0.3 Pa, Voltage: 110V". The mentioned ultimate vacuum (0.3 Pa) differs from the one mentioned in the comparison sheet (two stage vs one stage) where for the two stage pump 10-15 Pa written. Which number is correct?
Dear Customer,
Thank you for pointing this out. The correct ultimate vacuum for the two-stage pump is 10-15 Pa. We’re updating this information immediately.
