fitting. To use the gas ballast, start the pump and open the gas ballast valve until the system has reached 1000–3000 microns. Close the valve to allow the pump to pull down to its ultimate vacuum level. The gas ballast valve may be opened or closed at any time during pump operation. It is fully open at two turns counterclockwise.

The use of gas ballast in rotary vane vacuum pumps- Vacuum .

The ballast valve can accelerate the extraction of steam without polluting the oil. If the rotary vacuum pump only pumping permanent gas, the gas does not liquefy due to the increase in pressure, so there is no deterioration of the pump oil. However, if the pump is used to vacuum dry or pumping humid air, the gas will have not only permanent gas but also Water vapor, if this portion of water .
