1. The working pressure of oil-free rotary vane vacuum pump should meet the limit vacuum and working pressure requirements of vacuum equipment. For example, a vacuum adsorption process requires - (60kPa~90kPa) working vacuum, and the limit vacuum of the selected oil-free rotary vane vacuum pump should be at least - 90kPa, preferably - 93kPa. Generally, the limit vacuum degree of the selected pump is half to one order of magnitude higher than the working vacuum degree of the vacuum equipment.

2. Under its working pressure, the oil-free rotary vane vacuum pump should be able to discharge some gases generated in the process of vacuum equipment.
