    2.4 Structure (Refer to Fig. 3) The gas discharged from the oil sealed rotary vacuum pump (air, nitrogen gas, etc.) blows up the oil in the pump and is introduced to the oil mist trap along with fine particles of oil blown up. These fine particles of oil (oil mist) are trapped by the filter element when they pass through it and the condensed large oil particles gather between the oil mist trap and the filter element and are discharged through the oil return port.
