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.
Gas from which most part of the oil mist has been removed is discharged
through the exhaust port of the oil mist trap.
