2. GENERAL DESCRIPTION
2.1 Features
(1) Removal of oil mist with high efficiency
Approx. 90% of the oil mist discharged from an oil sealed rotary vacuum
pump can be removed, allowing the work environment to be kept free from
contamination with oil mist.
(2)
Employment of cartridge type filter element
The cartridge type filter element can be easily replaced when it is clogged or
corroded.
(3)
Pump internal pressure relief valve
If the filter element is clogged, the pressure in the pump will rise at start-up
of the pump or during pumping operation, which can be dangerous.
If the pressure in the pump rises above 0.03 MPa (0.3 kg/cm
2
) (gauge
pressure), the pressure relief valve will be activated to prevent the pump and
oil mist trap from being damaged.
