How does the oil mist separator work?

 2021-06-15 | View:71

The oil mist separator is composed of a side channel blower and a filter housing containing filter elements. The side channel blower generates a negative pressure in the filter housing, and air containing oil mist is sucked into it. The filter element is specially designed for purifying exhaust gas. The disposable filter element containing ultrafine fiber can provide better filtration efficiency under extremely low pressure drop, and the void (pore) volume is more than 90%, with open pore quality and very long service life. These elements are self-sealing and can be easily sealed into the housing by axial compression with integrated special tie rods.

The air flows into the cavity in the filter housing through the intake column tube and flows to the filter element. Here, the fine oil droplets in the air remain in the element, and the air flow brings them to the surface. The special two-layer structure consists of an integrated supporting inner layer sandwiched between two bound outer layers. This design provides excellent burst strength, optimizes the coalescence of droplets, and ensures long-lasting and efficient removal of oil mist. Since the filter element is composed of multiple layers, it can prevent the extracted oil mist from blowing back through the element. The oil separated by the filter element flows along the outer surface of the filter element to the bottom of the housing. It is collected in the annular space around the bottom of the filter. From here, the purified oil is delivered to the oil tank through the oil outlet and the connected oil hose. The inorganic components of the filter element are completely inert to all lubricating substances and can resist almost all chemical substances in the air.
