All the oil sent from the oil pump is filtered and then fed by pressure to the engine`s main body.

Requires a small installation space since the filter is used alone in most cases.
Currently, most widely used for gasoline-powered vehicles.
Uses an appropriate filter element that enables maintenance of the oil pressure required for the engine and effective filtering of particles that may wear the engine.

This filter type is widely used for diesel-powered vehicles.
The bypass filter is used to eliminate carbon dirt and particles that cannot be caught by the full flow filter. For this, pores on the filter element are made smaller. As a result, resistance of oil pressure in the bypass filter is higher compared to that in the full flow filter, taking more filtering time.
