Abstract

A filter holder for a filter element that has an oval-shaped cross section transverse to a longitudinal direction thereof, the filter holder including: a receiving section configured to receive the filter element; fluid inlet for allowing fluid to be filtered into the filter holder; fluid outlet for letting the fluid filtered out of the filter holder; the fluid inlet is arranged so the inflow direction of the fluid to be filtered into the fluid inlet is parallel to the longitudinal direction of the filter element; the fluid inlet has a guide member configured to deflect the fluid as it flows into the fluid inlet such that it flows around in a spiral in the filter element that can be received in the receiving section in order to separate particles contained in the fluid to be filtered on a wall of the receiving section with the aid of centrifugal force.
