ABSTRACT:
A coalescing filter for separating oil from a blowby gas stream includes a coalescing filter element designed with a plurality of relatively small flow-through pores which have the potential for creating a high restriction when wetted due to the surface tension which results. In order to reduce the restriction level, the coalescing filter is attached to a rotating component, such as a gear, so that rotary motion is imparted to the coalescing filter and centrifugal force is generated across the plurality of flow-through pores. By generating centrifugal force, any oil which might otherwise remain in said pores so as to clog the pores is spun out so that the pores of the coalescing filter element remain in a "dry" condition such that any restriction to continued flow is substantially lower than the restriction level when the pores are wetted.
