Abstract
A filter has a longitudinal axis with an inner diameter defined by a hollow longitudinally extending center. The filter has fingers extend radially outwardly arcuately from the longitudinal axis. The fingers have base ends near the longitudinal axis and outer edges at extremities spaced from the longitudinal axis. The outer diameter of the filter is defined by the outer edges of the fingers. The filter is formed from a sintered porous molded thermoplastic or another material resulting in a filter more rigid than standard filters. The fingers are spaced apart from one another a predetermined, substantially fixed distance to form slots therebetween sized to capture contaminants therein.
