Abstract
According to one aspect of the present invention, a filter assembly for removing particulate matter from a fluid stream is disclosed. The filter assembly includes a filter medium having a number of longitudinally extending spaced pleats. Opposing faces of adjacent pleats form a valley therebetween and include a pair of peak portions and a valley portion. The filter assembly further includes a plastic support net being pleated for supporting the filter medium in a pleated shape. The plastic support net includes spaced strands extending in a first direction and spaced strands extending in a second direction that is generally transverse the first direction. The strands extending in the first direction continuously extend over the valley and peak portions of opposing faces of adjacent filter medium pleats and are aligned in a direction substantially perpendicular to the longitudinal direction of the filter medium pleats.
