Patent

CA 2115294

A high velocity air filter includes a hollow, generally cylindrical filter element comprised of a filtering material folded to extend back and forth between inner and outer peripheral surfaces to define a series of pleats extending longitudinally of the filter element. The inner edge of a plurality of the pleats is a lesser distance from the longitudinal axis of the filter element than the inner edge of the other pleats, thereby forming a plurality of short pleats and a plurality of long pleats. The inner diameter of the filter element is less crowded than in conventional high velocity air filters. The restriction to airflow is thus lowered without increasing the surface area of the filter media or sacrificing the capacity of the filter element.
