TANGENTIAL AIR CLEANER WITH COILED FILTER CARTRIDGE

Filtration systems having a tangential air cleaner having a coiled media filter element and a cyclonic pre-cleaner are described. An outer wall of the filter element acts as a pre-cleaner sleeve of the housing to generate a cyclonic flow of the intake air prior to the intake air being filtered by the filter element. The housing cover includes geometry that redirects the cyclonic low from a tangential path to an axial, straight-through flow directed through an inlet flow face of the filter element. Various embodiments of such filtration systems offer increased filter performance and capacity compared to similarly sized cylindrical pleated filter elements having a radial flow filtering path.
