    摘要： A filter element according to the present disclosure includes a plurality of longitudinally extending pleats including outwardly radiating primary pleats and inwardly radiating secondary pleats, with at least one secondary pleat positioned between two adjacent primary pleats. Each primary pleat has a predetermined radial height, and each secondary pleat has a radial height that is less than the radial height of each primary pleat and different from the radial height of at least one other secondary pleat. A filter element according to the present disclosure provides greater filter area, an increased overall filter density, and access to more radial flow paths at the outer diameter of the filter element.

    摘要： An air filter device. The device includes a flat, closed top and an axially aligned open base larger in diameter than the top. Frusto conical filter media extends between the top and the base, the filter media having an axis aligned with the top and the base. An axially aligned, inverted cone extends from the flat, closed top toward the base.

    摘要： A filter comprising a filter case the interior of which is divided by a separator into upper and lower filtration chambers, a compact filter material of a cylindrical shape disposed in said upper filtration chamber so as to define on both outer and inner sides thereof a non-purification chamber communicating with upper suction ports formed at the upper part of said filter case and a purification chamber communicating with a drain pipe disposed on the upper surface of said filter case and having a large capacity, and a coarse filter material housed in said lower filtration chamber and serving also as a weight, said lower filtration chamber communicating with said purification chamber through passage ports formed in said separator while communicating with lower suction ports formed in a bottom surface of said filter case, said purification chamber communicating with an air feed port connected to an air pump.
