Abstract:
A filter assembly for filtering a fluid, said filter assembly including: i) a device assembly including an inlet flow duct and an outlet flow duct; ii) a casing open at an upper one end; said casing being tightly connected to the device assembly, and iii) a substantially cylindrical replaceable filter element fitted inside the casing, the flow from the inlet flow duct passing through the filter element, said filter element including an end flange disposed against an end of the filter element, said end flange having a circumferential, outer edge formed of plastic material and has a downwardly-bent edge portion disposed against an outer surface of the casing to provide a seal for the casing end, the outer edge of the end flange disposed against the upper end opening of the casing such that fluid pressure within the casing increases the strain on the seal, and at least one flow opening spaced radially inward from the circumferential outer edge which provides fluid communication between the inlet flow duct and an outer surface of the filter element.
