Abstract
A tubular filter arrangement (1000) comprising a tubular filter element (100) and a tubular air pulse distributor (300) is provided. The filter element comprises a tubular pleated filter media (106) having an initially circular cross section, and a cage structure (120) and which along an exterior envelope surface thereof is arranged to support the pleated filter media. The exterior envelope surface of the cage structure, defines a first and a second set of two opposing wall portions (123, 124). In a condition when the pleated filter media is arranged to encircle the exterior envelope surface of the cage structure, an inner wall (107) of the pleated filter media is elastically deformed to conform to the exterior envelope surface of the cage structure (120). The tubular air pulse distributor comprises a locking member (303) configured to allow the tubular air pulse distributor to lockingly engage the tubular filter element.
