Abstract
An air filter cartridge has filter media and a gasket arrangement with a perimeter gasket member against the downstream flow face and a side gasket member adjacent to at least a partial extension of a first side panel. The side gasket member includes no portion against second, third, and fourth side panels of the air filter cartridge. The air filter cartridge can be used in a dust collector having a tubesheet and a frame arrangement extending from the tubesheet. The perimeter gasket member seals against the frame arrangement and the side gasket member seals against the tubesheet.
Claims19
An air filter cartridge comprising:
- (a) a media pack having upstream and downstream opposite flow faces, first and second opposite sides extending between the upstream and downstream opposite flow faces, and third and fourth opposite sides extending between the upstream and downstream opposite flow faces;
- the media pack comprises a stack of strips of single facer filter media material, each strip including a fluted media sheet secured to a facing media sheet and oriented with flutes of each fluted sheet extending in a direction between the upstream and downstream flow faces;
- (b) a first side panel against the first side of the media pack;
- (c) a second side panel against the second side of the media pack;
- (d) a third side panel against the third side of the media pack;
- (e) a fourth side panel against the fourth side of the media pack;
- and
- (f) a gasket arrangement including:
- (i) a perimeter gasket member against the downstream flow face and around a perimeter of the downstream flow face;
- and
- (ii) a side gasket member, adjacent to at least a partial extension of the first side panel;
- the side gasket member including no portion against the second, third, and fourth side panel;
- (A) the side gasket member extends against the first side panel from the downstream flow face a distance no greater than 40% of an overall length of the first side panel;
- and
- (g) a handle secured to the cartridge.
