Filter cartridge, dust collectors, and methods

摘要

An air filter cartridge has Z-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. A method of servicing includes orienting the air filter cartridge against a guide ramp and moving the filter cartridge until the side gasket member is engaged against the tubesheet sealing surface.

主权项

1. A dust collector comprising:
(a) a housing having a dirty air inlet, a clean air outlet, a tubesheet, and a frame arrangement;
(i) the tubesheet separating the housing between an unfiltered air plenum and a filtered air plenum; the tubesheet having a plurality of apertures therethrough; the tubesheet having a sealing surface;(ii) the frame arrangement extending from the tubesheet; and (b) a first air filter cartridge having a gasket arrangement removably installed in the housing, the first air filter cartridge including 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;
(i) the media pack comprising a stack of strips, 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, the facing media sheet being a flexible non-woven fibrous material; (c) a lift assembly connected to the housing; and (d) a cartridge holder tray held on and slidable relative to the lift assembly;  the first air filter cartridge oriented on the cartridge holder tray.
