Dust collector and method of servicing the same

摘要

An air filter cartridge has Z-media (322) and a gasket arrangement(341, 342) with a perimeter gasket member (341) against the downstream flow face and a side gasket member (342) adjacent to at least a partial extension of a first side panel (336). The side gasket member (342) includes no portion against second, third, and fourth side panels (337-339) 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 (341) 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 (342) is engaged against the tubesheet sealing surface.
