Abstract

A filter element includes a media pack and a gasket member. The gasket member includes first and second gasket regions separated by a channel. One or more filter elements are usable in a dust collector. One example dust collector includes a collector housing having a dirty air inlet, a clean air outlet, and a tube sheet dividing the housing between an unfiltered air volume and a clean air volume. At least one filter element is removably mounted and sealed within the tube sheet. A gasket member secured to the element includes first and second gasket regions separated by a channel. At least one projection angled relative to a plane of the tube sheet extends into the channel of the gasket member. A method of servicing a dust collector includes removing a first filter element from the tube sheet in the housing, and then sealing a second filter element against the tube sheet by orienting at least one projection extending from a plane of the tube sheet into a channel defined by a gasket member secured to the second filter element. Next, an axial force is exerted against the gasket member to form a seal between the gasket member and the tube sheet.
