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. The elements are usable in a dust collector having a dirty air inlet, a clean air outlet, and a tube sheet dividing between an unfiltered and a clean air volume. An element is removably mounted and sealed within the tube sheet. 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. An axial force is exerted to form a seal between the gasket member and the tube sheet.

Claims8

Dependent claims

A panel-style filter element comprising:

(a) a media pack having first and second opposite axial ends and a side extending between the first and second axial ends;
and
(b) a gasket member adjacent to the side;
the gasket member including first and second gasket regions separated by a channel;
(i) the first gasket region being nearer the media pack than the second gasket region;
(ii) the channel being an open volume between the first and second gasket regions and including:
(A) a length of at least 0.3 inch as measured from an end of one of the first and second gasket regions;
and
(B) a width of at least 0.15 inch as measured between the first and second gasket regions;
(c) the gasket member further including first and second opposite axial gasket regions;
(i) the first axial gasket region being adjacent to the first axial end of the media pack;
(ii) the second axial gasket region defining the channel;
and
wherein the gasket member defines at least one protrusion-receiving hole, the at least one protrusion-receiving hole being a through hole.
