Abstract
A filter element includes a media pack of Z-media having first and second opposite flow faces and a side wall extending between the first and second flow face. A gasket is secured to the side wall. The gasket has a sealing portion and an attachment portion. The sealing portion has a flat surface at least one inch long and is located between being planar with and 0.5 inches recessed from the first flow face, inclusive. The filter element can be used in a dust collector.
Claims9
A method of installing a filter element into a dust collector;
- the method comprising:
- (a) providing a dust collector having a housing including an enclosed interior volume within the housing, a dirty air inlet defined by an opening in a wall of the housing configured for taking in a flow of unfiltered air into the interior volume of the housing and a clean air outlet in the housing configured for expelling a flow of filtered air from the interior volume of the housing;
- the dust collector having a tubesheet in the interior volume having a plurality of openings;
- the dust collector having a plurality of blowpipes to direct a fluid pulse at a planar downstream flow face of a filter element;
- each of the blowpipes having a center longitudinal axis and being oriented relative to a plane containing the tubesheet openings such that a centerline of the fluid pulse from each blowpipe is aligned with the longitudinal axis of each blowpipe and is at an angle non-orthogonal to the plane and not in line with a direction of filtration flow through the filter element;
- and
- (b) positioning the filter element in the interior volume of the housing of the dust collector by orienting the planar downstream flow face of the filter element in one of the openings to be even with or less than 0.5 inches recessed from the tubesheet.
