    Abstract: A method of cleaning a filter element includes directing a jet of pressurized gas from a nozzle onto a filter element, with the jet having a non-round cross-sectional shape that is a same general cross-sectional shape as the opening in a tube sheet holding the filter element. The nozzle has a channel for the pressurized gas that is obstruction-free. A method of designing a nozzle arrangement for directing a jet of pressurized gas onto a filter element includes designing a nozzle arrangement to generate a jet of pressurized gas having a non-round cross-sectional shape that is a same general shape as a non-round shape of an aperture in a tubesheet holding the filter element. The nozzle arrangement includes at least one nozzle, each nozzle has an unobstructed flow channel, and each nozzle is cylindrical in shape and has at least one open slot. A pressurized gas generator includes a compressed air manifold storing pressurized gas, a valve in fluid communication with the manifold, and a nozzle arrangement. The nozzle arrangement includes at least a single nozzle connected to the valve. Each nozzle has either a cylindrical wall or a lobed wall and defines an interior channel. The interior channel is obstruction-free. The wall defines at least one open slot.

    Abstract: To improve in pulse cleaning of filters, 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. A dust collector includes a housing with a dirty air inlet, a clean air outlet, and an interior; a tubesheet in the housing interior having a plurality of openings; a plurality of panel-style filter elements mounted in a respective one of the openings in the tubesheet; and a plurality of blowpipes, with each being oriented to direct a fluid pulse at a respective one of the panel-style filter elements. The filter elements include a media pack of Z-media, a gasket that is between planar with and 0.5 inches recessed from the first flow face, in which the gasket forms a seal with the tubesheet. The blowpipes direct a pulse at an angle that is not normal to a plane of the openings in the tubesheet and not in line with a general direction of filtration flow through the filter element. A method of cleaning a filter element installed in a dust collector includes providing a filter element and periodically pulsing a jet of gas into the downstream flow face to cause at least some particulate material on an upstream side of the Z-media to be removed from the Z-media.
