ABSTRACT:
A panel filter for removal of contaminants from a gas, the panel filter having at least one V-pocket formed of two halves, each half composed of multiple pleats of filter media. The pleats extend generally parallel, often at an angle of less than 5 degrees or even less than 1 degree, to the overall filtration path, so that air or gas to the filtered passes through the pleats in a generally straight manner, with minimal bends. Each pleat has two legs of different length. The panel filter provides improved dust collection and retention while restricting pressure drop.
