High efficiency particulate air filter and separators

摘要

This invention relates to a pleated high efficiency particulate air filter and separators therefor in which the separators for filter media to be wound therearound comprise a lattice with tapered struts or spacers, a rounded pleat fold contacting member, and vertically spaced apart air inlet and outlet media supporting flat members to provide uniform internal support for the pleats. The struts are formed to provide a tapered space between filter media and the struts after the media is wound around the separators.
