ABSTRACT:
This invention relates to a pleated high efficiency particulate air filter and separators therefor in which the separators comprise a lattice with flat or rounded 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, and to eliminate sharp edges and corners which would tend to injure the media under compression.
The separators may be formed of plastic by molding into a single unit or into multiple segments which may be joined side by side to provide a desired separator length. The structure permits enclosure and bonding of the assembled pleats and separators with the end portions of each encased by a bonding material.
