ABSTRACT:
An apparatus for adapting a paper towel filter to utilize a range of paper towel or filter element sizes. A perforated end plate is provided to engage the ends of the filter element. An inwardly sloped truncated conical extension from the center of the end plate extends into the ends of the filter element roll, which seats along the conical extension, based on its inner diameter. A pipe sealing face is provided along the inner surface of the conical extension, at the end away from the end plate; this face sealingly encloses an axial pipe. The combination of two end plates, so mounted on an axial pipe, and enclosing a paper towel roll, forms a removable filter cartridge for a paper towel filter, which readily adapts to a variety of sizes of paper towel rolls.
