Membrane Filter Cartridges


Dewdon’s string wound cartridge filters provide true depth filtration, high dirt holding capacity, and extremely low media migration. They are a superior, one-piece cartridge manufactured using a high speed, continuous wind process, and are available in a wide variety of lengths and porosities.

Especially significant is the availability of filters in an almost endless combination of media and core material, to handle virtually any chemical and/or environment or temperature. Our string wound filter cartridges are available with 14-string, seven core and 12 material and end cap options. Outside dimensions of 2 to 6 inches and lengths of 5 to 72 inches are standard. They can be sized for virtually all single- or multi-round filter housings. The precise winding pattern defines micron ratings and results in higher dirt-holding capacity and efficiency.
