Filter Cartridges
Unlike conventional string wound cartridges (right insert), our true graded density Polymicro™ cartridges (left insert) offer maximum dirt-holding capacity for longer filter life.
These polypropylene micro fiber cartridges are available in standard and custom lengths and diameters with ratings from 1 to 100 microns. Sealing options include standard DOE, DOE w/gaskets, SOE-222, and SOE-226.
We also offer a full line of Polywound conventional string wound cartridges in a variety of materials. Polywound cartridges are available with core materials of polypropylene, tinned steel, 304 stainless steel, or 316 stainless steel.
