String wound filter cartridge filters are manufacturedusing a high speed, continuous wind process which creates a superior one-piece filter with hundreds of diamond shaped tunnels that get progressively smaller from the outer diameter to the core. Finer particles are progressively trapped as fluid travels to the center of the filter which allows for a much greater retention capacity than straight surface filter media of the same dimensions and porosity.
The 10" and 20" string wound filters have a unique dual density that is superior to most string wound filters.The filters are wound at high tension for the first half of the winding process and then at a lower tension during the second half of the wind. This produces a superior and efficient filter that does not blind as quickly, thereby giving longer filter life with better filtration without compromising efficiency.
The winding pattern provides 3.5 square feet per each 10 inches of cartridge length. For each 10 inch filter length there will be approximately 0.5 to 1 pound retention of solids before replacement becomes necessary. The amount of solids retained depends on the type of solids in the solution as well as the head pressure developed by the pump.
String wound filters canbe custom madefrom 4" to 72" in length and from 2" to 5" in diameter. We can satisfy your filtration needs by producing filters with filtration capabilities from 0.5 microns up to 400 microns.
