Gopanis String Wound filter cartridges are backed by years of filtration experience combined with state-of-the-art manufacturing technology and a well-equipped test laboratory.String Wound cartridge filters are manufactured using a continuous winding process that creates a superior high performance 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 cartridge allowing for much greater retention capacity.String Wound cartridge filters offer true depth filtration with high flow capacity, less pressure drop and extremely low media migration. Because of specially designed winding patterns and controlled density these cartridges have high dirt holding capacity which results in longer life, less downtimes and savings in labor/replacement cost.Availability of these string wound cartridges in various combinations of media and core material make them ideal for use with many chemical applications and temperature demands. String Wound filter cartridges are an excellent choice as pre-filters to protect expensive downstream filtration equipment.
