Cartridge Filters Manufacturers

Cartridge filters are designed to collect the suspended solids found in the water on the outside of the filter cartridge or on the largest surface area of the filter. The medium used in this type of filter is a cartridge made of fine-mesh, pleated fabric. Water enters the metal or fiberglass filter canister and flows over the cartridges. A tight mesh of this fabric strains impurity out of the water before water is forced into the center of the cartridge, finally leaving the unit through plumbing at the base. Cartridge filters are classified by square footage of filter surface. By pleating the cartridge material, a great deal of square footage can fit into a very small package. Typically cartridge filters for residential spas range from 20 to 120 square feet in a tank not more than 4 feet high by 11/2 feet in diameter.
