Description
DESCRIPTION
Molded polypropylene or cellulose filter cartridges have a fibrous structure that provides depth filtration through the gradient density depth structure. These filters are capable of capturing a wide variety of different sized particles. Molded cartridges rely on the depth of the filters to gradually filter out unwanted particles and sediment. Particles are retained and become trapped in the matrix of the media, a permeable material used to separate suspended particles from liquid. All of these cartridges are available standard without need of a center core support tube. Some of these cartridges are available with the reinforced core tube as an option. Molded Polypropylene Filters: These cartridges are also known as spun-woven or melt-blown filters and have a fibrous structure that provides depth filtration by using a gradient density depth filter. The fibers are locked in place with a thermoplastic binder. Annular (ringed) grooves are sometimes used to increase dirt loading capacity. Molded Cellulose/Melamine Resin Filters: Like molded polypropylene, these filters have a fibrous structure manufactured using a felting process to generate a gradient density depth filter. The fibers are locked in place with a thermoplastic binder. Annular (ringed) grooves are sometimes used to increase dirt loading capacity.
