Wound cartridges provide true depth filtration utilizing thousands of tapered filtering passages of controlled size and shape. Each layer of roving contributes to true depth filtration by trapping its share of particles.
These cartridges offer a gradual pressure increase during cartridge life unlike surface-type media that have an abrupt flow cutoff when loaded. The irregular outer layer reduces surface blinding, assuring longer cartridge life and larger dirt-holding capacity utilization.
