The WFMBR melt-blow cartridge with 20 % recycled content is manufactured in the melt-blow process whereby four different spray nozzles are used to combine fine and coarse continuous fibers to form a multilayer structure. The fine layers are situated on the inside of the depth filter structure; the coarse layers on the outside. Due to this four-level gradiation coarse particles are retained in the outer layers and finer particles in the inner layers. This construction ensures a long service life, high dirt-retention capacity and low differential pressures.
The WFMBR melt-blow cartridge can be delivered optionally with open ends on both sides or with the standard adapter constructions.
