Optimum - Model GPB-Series -Bi-Component Polyolefin Filter

GPB-Series Bi-Component Polyolefin Filter Cartridges feature thermally bonded co- extruded polyolefin fibers manufactured in a unique and proprietary process. The result is fiber-to-fiber point bonds forming a rigid, fixed- matrix pore structure. The performance benefit of this construction is a sharpened retention size cut-off. Furthermore, the enhanced matrix rigidity provides greater tolerance to differential pressures. This unique feature also prevents changes in fiber matrix throughout the life of the filter. Consistent precise filtration acts to prevent against contaminant unloading. GPB series filter cartridges are free of additives, wetting agents, binders and silicone.
