GPB Series Depth Filter Cartridges
GPB-Series Bi-Component Polyolefin Filter Cartridges feature thermally bonded coextruded polyolefin fibers manufactured in a unique and proprietary process. The result is fiber-to-fiber point bonds forming a rigid, fixedmatrix 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.
Typical Applications:
- Paints and Coatings
- High-purity Inks
- Resins
- R.O. Pre-Filtration
- Food and Beverage
- Particle Classification
