Multi-Layer PP Filter Cartridge

Multi-Layer PP Filter Cartridge

Multi-layer Cartridges are designed for the wide range of pre filtration application. Particles retention and reduction of bioburden from liquids as well as gases is ensured through coarse (upstream) to fine (downstream) depth filtration. This family of products is particularly suitable for the fluids that contain high bio-burdens or suspended solids. Filters are ideally used for clarification and pre filtration prior to membrane filtration.
The highly retentive, graded porosity design removes particles in sequence by size - larger particles by the more open outer layers and smaller particles by the tighter inner layers. The outer layers act as a pre-filter while the inner layers provide the absolute rating at a specified pore size. This design efficiently spreads the contaminants throughout the media matrix resulting in superior contaminant holding capacity, lifetime and pressure drop as compared to other media cartridges.

Sealing technology Thermal Bonding, No Adhesives, binders or surfactants are used in the manufacturing process. Furthermore, the all-polypropylene construction provides excellent thermal and chemical compatibility with low and high pH chemicals. All filter cartridges are 100% integrity tested to ensure filter performance.
