PolyNet™ Filter Cartridges

The Next Generation In Depth Filter Technology PolyNet filter cartridges are CUNO'S latest advance in depth filtration technology. The all polypropylene filter is constructed using a patent pending process that utilizes flow enhancing filter media and an innovative flow pattern. The result is an absolute-rated filter with vastly superior on-stream life that provides more cost effective filtration than conventional melt-blown filter technologies.

PolyNet filter cartridges - the new leader in filtration performance!

The PolyNet™ Advantage

• Superior Service Life - as much as 4 times greater dirt holding capacity than competitive filters
• All polypropylene depth filter cartridges for broad chemical and temperature compatibility
• Ratings from 1 - 70 microns to suite a wide range of applications
• Absolute-Rated Performance for consistent filtration quality
• Exhibits superior particle retention under increasing differential pressure

PolyNet Filter Construction

CUNO designed the PolyNet cartridge to provide significantly superior service life while maintaining a consistent filtration efficiency. PolyNet filters achieve this through an innovative cartridge design that allows uniform distribution of fluid flow and contaminant throughout the entire depth of the cartridge. PolyNet filter construction combines a unique polypropylene media with fluid distribution netting to form multiple layers. Critically positioned media flow channels allow greater movement of fluid from layer to layer. Three distinct media sections, made from multiple media/netting layers, are combined to form the filter cartridge.

The outer and middle sections contain multiple layers of interleaved filter media and fluid distribution netting. Within each media layer a portion of the fluid travels through the media while the balance of the fluid is delivered directly to the next distribution layer through the flow channels. The fluid distribution netting provides longitudinal and latitudinal flow paths to evenly distribute fluid flow across the surface of each successive media layer.
