Orange-Peel Melt Blown Filter Cartridge

Engineered for demanding filtration environments where standard smooth-surface cartridges fall short, Pullner’s orange-peel cartridge features a textured surface that provides strong mechanical strength and pressure resistance. This combination of durability and high filtration accuracy makes it the go-to choice for filtering high-viscosity fluids and liquids with high solid content — applications where other cartridge types are prone to premature clogging. Part of Pullner’s melt blown filter cartridges range.

Applications

The orange-peel melt blown filter cartridge is designed for applications involving viscous liquids, high solid content, and demanding process conditions:

High Viscosity Liquids: Filtration of viscous fluids and macromolecule polymers
Petroleum & Chemical: Organic solvents, acids, alkalis, oilfield water injection
Food & Beverage: Filtration of alcohol, beverages, and drinking water
Pharmaceutical: Pre-filtration of injections, liquid medicines, and antibiotics
Water Treatment: RO membrane pre-filtration, industrial and municipal water
