High Flow

Radially pleated High Flow cartridge. Ideal for pre RO, Mains water. Single cartridge capable of 80m3/hr meaning smaller systems, less change outs and faster filter changes.

High Flow Capability

The unique construction of CUNOTM High Flow Filters (patent pending) permits flow rates of up to 113 m3/hr (500 gpm) in a single cartridge. The result? Fewer filter elements to accommodate your flow requirements. In fact, the CUNOTM High Flow Filtration System requires as few as one-tenth the number of elements as competitive 2.5” (63,5 mm) pleated cartridges (see Figure 1).

Materials of Manufacture

Filter Media

Each grade of the CUNOTM High Flow Filter is manufactured from melt-blown FDA compliant polypropylene microfibre media, providing high particle removal efficiency with broad chemical compatibility. No adhesives, binders, or silicone are used in the manufacturing process. The raw materials composing these filters are FDA compliant according to CFR Title 21. All support layers and hardware are constructed with polypropylene.


O-rings are available in a variety of materials to suit your applications, including the standard nitrile, Ethylene Propylene Rubber (EPR), silicone, and fluorocarbon.
