HFU Series High Flow PP Pleated Water Filter Cartridge 40″ for RO Pretreatment
Introduction
The HFU Series High Flow Water Filter Cartridge is built for demanding applications where efficiency matters.
With a large 6-inch diameter and coreless, single-open-end design, one HFU cartridge can handle flow rates up to 70 m³/h—dramatically reducing the number of elements and housing size you need . The inside-to-outside flow direction traps contaminants securely inside the cartridge, ensuring cleaner filtrate and safer change-outs . Available in 20″, 40″, and 60″ lengths with ratings from 1 to 100 microns, it delivers reliable performance for RO pre-filtration, power plant condensate, and food & beverage processing

Features
Absolute micron retention ratings from 0.45 to 100 microns
Ergonomically designed handle.
High surface area, high flow rates with low pressure drops
Various configuration in lengths and adaptors
Benefits
Reduce capital expenditure by fewer cartridges and housings used.
Reduce operational expenditure by reduced cartridge change-out frequency, downtime, product waste, labour and disposal costs with longer service life.
Ideal choice for a wide variety of process applications.
Highly durable polypropylene construction, broad chemical compatibility, suitable for rigorous process conditions.
Faster, easier filter change-out.
Direct and economical filter element replacement.
