HFC Series High Flow Pleated Cartridge Filters are large diameter, single open ended, with outer bandage and with an inside to outside flow pattern. 

High flow cartridge filters have unique crescent-shaped pleat geometry, combined with its large 152.4 mm (6 inch) diameter and high-quality range of available PP or glass fiber filter media. 

Fewer filters and smaller housings for high flow rate applications are allowed due to wide range of chemical compatibility, high dirt holding capacity, high flow rate and good filtration efficiency of high flow pleated filters. In a nutshell, high flow pleated cartridge filters could 100% replace Pall high flow filter cartridges.
