HFA Series Pleated High Flow Filter Cartridges


HFA Series Pleated High Flow Filter Cartridges are Pall Ultipleat high flow cartridge filters replacement, high quality pleated cartridges manufactured by Hongtek. The outer diameter usually made 6 inch (152mm). High flow filters can be made coreless or inner central core with outer hard cage, single open end when the another end is sealed by O-ring end cap. 

Liquid flow pattern of high flow filter cartridge is from inside to outside. The large diameter geometrical design of polypropylene pleated high flow filter cartridges enlarge surface filtration area, strengthen dirt holding capacity to save the quantities of filter cartridges and improve flow rate when filtration efficiency exceed 99%. High flow pleated cartridges have wide range of chemical compatibility and applications, making them the ideal option for industrial high flow water filtration system to protect RO membrane.

● Gradient pore structure of pleated high flow filters provide layered filter functions

● Outer hard cage can withstand higher pressure than high flow filters made by soft netting

● The reduction of filtration system space could be maximized to 50% so as to lower maintenance costs 

● The highest flow rate of high flow pleated cartridges could get 110 M³/H and Beta 5000 rated (99.98% efficiency)

● Inside to outside filtration pattern of high flow filters ensure holding all impurities stayed inside the pleated media

● High flow pleated cartridges are more economical because of high filtration efficiency and lower waste disposal costs 

● Materials meet FDA requirements with wide chemical compatibility, no resins, binders, or adhesives and 100% integrity testing


● Paints and coatings

● Microelectronic, film and resin

● Water treatment in Power generation

● RO Pre filtration and sea water desalination

● Solvents, API and water filtration in Bio field

● Bottled water, high fructose, edible oil, soft drink and milk
