HFPP Series String Wound High Flow Filter Cartridges
64mm and 68mm high flow string wound cartridges in 50", 60", 70" lengths, 1 to 10 micron, 80℃, 2.8 bar. Dimensional equivalent to common OEM high flow
What The HFPP Series String Wound High Flow Does In Your Line
HFPP series high flow string wound cartridges are designed for power station condensation water filtration. They feature a high filtration area and high flow rate, with a back washable construction for extended service life. The cartridge is dimensionally equivalent to common OEM high flow housings and fits directly into existing systems without adapters. It uses polypropylene media and core/cage, with EPDM, Buna or Silicone O-rings for fluid compatibility. The 64mm and 68mm outer diameters support 50”, 60”, and 70” lengths, making it suitable for high-volume industrial applications.

Why Buyers Pick This Element
- High filtration area supports high flow rates without increasing pressure drop
- Back washable design reduces replacement frequency and lowers long-term cost
- Polypropylene media and core provide chemical resistance and structural strength
- Dimensional equivalent to common OEM high flow housings for drop-in replacement
- Multiple micron ratings and lengths allow fit to existing system requirements
- EPDM, Buna or Silicone O-rings cover water, solvent and hot service applications
Buyers Who Specify This Cartridge
- Plant engineers in power stations replacing condensate water filters on existing skids
- Procurement teams in steel and chemical plants seeking cost-effective high flow replacements
- Filtration system integrators specifying back washable cartridges for industrial water lines
- Distributors who need dimensional equivalents to quote against OEM part numbers
What It Fixes On The Line
- High flow systems require frequent cartridge changes due to low dirt holding capacity
- OEM high flow cartridges have long lead times and high unit cost per replacement cycle
- Existing housings are full and there is no space to add more vessels for higher flow
- Cartridges degrade quickly under high flow and temperature, leading to premature failure
- Back washing is not possible with standard cartridges, increasing waste and operating cost
Construction Detail
- String wound polypropylene media provides high dirt holding capacity and consistent filtration
- Polypropylene core and cage offer structural integrity under differential pressure
- Back washable construction allows cleaning and reuse, reducing replacement frequency
- Multiple micron ratings available for different filtration purposes and fluid types
- Round double O-ring or threaded adapter options to match installed housing seats
- High flow rate design supports 3.5 to 5 m³/h per 70” cartridge at rated conditions
Materials Of Construction
- Polypropylene string wound media with no adhesives or surfactants
- Polypropylene inner core and outer cage for chemical resistance and strength
- EPDM O-rings for general water and hot water service
- Buna O-rings for hydrocarbon and general industrial water
- Silicone O-rings where low extractables are required

Checks Before It Ships
- Dimensional check of outer diameter, length and adapter against the ordered code
- Media inspection for uniform winding and absence of gaps or loose fibers
- Differential pressure check against the 2.8 bar at 65℃ rating
- O-ring compound and seating verification before packing
What We Can Change For You
- Length selected from 50", 60", or 70" to match the installed housing
- Micron rating selected from 1, 2, 4, 5, or 10 micron for the duty
- O-ring compound chosen from EPDM, Buna or Silicone based on fluid compatibility
- Adapter selected as T = Thread 2-222/fin to match the existing housing seat
- Private label printing and carton marking available for distributors
How It Compares With The Alternatives
| Standard pleated cartridges | HFPP offers higher dirt holding capacity and back washability, but pleated cartridges may offer tighter absolute ratings |
|---|---|
| Melt blown cartridges | HFPP has higher flow and back wash capability, but melt blown may offer better initial efficiency at lower micron ratings |
| OEM high flow cartridges | Same dimensions and fit at a lower landed cost and shorter lead time, without OEM warranty documentation |
| Bag filters | HFPP supports higher flow and back washing, but bags are cheaper for coarse filtration and lower flow duty |
Installing And Running This Cartridge
- Confirm housing bore, seat type and cartridge length before ordering; the adapter code must match
- Start clean differential pressure logging from day one so change-out is data driven
- Use back washing to extend service life; follow recommended cleaning frequency
- Do not exceed 80℃; select Viton O-rings if the duty runs warm or carries solvents
- Flush the housing before fitting a new element so settled solids do not load it immediately
- Lift the element vertically and keep it upright so captured solids stay on the media
