PFA Fluoropolymer Membrane Filter Cartridges
PFA Fluoropolymer Membrane Filter Cartridges with 500°F max temperature and 60 psi forward pressure. Dimensional equivalent to OEM series.
What The PFA Fluoropolymer Membrane Does In Your Line
PFA Fluoropolymer Membrane Filter Cartridges use expanded PTFE membranes with PFA core, cage, and end caps. All components are fluoropolymer, providing resistance to aggressive chemicals, high temperatures, and strong oxidizing agents. The cartridge operates outside-in and is dimensionally equivalent to common OEM series, allowing direct replacement in existing housings without modification.
Category: Pleated Filter Cartridges · Industries: Pharmaceutical And Life Science Electronics And Semiconductor Food And Beverage Plants
Why Buyers Pick This Element
- All fluoropolymer construction resists strong acids, bases, solvents, and oxidizing gases
- High flow rates with low differential pressure due to hydrophilic PTFE membrane
- PFA encapsulated Viton O-rings maintain seal integrity in aggressive fluids
- No extractables from fluoropolymer materials, suitable for high purity applications
- Dimensional equivalent to installed OEM series, no housing or piping changes needed
Buyers Who Specify This Cartridge
- Chemical plant engineers requiring filtration in highly corrosive environments
- Pharmaceutical and biotech process teams needing low extractable filters
- Semiconductor manufacturers filtering ultra-pure process liquids at high temperature
- Filtration distributors specifying replacements for OEM fluoropolymer cartridges
- System integrators designing systems for aggressive chemical duty
What It Fixes On The Line
- OEM fluoropolymer cartridges have long lead times and high unit cost
- Standard materials degrade in hydrofluoric acid, strong bases, or oxidizing gases
- Filter elements shed particles or fail under high temperature or pressure
- Extractables from elastomers or polymers contaminate high purity streams
- Existing housings cannot accept new cartridges due to mismatched dimensions or seals
Construction Detail
- Expanded PTFE membrane provides high particle removal efficiency and hydrophilic flow
- PFA core, cage, and end caps ensure structural integrity in aggressive fluids
- PFA encapsulated Viton O-rings resist chemical attack and maintain sealing
- Outside-in flow path retains captured solids during change-out
- All components are fluoropolymer, eliminating material compatibility concerns
- Designed to match standard OEM housing dimensions and adapter types
Materials Of Construction
- Expanded PTFE membrane for high particle removal and hydrophilic flow
- PFA support layer, core, cage, and end caps for chemical resistance
- PFA encapsulated Viton O-rings for seal integrity in aggressive fluids
- No adhesives, surfactants, or non-fluoropolymer components used

Checks Before It Ships
- Dimensional check of outer diameter, length, and adapter against ordered code
- Visual inspection of PTFE membrane for defects, gaps, or delamination
- O-ring compound and seating verification before packing
- Seal integrity test at 30 psi reverse pressure to verify no leakage
- Final check of PFA encapsulation on Viton O-rings for full coverage
What We Can Change For You
- Lengths available to match installed housing dimensions (confirm model)
- Micron ratings available based on PTFE membrane specification (confirm duty)
- O-ring compound selected as PFA encapsulated Viton for all configurations
- Adapter type matched to existing housing seat (round double O-ring or claw single O-ring)
- Private label printing and carton marking available for distributors
How It Compares With The Alternatives
| Standard PTFE membrane cartridges | PFA Fluoropolymer series offers higher temperature and pressure resistance, and better chemical stability in aggressive acids and bases |
|---|---|
| Pall PFA series | Dimensional equivalent to Pall PFA series, but with same fluoropolymer construction and no OEM branding |
| CUNO fluoropolymer cartridges | Same materials and performance, but replaces CUNO series without OEM lead time or cost |
| Standard polypropylene pleated cartridges | PFA series resists strong chemicals and high temperatures; polypropylene fails in hydrofluoric acid or oxidizing agents |
Installing And Running This Cartridge
- Confirm housing model, cartridge length, and adapter type before ordering
- Use only outside-in flow; reverse flow may damage the membrane
- Flush the housing before installing a new cartridge to remove settled solids
- Lift the cartridge vertically and keep it upright during change-out to retain captured particles
- Change out at the recommended interval or when differential pressure reaches 60 psi
