PTFE Membrane Cartridge With PFA Hardware


The all-fluoropolymer filter cartridge series is ideal for aggressive wet etch and clean applications.
The PTFE membrane offers high flow rates at low pressure drops, while the PFA440HP hardware delivers wide chemical compatibility and high temperature resistance.
 


Feature
Excellent chemical compatibility. 
  • Suitable for filtering organic solvents and acid bases. 
  • Pleated design for increased surface area.
  • Low pressure loss and longer service life.
  • Retention rating down to 0.05 μm.
  • Graded pore density for higher dirt holding capacity.
  • Rigid polypropylene outer cage protects filter media.
  • Manufactured from materials which are listed for food contact applications in Title 21 of the U.S. Code of Federal Regulations. 
  • Cartridges are free of binders, resins, and adhesives.
  • Cartridges are available with wet-pack option (60/40 IPA/DI water solution) to eliminate the need to wet-out in the environment.
