Applications

  • Acid etch systems - including Piranha Etch Solvent Strip applications
  • Most aggressive and/or high temperature acids or solvents

Recirculating Applications

Retention ratings, by convention, are for single pass applications. Many applications involve recirculating systems, where the filter media has several opportunities to capture contaminant. For example, in a 15.1 liter (4 gallon) system circulating at 7.6 lpm (2 gpm), the fluid passes through the filter cartridge five times in ten minutes. Thus, the effective retention of a filter cartridge is much finer. Specifically, a cartridge rated at 0.5 μm (nominal) on a single pass is often an effective 0.2 μm (nominal) filter on a recirculating basis.

Additional High Temperature Materials

Pall can also supply DFT Classic filter cartridges in polyphenylene sulfide (PPS) for high temperature and aggressive applications. Additional PTFE products are also available, including the Fluoryte™ Series filter cartridge, an all-fluoropolymer membrane cartridge. Contact your local Pall representative or distributor for specific information on these products.

2 Because so many factors (e.g. elevated temperatures) can affect the
chemical resistance of a given product, you should pre-test under your
own operating conditions observing applicable safety practices such as
those given in the Material Safety Data Sheet for each chemical. Pall
Corporation can provide specific compatibility guidance, testing and data
upon request.

Typical Flow vs. Differential Pressure for Application Sizing



Unit conversion: 1 bar = 100 kPa

Flow rate is for a 25.4 cm (10 in) cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP).
