High-purity PFA single cartridge filter housings

  • High-purity PFA materials of construction provide the broadest available chemical compatibility and strongest mechanical properties with lowest possible extractables
  • Accepts one 4 in. (10.2 cm) or 10 in. (25.4 cm) 222 O-ring SOE style cartridge
  • 3/4 in. (1.91 cm) NPT and butt weld inlet and outlet connections available
  • Standard 1/4 in. (0.64 cm) NPT upstream and downstream gauge connections
  • Use with fluoropolymer cartridge for an all-fluoropolymer filtration system

Specifications

Maximum Operating Pressure

  • 4.5 bar (65 psig) @ 95 °C (203 °F)
  • 5.2 bar (75 psig) @ 20 °C (68 °F)

NOTE: Maximum operating pressure ratings are vessel ratings only. Safe operating temperature and pressure will depend on the filter cartridge and gasket/O-ring used. For inquiries on compatibility, contact Pall or your local distributor.

  • Head and bowl: High purity PFA
  • O-ring: FEP encapsulated silicone
  • NPT plugs: High purity PFA
  • Threaded head inserts: PTFE coated 316 stainless steel
  • Adapter1: High purity PFA (10 inch model only)

Connections

  • Inlet/outlet: 3/4 in. (1.91 cm) NPT or butt weld
  • Vent & drain: 1/4 in. (0.64 cm) NPT

Cartridge Configuration

  • 10.2 cm (4 in.): M3 (Code 3), 222 O-rings, flat closed end
  • 25.4 cm (10 in.):
    • M8 (Code 8), 222 O-rings, flat closed end

Performance

Housing Differential Pressure vs. Liquid Flow Rate

Unit conversion: 1 bar = 100KPa

Flow rate is for 25.4 cm (10 in.) housing without filter cartridge. For liquids other than water, multiply the pressure drop by the specific gravity of the fluid.

Applications

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.
