Flotrex PN

Summary

Product identification

The Flotrex PN (FPN) series are pleated filters featuring polypropylene microfiber media. They offer an economical filtration solution designed to protect final filters, providing superior chemical compatibility due to their all-polypropylene construction. These filters utilize gradient density, thermally bonded polypropylene media, which contributes to excellent dirt-holding capacities and reliable retention characteristics. FPN filters are free of adhesives or additives, as the sleeve and end caps are thermally bonded.

They are available in the following nominal pore size micron ratings: 0.2, 0.45, 1, 2, 3, 5, 10, and 30 µm.

Typical applications include:

• Filtration of liquid polymers, coatings, and inks
• Filtration of bulk chemicals
• Beer trap filtration
• Post Carbon bed and DI bed filtration
• Pre-filtration to protect expensive final filters

Materials of Construction

• Filtration Media: Polypropylene Microfiber
• Support Layers: Polypropylene Microfiber
• Core and Cage: Polypropylene
• Endcaps and Adapters: Polypropylene

Mechanical / hydraulic

• Dimensions:

  • Nominal O.D.: 2.75” (70 mm)
  • Nominal I.D.: 1.25” (31 mm)
  • Effective Filtration Area: Varies by model (e.g., 4.8 ft² (0.45 m²) for FPN92 to 7.3 ft² (0.68 m²) for FPN10, FPN30). See the official PDF for exact tabulated values per model.

• Operating limits:

  • Maximum Forward Differential Pressure: 60 psi (4.1 bar) at 70ºF (21ºC)
  • Maximum Reverse Differential Pressure: 30 psi (2.1 bar) at 70ºF (21ºC)
  • Maximum Operating Temperature: 180ºF (82ºC) at 10 psid (0.69 bar) in water

Operational Notes

• Flotrex PN filters can be autoclaved or in situ steam sterilized (up to 257°F [125°C], 30-minute cycles) for a maximum accumulated exposure of 10 hours. Alternatively, they may be sanitized with compatible chemical agents.
• Veolia certifies that the materials meet U.S. FDA requirements for food contact under applicable regulations in 21 CFR.
• These filters meet the test criteria for USP Class VI-121°C Plastics.
• Aqueous extracts from Flotrex PN filters contain less than 0.25 EU/ml and typically exhibit low levels of non-volatile residues.
• Chemical compatibility should be verified for specific applications.

Flow Performance

Table 4, which provides flow performance in clean water, is referenced but its content is not included in this extract. Data is based on 10” length filter. See the official PDF for exact tabulated values.

Ordering Information

Ordering options allow for selection of:

• Nominal Micron Rating (0.2 µm to 30 µm)
• Nominal Cartridge Length (10, 20, 30, or 40 inches)
• End #1 Adapter type (e.g., Open End Gasket, various O-rings, O-rings with Stainless Steel Insert)
• End #2 Adapter type (e.g., Open End Gasket, O-rings, Closed End Cap, Fin Adapter)
• Elastomer Material (e.g., Buna-N, EPDM, Silicone, Teflon, Viton)

See the official PDF for detailed ordering codes and combinations.
