Chem-Fine Melt Blown Halar Filter Cartridges

Summary

Product identification

The Chem-Fine™ Melt Blown Halar Series Filter Cartridges offer increased chemical and thermal resistance, great durability, and mechanical strength. They utilize extremely pure filtration media and are free of resins, binders, and adhesives. The media is highly resistant to ozone.

Key features:

• Halar media offers increased chemical and thermal resistance
• Great durability and mechanical strength
• Extremely pure filtration media
• High effective surface area per 10" (25.4 cm) cartridge
• Very low initial pressure drop
• Free of resins, binders, and adhesives
• Media very resistant to ozone

Performance Specifications

• Filter Grades: 5, 10 µm
• Liquid Retention Ratings:
  • CFT 5: 90% Efficiency at 5 µm, >99.9% Efficiency at 10 µm
  • CFT 10: 90% Efficiency at 10 µm, >99.9% Efficiency at 15 µm
  • Note: Liquid removal ratings are based on Pall’s Dynamic Efficiency test protocol.

Operating limits

• Maximum Forward Differential Pressure:
  • 70 psid (4.8 bard) @ 120°F (49°C)
  • 50 psid (3.4 bard) @ 180°F (82°C)
• Recommended Change-out Differential Pressure: 35 psid (2.4 bard)

Mechanical / Hydraulic

Flow vs. Differential Pressure: The data sheet includes a graph illustrating typical flow rates versus differential pressure for application sizing (for 5 µm and 10 µm cartridges, per 10" (25.4 cm) cartridge, using water at 68°F (20°C)). See the official PDF for exact tabulated values.

Toxicity and Rinse-Up

• Toxicity: All polypropylene components meet specifications for biological safety as per USP Class VI-121°C plastics (gaskets/O-rings excluded).
• Rinse-Up: Rinse-up to 18 Megohm-cm with minimum throughput.

Applications

• Electroless nickel plating solutions
• High purity chemical filtration
• Ultrapure water systems using ozone
• Hot ultrapure water systems

Ordering Information

Products are ordered using a code sequence that specifies:

• Filter Grades (e.g., 5 µm, 10 µm)
• Cartridge Lengths (e.g., 4", 10", 20", 30", 40")
• End Configurations (e.g., DOE with gasket seals & end caps, SOE flat closed end with various O-ring styles)
• Support Material (Polyester upstream/Halar downstream, or Halar upstream & downstream)
• Hardware (Polyester, Polypropylene)
• Gasket/O-ring Materials (e.g., Silicone, Nitrile, Fluorocarbon Elastomer, FEP Encapsulated Silicone) See the official PDF for detailed part number codes and options.
