Duo-Fine GT Filter Cartridges

Summary

Product identification

DUO-FINE® GT Series Filter Cartridges are high-performance pleated filter cartridges designed to improve lubrication system performance. Key features include:

• Protects critical components from abnormal wear by removing harmful contaminants.
• Extends lubricant life cycles and lowers regular maintenance costs.
• High surface area provides significantly higher contaminant holding capacity than wound or sock type filter cartridges.
• Rigid pleat structure withstands high differential pressures during system start-up.
• Available in standard lengths to retrofit most competitive housings.

Operating limits

• Filter Grade: 3 µm (nominally rated)
• Recommended Change Out Differential Pressure: 35 psid (2.4 bard)
• Maximum Differential Pressure:
  • 100 psid (6.9 bard) @ 68°F (20°C)
  • 50 psid (3.4 bard) @ 150°F (65°C)

Mechanical / hydraulic

• Materials of Construction:
  • Filter Media: Borosilicate Microfiberglass with Acrylic Binder
  • Support Material: Polypropylene
  • Hardware: Polypropylene
• Dimensions (nominal):
  • Outside Diameter: 2 3⁄5" (6.6 cm)
  • Inside Diameter: 13⁄32" (2.78 cm)
  • Lengths: 10" (25.4 cm), 20" (50.8 cm), 27" (68.6 cm), 30" (76.2 cm), 36" (91.4 cm), 40" (102 cm)
• Flow Rate: Flow rate is per 10" (25.4 cm) cartridge. For liquids other than water, multiply differential pressure by fluid viscosity (cP). A graph illustrates typical flow vs. differential pressure for application sizing with UHP Water at 70°F (21°C) for the 3 µm filter grade. See the official PDF for exact tabulated values.

Gaskets/O-rings

Available materials include:

• Buna N (standard)
• Viton A
• Silicone Elastomer
• Nordel

End Configurations

• DOE: Double Open End (with elastomer gasket seals & end caps)
• SOE: Single Open End flat closed end, external 222 O-rings (retrofits other manufacturers’ Code 0)
