Natural Gas Filter Cartridges

Improved Natural Gas Filter/Separator Performance

Velcon Model FO-436G and FO-472G gas filter cartridges have been designed to remove particulate and gross water from natural gas. Both sizes offer:

• Finer Filtration
  
• Gross Water Removal
  
• Proven Performance

The FO-436G and FO-472G have been designed for installations where superior performance features are desired over those offered by standard cartridges.

• High Collapse Strength – In lab tests, the FO-472G averaged > 100 psid collapse strength vs. 34 psid for a leading competitive cartridge.
  
• Improved Filtration Efficiency – Multiple layers of fiberglass in graduated fiber diameters assure maximum efficiency by distributing collected particles evenly throughout the filter body. The fine fiberglass inner wrap assists in gross water removal.
  
• Positive Media Migration Barrier – An inner wrap of cellulose filtration material provides a positive media migration barrier.
  
• Improved Handling Characteristics – An outer wrap of resin coated fiberglass screen retains cartridge shape and density through its useful life, protects against handling damage, and reduces the exterior dirt accumulation typical of fuzzy cotton or dacron stockinette coverings.
  
• Steel End Caps – Aluminized steel provides corrosion resistance while plastisol adhesive assures complete bonding of filter media to end caps.
  
• Buna Gaskets – Seal tightly to mounting stool and top seal plate.
  

Both the 36” FO-436G and the 72” FO-472G cartridges are dimensionally interchangeable with many cartridges in field use. They include:

• Peco Model FG-372
• KingTool Model KTVSWN
  
• Filter Shield Model FS-FG-472-6
• Flo-Line Model Q-FG-372

SPECIFICATIONS Heavy gauge aluminized steel center tube resists corrosion and gives 100 psi collapse strength. Louvered openings provide maximum flow distribution. Resin-impregnated cellulose barrier to stop fibers from migrating downstream. Resin-impregnated fiberglass media, arranged in progressively finer layers, to provide efficient, no channeling depth filtration. 200° maximum operating temperature. Outside-to-inside flow direction. 4-1/2” outside diameter, 3-3/8” inside diameter, 36” and 72” overall lengths.
