PARTICULATE WATER FILTERS
- 40 to 560 GPM Stainless Steel Housing and "DualSeal" Cartridges

• All Stainless Steel Housing
  Heavy duty 10 ga stainless steel housing rated at 125 psid working pressure.
• Unique “DualSeal” Double O-Ring seal Filter Elements
  Conventional cartridge-type filters depend upon compression of the cartridge top and bottom to effect a seal. However, tests indicate, that the average cartridge loses some rigidity when wet, making it impossible to maintain this original seal.
  
  F Model Filters, however, do not rely on compression. Instead, using an innovative “DualSeal” double O-ring design whereby the cartridge slides over a center standpipe, they are sealed top and bottom by internal O-rings to insure first- day effectiveness for the life of the cartridge.
• PF Cartridges Provide Complete Particle Filtration
  PF elements remove sediment and other suspended particles using cartridges made from thermally-bonded microfibers of polypropylene. "Graded Depth" construction provide element fibers which are wound more tightly toward the core of the cartridge. Consequently, the entire depth of the filter element is used for more effective filtration and longer service life.

F MODEL FILTERS ARE EASY TO SERVICE

No tools needed... remove old cartridges and slide in new cartridges over standpipes in filter housing.

Periodic replacement of the filter cartridge is the only regular maintenance required. Frequency depends on the turbidity of the water supply and the amount of water used. Under average conditions this is once every four months.
