For maximum water absorption, solids holding capacity and shutdown protection to assure clean, Dry fuel
The Facet 6" (152 mm) nominal outside diameter FG Series Fuel-Gard monitor cartridges perform three jobs to give you clean, dry fuel. They absorb free and emulsified water, remove ultra-fine solids even when surfactants and fuel additives are present, and shut down system flow when hit with a localized slug of water. They are designed to flow from outside to inside at a rate of 4 gallons (15.14 liters) per inch of length.
Facet FG Series Fuel-Gard monitor cartridges meet the latest edition of Institute of Petroleum (I.P.) Specifications and Qualification Procedures - Aviation Fuel Monitors With Absorbent Type Elements.
The presence of water or solids in the incoming fuel will be indicated by an increase in the pressure differential or a decrease in the flow rate as the cartridge reaches its maximum capacity for solids, water or a combination of both. When either happens, the cartridge should be replaced.
Each FG Series Fuel-Gard monitor cartridge is constructed of various water absorbent media, plus fine filtration layers pleated to give you long life. The perforated metal center tube provides for balanced flow and structural strength. The center tube supports both the pleated section and absorbent media when hit with a localized slug of water. The outer shell retains the media during and after shutdown. The metal end caps provide added strength during shutdown and are epoxy coated to protect against corrosion.
