The Facet 2" (51 mm.) nominal outside diameter GNG Series Go-No-Go monitor cartridges perform three jobs - they absorb free and emulsified water to less than 2 ppm; 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, giving you clean, dry fuel. The GNG Series Go- No-Go monitor cartridges are designed to flow from the outside to inside at a rate of 1 gallon (3.79 liters) per inch of length.
Go-No-Go monitor cartridges meet the latest edition of Military Specification MIL-M-81380C(AS) for Monitor, Contamination, Aviation Fuel Dispensing Systems.
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 cartridges reach their maximum capacity for solids, water or a combination of both. When either happens, the cartridges should be replaced.
Each GNG Series Go-No-Go monitor cartridge is constructed of various water absorbent media, plus fine filtration layers wrapped around a molded center tube for balanced flow and structural strength - all encased in a protective outer sock material. The end cap material is of injection molded, glass-filled nylon which provides superior strength and ease of maintenance. This material gives excellent support for the o-ring on the mounting/adaptor end.
