Model FGS Fuel-Gard® Spin-On Filters


Model FGS

Facet’s aviation spin-on filters are designed to meet EI 1583 effluent requirements and 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.

The filters are designed to flow at a rate of 13 gpm (FGS-O-405) and 15 gpm (FGS-O-409).

Features & Benefits
  • Removes free and emulsified water
  • Removes ultra-fine solids
  • Designed to shut down system flow under slug conditions
