Facet 21/22SB Series Datasheet

The Facet VF-21SB is a versatile, compact, economical, light weight housing for superior in-line filtration protection. This housing utilizes the same elements as previous 22 Series housings, but offers the benefit of a quick open swing bolt type close along with a new optional mounting bracket for installation.

The Facet VF-21SB Series Fuel-Gard monitors, installed with one Fuel-Gard monitor cartridge, will continually check the entire flow of fuel, not just mere samples, for water or solids contamination. By performing three jobs, this small compact monitor assures clean, dry fuel. It absorbs free and emulsified water, removes ultra-fine solids, and shuts down system flow when hit with a localized slug of water.

Depending on the type of cartridge selected, the housing may be used as a filter, absorptive filter, filter separator or air/gas entrainment separator to remove solids, water, mist or hydrocarbon carryover.

Both interior and exterior surfaces of the carbon steel body are epoxy coated to protect against corrosion. This sturdy, single cartridge housing is easy to maintain and requires only 2 in. (51 mm) base clearance for cartridge change out.

CAUTION: FULL FLOW MONITORS ARE NOT FOR USE IN FUEL CONTAINING ANTI-ICING ADDITIVE (FSII, PRIST, DI-EGME). THIS INCLUDES PRE-MIXED AND MILITARY FUELS CONTAINING THIS ADDITIVE.

Differential Pressure Gauge - The piston-type differential pressure gauge provides a simple visual warning. When 15 psi differential pressure is reached, the gauge indicator moves from green to red zone. This warning will prevent premature cartridge change-out.

Water Sight Glass - The water sight glass provides an easy means to detect water in the sump. The weighted ball, visible in the sight glass, will float only when water is present. The floating ball is an indication water should be drained from the housing to prevent both cartridge contamination and water traveling downstream from the housing.
