Foam on Beer Detector (FOB)

Foam on Beer Detectors, or FOBs, are commonly used in commercial draft systems as a way to eliminate product waste and increase profits. When a keg completely empties, and foam passes into the FOB it will shut off flow and in doing so keep the draft line completely full of beer until a new keg is tapped. This means you can hook a fresh keg and continue pouring without foaming issues, preventing you from wasting beer that is otherwise needed to refill the line and purge the system.

The FOB comes with 3/8" Duotight compatible barbs at the inlet and outlet, allowing you to easily hook up EVABarrier tubing with either a 9.5 mm joiner or 9.5 mm to 8 mm reducer. If not using EVABarrier, simply clamp the line directly onto the barb.

Setup and Use:

• Attach beverage line from outlet of keg coupler to straight inlet of FOB.

• Attach beverage line from elbow outlet of FOB to faucet shank.

• Connect fresh keg and push down purge button until the chamber fills with beer.

• Push bottom knob in to lift float then pull out for normal operation.
