Kellerboje/Anhänger-Detektor 3/8" 9,5mm

FOB Detector for Beer Line Systems | Cellar Bouy by Stanwell

Keep your beer lines primed and reduce waste with the Cellar Bouy FOB Detector by Stanwell – an essential tool for any draught beer system.

FOB (Foam On Beer) Detectors are installed on pressurised beer lines close to the keg and after any Flojet pump (if used). Designed to detect when a keg runs empty or when excess gas enters the line, the FOB automatically shuts off the flow by dropping its float, sealing the outlet. This prevents foam and keeps the beer line full, reducing downtime and product waste when changing kegs.

Once a fresh keg is connected, the system can be reset by:

• Using the twist-bleed valve to release trapped gas and refill the chamber.

• Turning the float release lever to reopen the line.

• Resetting the lever back to its starting position.

Key Features:

• 3/8” John Guest Push-Fit Inlet & Outlet (Product Connections)

• 3/16” John Guest Outlet for Bleed

• Wall/Panel Mounting Bracket Included

• Integrated Twist-Lever Bleed Valve

• Easy Float Release & Reset Lever

Ideal for pubs, bars, breweries, and mobile bar setups looking for consistent beer quality and efficient cellar management.
