FOB Detector | Stanwell Cellar Buoy Beer & Keg FOB Detector

The Stanwell FOB Detector (Cellar Buoy) is designed to automatically shut off the beer line when a keg empties, preventing gas and excessive foam from travelling through the draught system.

Installing a FOB detector helps keep the beer line full between keg changes, reducing the amount of beer wasted when a new keg is connected and helping staff get back to serving more quickly.

Designed for professional draught beer systems, the Stanwell Cellar Buoy features 3/8" John Guest push-fit connections, an integrated twist bleed valve and a simple float release mechanism for quick resetting after changing a keg.

What Does a FOB Detector Do?

FOB stands for Foam on Beer. A beer FOB detector is installed in the product line between the keg and the dispense point.

When the keg empties, the internal float drops and automatically shuts off the beer line. This prevents gas and foam from travelling further through the dispense system.

Once a new keg has been connected, the FOB can be bled and reset, allowing beer to flow again while keeping the line primed.

This can significantly reduce the beer normally wasted when clearing gas and foam from a long dispense line following a keg change.

Stanwell Cellar Buoy FOB Detector

The Stanwell Cellar Buoy provides a straightforward mechanical solution for detecting an empty keg and shutting off product flow.

Its clear chamber allows the condition of the product to be easily checked, while the integrated controls make bleeding and resetting straightforward during normal cellar operation.

How to Reset the FOB After Changing a Keg

Once the empty keg has been replaced:

1. Connect the new keg to the draught system.
2. Use the integrated twist bleed valve to bleed the FOB chamber.
3. Operate the float release lever to release the internal float.
4. Once the chamber is correctly filled with beer, the line is ready for dispense.

Reduce Beer Waste During Keg Changes

Without a FOB detector, an empty keg can allow gas to enter the product line. This can result in excessive foam at the tap and beer being wasted while the line is cleared following the keg change.

The Stanwell FOB Detector stops the product line when the keg empties, helping keep beer within the line and reducing unnecessary product loss.

For installations with longer beer lines, the potential saving can be particularly useful over repeated keg changes.

Professional FOB Detector for Pubs, Bars & Breweries

The Stanwell Cellar Buoy FOB Detector is suitable for pubs, bars, restaurants, breweries, taprooms, stadiums and other venues using professional draught beer dispense equipment.

It can be incorporated into new installations or added to compatible existing draught systems where improved keg change management and reduced beer waste are required.
