FOAM DETECTORS (FOBS)

The FOB (Foam On Beer Detector) is an essential accessory for any long‑draw draft system. It instantly stops the beer flow when a keg is empty, preventing the lines from filling with foam or gas.

Result: less waste, higher profitability and uninterrupted, consistent service.

How it works:

When a keg is full, the beer pushes an internal float upward, allowing the flow. When the keg is empty, the float drops and automatically shuts off the flow. Once a new keg is connected, simply purge the gas through the valve to restart the system.

Advantages:

• - Reduced losses: prevents wasting several litres of foam at each keg change.
• - Time‑saving: no need to manually re‑prime the lines.
• - Improved service quality: every glass is served with fresh, non‑foamy beer.
• - Easy installation: fits between the keg and the beer line, compatible with long‑draw systems.
