Foam on Beer

Foam on Beer – FOBs Detectors

Foam on beer detectors, also known as FOBs devices, is a draft component placed in a cooler that detects when a keg of beer is emptied and then goes to work to shut down the beer flow. This eliminates gas and spits of beer from pouring out of your taps. As you re-tap a full keg onto that same line it will also preserve your newly tapped beer from foaming before it pours as it should.  In other words, with a FOB installed on your beer line, you will experience much less foaming when your keg hits empty, and when you tap the new keg, your tap will immediately pour beer. Very little foam waste, no serving downtime for your customers, and none of the extra labor costs involved when an employee spends their time cleaning up the cooler where a blown empty keg has made a mess.

FOBs are also usually a misunderstood draft component in a bar. Generally, newer employees and managers are asked to change the keg without knowing the steps to take in resetting a FOB. The staff must be trained on how they work. Another issue is maintenance. Since the FOB is full of beer, it will get dirty in the same way other equipment will. They turn sticky and are hard to reset, or worse, when the bleed valve (vent) gets dirty enough, it will stick in the open position, and you can bleed a whole keg through it and lose all that product.

We highly recommend FOBs to our customers who have either a Long Draw draft beer system or a Through The Wall draft beer system. They are an inexpensive way to control shrinkage in your bar.

FAQs About FOBs

What is FOB in draft beer systems? FOB stands for Foam on Beer, and is a device used in draft beer systems to prevent the beer from flowing when the keg runs out or when the beer line is compromised. It prevents the wastage of beer and ensures that only quality beer is served.

What are the components of a FOB system? FOB systems typically consist of a FOB device, a FOB sensor, a FOB actuator, and tubing that connects the FOB to the beer lines.

How does a FOB device work? A FOB device works by using a float that rises with the beer level in the line. When the beer level drops due to a keg running out or a compromised beer line, the float lowers and activates the FOB sensor, stopping the flow of beer.

Why is a FOB device important in draft beer systems? A FOB device is important in draft beer systems because it prevents beer from flowing when the keg runs out or when the beer line is compromised, reducing wastage of beer and ensuring that only quality beer is served.

What happens if a FOB device is not used in a draft beer system? If a FOB device is not used in a draft beer system, the beer will continue to flow even when the keg runs out or when the beer line is compromised, resulting in wastage of beer and poor quality beer being served.

How often should a FOB device be cleaned? FOB devices should be cleaned regularly, ideally every time a keg is changed, to prevent the build-up of bacteria and ensure that the device is functioning properly.

Can a FOB device be installed on an existing draft beer system? Yes, a FOB device can be installed on an existing draft beer system by a qualified technician.

What are the benefits of using a FOB device in a draft beer system? The benefits of using a FOB device in a draft beer system include reducing beer wastage, ensuring that only quality beer is served, and improving the overall efficiency of the system.

How does a FOB device affect the pour of beer? A properly functioning FOB device should not affect the pour of beer, as it only stops the flow of beer when the keg runs out or when the beer line is compromised.
