FOBs installed in a long draw draft beer system will reduce beer waste and increase beer profits. The use of FOB(s) can increase profits from draft beer sales when installed on a long draw beer dispensing system.

When an FOB is installed on a long draw beer line and the keg empties, the beer flow is stopped immediately. The beer line remains full of beer, instead of filling with
foam.

Keeping the lines full of beer eliminates the need to refill the lines and purge the system with beer when tapping the next keg. This will significantly reduce beer waste. The actual reduction is based on the length of draw of the beer system being considered.

These are best suited to systems used in pubs or breweries, they are not needed in short draw systems like kegerators.
