This is for when your hand pull or real ales are located a fair distance from the serving pump.
This is for 4 products
The CO2 wall mounted primary gas regulator primes each Flo jet gas pump through a secondary regulator
The pump then sucks the beer from the barrel passes it through the pump and then pumps it to each individual hand pull.. normally in a cold water re-circ python
Basically makes it easy to pull long distances without getting arms like Popeye
This can be bought on its own or as part of a full pub cellar beer system
