Shurflo Beer-Ace Beer Gas Pump - FOB Compatible

As opposed to the regular Beer-Ace, this model works with FOBS (empty keg detectors). FOBS detect when the keg is empty and shuts off the supply to the faucet before the beer line drains. Internal keg pressure can be kept low while line pressure can be over 12 PSI. Non-electric. Works off CO2, air, or nitrogen pressure. Handles long line runs and difficult lifts. Warranty: Pump 18 Months.
