The SAT houses a generator, compressor and fill station with multiple air storage vessels in a compact, but efficient design allowing the SAT to be set up anywhere that it can be towed. The SAT can be set up at the scene of an incident and generate its own power from an appropriately sized, stand-alone diesel 3 phase generator to process air and to recharge breathing air bottles. The SAT can be powered by an optional shoreline with transfer switch while at the station.
