For Model 730 train horn only. Increase air flow and push the Model 730 Demon™ to unheard of decibel levels. The Ultra BlastMaster™ provides everything you need to add an additional two VX6003 solenoid valves to your Model 730 Demon™. Adding two more solenoids allows each trumpet to have a dedicated air source for dramatically increased flow and a train horn that will push your Demon™ over the edge. Prepare your eardrums; they’re screwed.
