Designed for use with HornBlasters train horns, this 200 PSI air system delivers unparalleled performance. It can refill itself in just 1 minute 11 seconds, and sports two large 1/2" NPT ports to make sure your horns get all the air they need! This 12 volt extreme series compressor delivers best in class performance and comes with an abundance of features: an oil-less design, heatsink with cooling fan, integrated air filter, vibration isolaters, and is completely moisture and dust resistant. Other basic features include a high performance PTFE piston ring, stainless steel valves, and thermal overload protection. The compressor weighs 15.5 lbs and measures 12.5" in length, 5.5" in width, and 8.0" in height. The compressor draws just 35 amps running at its peak performance. This 2 gallon tank is insanely strong, built from american steel. It's been internally coated to resist rust and has a matte black powder coating on the outside. It features 4x 1/4" ports, and 2x large 1/2" ports: we designed it this way to reduce the number of reducers you would have to use. While having two 1/2" ports for accessories that need high-flow, the 1/4" ports fit the compressor, safety-valve, pressure switch, and compressor all without any adapters! This means less chance of leaks, and easier installation.
