The Model 815 is a high pressure roof mount air horn powered by an on-board air system. Challenger LV produces an ultra-powerful, big rig alerting sound, controlled by a heavy-duty manual lanyard valve.  The horns’ base is painted black enamel and both trumpets have a bright chrome finish, which will dress up any vehicle big or small. Installation is made easy with Wolo’s new flexible inlet hose, with brass fittings, that is hidden from view. Included is a two piece on-board high pressure air system consisting of a 2-1/2 liter steel air storage tank, with a built-in pressure switch and a heavy-duty high-pressure compressor. All moving parts of the compressor are manufactured to Wolo’s strict standards. The compressor motor is carefully balanced and the mounting bracket has rubber bushings, to virtually eliminate all vibration. A 20 foot coiled hose with brass fittings is included to inflate shocks, rafts and other applications, note air system is not designed to inflate applications requiring a large volume such as vehicle tires.  Included in kit is; wire, horn switch, high-pressure hose, flexible inlet hose, lanyard valve, stainless steel mounting hardware, and a rubber gasket for a watertight installation.
