This Single Trumpet Mini Air Horn is the loudest single air horn at 126dB. Available with a solid brass or white epoxy powder-coated finish over solid brass. This version is smaller then the regular sized afi trumpet air horn, making it ideal for smaller boats, but stil capable of producing a sound just as loud as the standard sized horn. The diaphragms are made of a non-corrosive Lexan material. The package includes the 12 volt compressor, air tubing, fittings, and hardware. Both models are intended to be mounted on the bow or cabin top of your boat.
