The Kahlenberg Model D-0A Air Horn is specifically designed for marine vessels less than 20 Meters in length.  Kahlenberg "Zero Series" horns are nearly identical to the larger Chimetone Air Horns in terms of sound characteristics and finish quality. They are designed to operate with smaller, space saving compressor systems. 

(The D-0A operates with either P449-03 or P449-04 Compressor Kit, V-69-K solenoid valve and M-126 Push Button Switch, each sold separately, see below)

IMPORTANT!!   If purchasing the compressor and valve kit, make sure they are both of the same voltage and match the electrical voltage available on your vessel.
