CUNNINGHAM AIR WHISTLES

Cunningham Whistles are solid bronze castings machined to a fine finish and manufactured in five diaphragm sizes. Each increase in diaphragm size gives lower pitch and greater intensity of sound. The varying lengths within each diaphragm size provide different tones. The shortest horn gives the higher, natural sound while the long horn produces the deeper tone... All whistle models operate over a range of 40 to 140 p.s.i. If necessary, simple adjustments can be made at installation for best tone. The sizes 1 and 2 Whistles, with an optional, thinner diaphragm can be adjusted at the factory to operate on CO2 bottles. (The bottle, available from many marinas, should be equipped with pressure regulator and gauges. A solenoid valve is recommended and can be purchased with the Whistle.
