Air Horn System, Complete Scope of Supply, Class 3 Vessel 20-75 Meters, (65-246 Ft.)

Lead Time: As Quoted

A complete marine navigation air horn system that produces a horn signal in excess of 130 dB (1/3 Octave Band), certified to IMO requirements for vessels up to 75 meters in length.

The S-330 Air Horn has been designed to minimize air consumption, and maximize sound pressure output, while retaining the superior finish and durable construction Kahlenberg Air Horns are famous for. The S-330 is much lighter, and significantly smaller than other horns of similar output, yet is certified to IMO Requirements for vessels up to 75 Meters in length, and can be powered by extremely small compressed air systems to minimize associated cost and space requirements on board.
This complete system package for a Class 3 vessel 20 to 75 meters in length includes the S-330 Air Horn with operating valve and air strainer, KB-12 Manual Ship's Bell, M-512 Signal Controller for automated signaling functions, and M-313 "At-Will" Horn Push Button.   See the complete scope of supply technical document attached which is a complete specification including system arrangement (block) diagram and system wiring diagram.
