The D-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 D-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.

For vessels less than 75 Meters in length
Meets or exceeds IMO Requirements
Low Air Consumption, operates on a wide range of air pressure
Highly reliable, virtually no maintenance required
All brass construction with titanium sounding diaphragm
