Kahlenberg S-330

The Kahlenberg S-330 marine air horn provides a fully IMO compliant and ABS certified sound signal for leisure boats and commercial vessels up to 75m (246ft) but in a very compact and efficient package. With a choice of finishes for commercial and superyacht use

The size and efficiency of the Kahlenberg S-330 is a result of detailed design effort on its special alloy diaphragm that produces the requisite levels of sound for very modest air consumption. The horn has been extensively tested and refined in Kahlenberg’s own anechoic test chamber.

The performance of the horn has subsequently been approved by ABS.

As a result of this design effort the S-330 outperforms competitors in terms of its air consumption and form factor. This also leads to corresponding benefits below decks as extremely small DC or AC compressor systems and tanks can be utilised while providing ample capacity to IMO requirements for all required signals.

This makes the S-330 an extremely attractive proposition for vessels where weight and space saving is a consideration or where a compact IMO compliant back-up whistle to the vessel’s main sound signal is required.

As with all Kahlenberg sound signals the S-330 is built in quality materials – spun brass and cast bronze, with a special alloy diaphragm. It can be supplied in sky white powdercoat or chrome. It is constructed with aesthetics in mind to match the best superyacht finishes, with no ugly seams in the bell.

Because of the choice of design and materials you can expect extremely long and reliable service.
