The Kahlenberg D-330 twin trumpet air horn provides remarkable IMO certified performance for vessels up to 75m (246ft) in length, in a lightweight and compact package.

This size also means that it requires a very modest air supply, making minimal demand on onboard systems or requiring a very small standalone compressor set.

The Kahlenberg D-330 marine air horn is robustly engineered in cast bronze and spun brass. It can be supplied in a variety of finishes including Kahlenberg’s durable chrome plate, or TGIC sky white powder coat.
