Kahlenberg KM-165 marine air horn

The Kahlenberg KM-165 is ruggedly constructed using a cast marine aluminium bell, with stainless steel diaphragm and fasteners.

A patented three-piece hermetically sealed stainless steel diaphragm assembly and self-draining design ensure that the KM-165 keeps on working reliably, between -4°C to 80°C. If you operate in cold water climes then see the Kahlenberg KM-165-DVM-H model.

Can be used with the Kahlenberg KM-135 air horn or KPH-130C piston horn for dual whistle systems on vessels over 200 metres.
