Kahlenberg KM-250-DVM-H marine air horn

The Kahlenberg KM-250-DVM-H is ruggedly constructed using a cast marine aluminium bell, with stainless steel diaphragm and fasteners. It has a thermostatically controlled heated dual solenoids and diaphragm assembly, plus a manual valve assembly. The valve assembly is field adjustable for air pressures between 5-40 bar.

Combined with the patented three-piece hermetically sealed stainless steel diaphragm assembly and self-draining design, the KM-250 keeps on working reliably, between -40°C to 80°C. If you operate in warmer climes then see the Kahlenberg KM-250 model.
