Air and Steam Whistles

Kahlenberg Air and Steam Whistles are distinctive, powerful signals backed by decades of successful performance in marine and industrial applications throughout the world.  These whistles are used indoors in factories, for factory warning or directly on machinery, and outdoors in various omni-directional warning installations such as lumber yards, quarries, mines, and similar locations where a reliable, unique sound is required at high volume. Integrated manual air or steam valves are available as well as explosion-proof electric solenoid valves, air strainers and additional accessories.
