Z-320-SC Self-Contained Air Horn

Z-320-SC Self-Contained Air Horn

Finish

The Kahlenberg Model Z-320-SC Self Contained Air Horn represents a new concept in sound signaling for vessels over 75 meters in length. Using an internal, direct drive air source, this new horn is pneumatic in nature but requires no external compressed air supply. Only one low amperage A.C. single phase or three phase electrical connection is required for power. Completely contained in a thermostatically controlled, heated, IP-56 enclosure, the Z-320-SC offers a new standard for reliability and longevity in harsh marine environments, previously matched only by an air horn that requires an external air source. The Z-320-SC requires a special motor controller (sold separately), Kahlenberg Model M-66 or M-67, for use with 50 Hz A.C. power applications. For dual whistle applications on vessels 75-200 meters, pair with KM-250-DVM-H Air Horn.

  • Type approved for vessels 75-200 meters in length
