The K4 series is designed for general signaling services and generate sound by means of vibrating diaphragms that modulate the flow of compressed air into resonating projectors. All horn shapes are mathematically calculated to amplify sound while closely retaining its fundamental frequency and natural harmonics.

These horns can be used for indoor/outdoor applications and are ideal for hazardous location use. Volume is adjustable by regulating air pressure.

Designed for mounting on air supply piping, supplying between 50 and 150 PSIG (3.5 and 10.5 kg/sq cm).

Typical applications include emergency signaling applications in mines, refineries and industrial facilities. Ideal for individual equipment and plant warnings.
