Federal Signal 3H 4H 4M 6H Air Horns are the loudest audible signals offered for indoor applications. 

Air-horns can be used indoors, outdoors, or anywhere compressed air can be provided. 

Federal Signal offers a line of air horns in a variety of tones and sizes for the industrial marketplace. High, medium and low tones are available which provides a wide range of frequencies and high sound output. Federal Signal air horns feature a one–piece, cast aluminum alloy housing which has been treated to provide corrosion resistance. The horns include specialized long–lasting stainless steel diaphragms. These precisely machined horns will yield peak performance at proper working air pressures and are virtually indestructible. The 3– and 4–inch horns (Models 3H, 4H, 4M) have threaded female pipe connections. The Model 6H features flanges for additional support.

The 3– and 4–inch horns (Models 3H, 4H, 4M) have threaded female pipe connections. The Model 6H features flanges for additional support.

Federal Signal air horns operate with 20 to 150 p.s.i., (pounds per square inch) but they are tuned for 80 to 90 p.s.i. operation. The horn frequency (pitch) depends on both the diameter and length of the projector. Decibel output at 10 feet is 122dBa (132dBa @ 1m).

The horns require a 120VAC Federal Signal air valve. Use Model EVS with the 3H, Model EVM with the 4M and Model EVL with the 6H.

Airhorns can be used indoors, outdoors, or anywhere compressed air can be provided.

They are not subject to sparking and are ideal for hazardous locations (the valves need to be located in a non–hazardous location).
