Features

Models 3H and 6H air horns offer the industrial market a variety of tones and sizes to meet a wide-range of needs.  Our air horns feature corrosion-resistant cast aluminum alloy housing and include long-lasting stainless steel diaphragms.

These precisely machined horns will yield peak performance at proper working air pressures and are virtually indestructible. The 3-inch horn (Model 3H) has a threaded female pipe connection. The Model 6H features flanges for additional support. The horn frequency (pitch) depends on both the diameter and length of the projector.

The 3H and 6H air horns can be used indoors, outdoors, or anywhere compressed air can be provided. They also are the loudest audible signals offered for indoor applications. The horns require a 120VAC Federal Signal air valve (sold separately). Use Model EVS-120 with the 3H and Model EVL-120 with the 6H. They are not subject to sparking and are ideal for hazardous locations (valves need to be located in a non-hazardous location).
