1 7 4 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. Model 3H has a threaded female pipe connection. Model 6H features flanges for additional support. The horn frequency (pitch) depends on both the diameter and length of the projector. Models 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 air valve (sold separately). Use Model EVS with the 3H and Model EVL 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).
