3H

These air horns feature corrosion-resistant cast aluminum housing, stainless steel diaphragms, and a Type 4X enclosure. They are designed for indoor/outdoor use and are activated by compressed air.

The air horns operate within a pressure range of 20 to 150 psi. They are tuned for optimal performance at 80 to 90 psi.

The horns require a 120VAC air valve, which is sold separately. Model EVS-120 is for the 3H, and Model EVL-120 is for the 6H.

The Model 3H has a frequency of 750Hz. It produces 112 decibels at 10 feet and 122 decibels at 1 meter.

The Model 6H has a frequency of 295Hz. It produces 122 decibels at 10 feet and 132 decibels at 1 meter.

The Model 3H consumes 0.20 cubic ft./sec. of air, while the Model 6H consumes 0.45 cubic ft./sec. of air.

The Model 3H is 4.75 in high, 4.75 in wide, and 4.88 in long. It has a 3.0 in diaphragm diameter and a 0.38 in pipe size.

The Model 6H is 9.5 in high, 6.5 in wide, and 12.38 in long. It has a 6.0 in diaphragm diameter and a 0.75 in pipe size.

The Model 3H has a net weight of 1.6 lbs (0.7 kg). The Model 6H has a net weight of 9.7 lbs (4.4 kg).

Models 3H and 6H air horns can be used indoors, outdoors, or anywhere compressed air can be provided.
