Desco Air Hat

This is a “free-flow” air hat of modern design made of the same materials used in the Navy Mark V and other conventional helmets. Brass castings are deep soldered to a 1/16" spun-copper shell. The window is 3/4" acrylic mounted on the hat with a solid neoprene gasket. The interior liner is adjustable for head size and consists of neoprene fabric applied to foam padding. The hat is remarkable both for its ruggedness and its simplicity of design. It can be completely disassembled and reassembled using only a screwdriver and wrench. It can be easily put on or removed by the diver alone without assistance from a tender.

Using the adjustable exhaust valve, the hat can be adjusted either side of neutral buoyancy under water; and, with its low center of gravity and excellent fore and aft balance, it rests comfortably on the divers head in all working positions. The hat can be used with the neoprene “neck-dam” supplied with each hat or with any diving suit equipped with a cylindrical DESCO “yoke” which then attaches to the hat’s neck-ring insert in lieu of the neck-dam. The neck ring insert mates to the base neck ring of the hat with two independent by complementary gaskets which provide an air and water tight seal.

The hat comes equipped with a “double” one way exhaust valve that incorporates two separate successive seals to prevent possible leakage of water back into the hat through the exhaust outlet. It has a double “air in-take” elbow with two non-return valves for use with a “bail-out” system. The hat is shipped complete with neck ring insert, a size 15 neck-dam and an adjustable jock strap. The hat, unless otherwise specified, comes with a heavy tin plating inside and outside. Standard colors (metallic blue, orange, yellow, red and black) are available at no extra cost. Custom colors are available at additional cost.

The features described above, together with its reasonable cost, make it the hat of choice for divers working at depths where the diver can be supplied with air. When used with a dry suit it provides the diver with maximum protection in contaminated water. Weight of the complete hat is approximately 34 lb.
