The DESCO Air Hat is a “free flow” helmet with a contemporary design, using time proven techniques and materials in its construction, similar to heavy gear helmets of the past. The “free flow” design allows for a constant positive pressure to be maintained in the Air Hat. The standard double exhaust incorporates two separate successive seals to restrict the possibility of leak back.
It conforms to all current regulations of the ADC Consensus Standards, and U.S. Federal Regulations administered by OSHA and the U.S. Coast Guard. The Air Hat has been awarded certification by the European Community for use in EC member countries and carries the CE # stamped on the tail.
Brass castings are deep soldered to a 1/16” thick spun copper shell. The Air Hat is remarkable both for its ruggedness and its simplicity of design. It can be disassembled and reassembled using only a screwdriver and wrench. It can be donned or removed by the diver without assistance from the tender. Using the adjustable exhaust valve the Air Hat can be adjusted to either side of neutral buoyancy underwater with ease. With its low center of gravity and excellent fore and aft balance it rest comfortably on the diver’s head. The interior headliner is adjustable for size and the foam pads are covered in leather for comfort.
The Air Hat is the preferred helmet for working in hazardous environments where contamination is a concern.
