Professional diving helmet DESCO

for weldinghyperbaric

The DESCO Air Hat was designed in 1968, and has continually evolved to meet the requirements of the commercial diving industry. Major upgrades to the design of the Air Hat over the years were made so they could be retrofitted to older helmets thus increasing their service life. The design of the Air Hat maximizes safety, durability, and reliability, while requiring simple routine maintenance and care. The DESCO Air Hat 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 DESCO Air Hat is a "free flow" helmet of contemporary design, using time proven techniques and materials in its construction, similar to the heavy gear helmets of the past. 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 easily 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 divers head. The interior headliner is adjustable for size and the foam pads are covered in leather for comfort. The DESCO Air Hat is the preferred helmet for working in hazardous environments where contamination of the diver is a concern. The "free flow" or "overpressure" design allows for a constant positive pressure to be maintained in the Air Hat.
