A standard decompression chamber comes with two compartments, the main chamber and an airlock. The chamber is skid-mounted and has large lifting lugs for increased mobility. The tank will go wherever the diving action is.

Both the inside and outside of the chambers are covered with a special coating. Working pressure is usually 5.5 bar (80psi), but chambers up to 35 bar (515psi) can also be provided. For integration in existing systems, the chambers can be supplied with connection flanges to fit any bell or auxiliary chamber. The skid can be used to integrate the oxygen and air cylinders required to provide a maximum operational independence. The pressure hull has a number of spare penetrators that allow additional systems to be installed. A large size medical lock is a standard feature. View ports with a diameter of 150mm allow observation of both compartments.

The SuperLite® 27® The SuperLite® 27® is the result of years of research and testing. The design gives the working diver a reliable and extremely comfortable helmet.

The SuperFlow® 350 regulator used on the SuperLite® 27® provides outstanding performance. It features a diver-adjustable system so that the regulator can be ‘tuned’ during the dive according to the workload. This adjustment also allows the diver to set the regulator as the supply pressure varies, which is especially important when working with a low-pressure compressor. The diver is also provided with an internally adjustable chin support. This, along with the adjustable neck pad on the locking collar, gives the diver a comfortable, secure, custom fit.

The Kirby Morgan® 37 The Kirby Morgan® 37 is similar to the SuperLite® 27® but has a larger shell. It also includes the Quad-Valve™ Exhaust System.

The Kirby Morgan® 37 diving helmet continues with the manu- facturer’s long tradition of providing the highest quality and superior performance. The Quad-Valve™ exhaust system has less breathing resistance than the older single-valve exhaust and provides an extremely dry hat. This system is recommended for diving in biologically contaminated water. The SuperFlow® 350 regulator is a proven design that provides excellent breathing characteristics over a wide range of depths. The Kirby Morgan® 37 is one of the most popular in the world. A rugged diving helmet with a traditional design, it is considered the standard of the commercial diving industry.

Kirby Morgan® 37SS For divers requiring a metal helmet with the sleek style of the 37, the new stainless-steel Kirby Morgan® 37SS helmet is ideal.

It features a stainless-steel shell, as well as a stainless-steel sideblock, helmet ring, bent tube, handle and other key components. No refinishing is required if the surface gets scratched or gouged. The SuperFlow® 350 is standard on this helmet.

The Kirby Morgan® 37SS features a quick change communications module, available with either bare wire posts or a water- proof connector. This allows for easy, efficient maintenance of the helmet’s communications.
