The Kirby Morgan 47 features the high performance, all stainless steel REX regulator.

The Kirby Morgan 47 consists of two major assemblies: like other “metal bottom” helmets, the helmet shell/helmet ring assembly and the neck dam/neck ring assembly. The chrome plated, machined brass helmet ring houses the latch catches and provides protection for the bottom end of the helmet. An internal, adjustable chin strap, along with the adjustable neck pad on the locking collar, gives the diver a secure, custom fit.

Side & Top Weights: Brings unsurpassed balance to the helmet while providing for accessory mounting areas.

Fiberglass and Carbon Fiber Reinforced Shell: Kirby Morgan has over 50 years experience in composite laminations. The helmet shell is hand laid up glass fiber reinforced thermal setting polyester (fiberglass) with carbon fiber reinforcement for added durability. It is light and highly impact resistant, and provides a heat/cold barrier as well as being an excellent electrical nonconductor.

Defogging Steady Flow Valve: Provides additional flow of gas into the helmet for ventilation and defogging.

Emergency (EGS) Valve: Supplies backup breathing gas to the diver.

Gas Supply Non-Return Valve: Commercially Rated™. Prevents loss of gas pressure in the event of umbilical damage.

Rapid Change Modular Communication System: The module is easily removable. This allows for quick and trouble free repair and replacement. It is available with either a male waterproof connector or a bare wire post connection.

Positive-Lock™ Latch System: This latching system, developed by Kirby Morgan in 1992, consists of two sealed Positive-Lock™ pull pins which are pulled forward to release the neck collar and neck dam locking system. Even when the latches are released, the O-ring sealed neck dam maintains a positive seal and will not allow the seal to be broken until the collar actually clears the diver’s shoulders, thus helping to prevent any flooding of the helmet.

Head Cushion: Gives the helmet a secure, well balanced feel as well as excellent thermal protection during long work periods.

Air Train: Diffuses incoming breathing air/gas onto the face plate to defog the lens.

Silicone Oral Nasal Mask: Made of a superior silicone material which is hypo-allergenic and has a longer work life than latex.

Nose Block Device: Allows the diver to block the nose to equalize ears.

Rex® Demand Valve: (Patents Pending) With its full adjustment balanced piston is a breakthrough design that exceeds all requirements of all government or other testing agencies. It has the best work-of-breathing performance when compared to ANY other commercial diving helmet. This is Kirby’s highest performing regulator, with the lowest breathing resistance and best work of breathing.

Internal Adjustable Chin Strap: The adjustable chin support, along with the adjustable neck pad on the locking collar gives the diver a comfortable, secure fit.

Adjustable Neck Pad: The helmet attached yoke system has an adjustable neck pad which is made from a scuff resistant elastomer. In conjunction with the spring activated front neck dam ring lock, it provides protection for the bottom of the Helmet.

Regulator Performance

Rex® Performance: The Rex® regulator on the Kirby Morgan 47 offers high performance. The regulator has been tested at Dive Lab at Panama City, Florida. It meets or exceeds all current U.S. Navy and European diving standards.

Cage Code: The cage code for identifying KMDSI products for U.S. government purposes is 58366.

CR Standards: These helmets meet or exceeds all standards established by Dive Lab of Panama City, Florida, and are CR (Commercially Rated) marked.

CE Approved: The KM 47 helmet is CE approved.

NOTE
The minimum operating temperature recommended for this helmet is 37° F, only in regards to regulator performance. At the time of this writing, no hot water shroud is available for this helmet for heating the diver’s breathing gas.
Without a hot water shroud, the diver may be subject to hypothermia due to cold gas inspiration temperatures. Kirby Morgan makes no physiological recommendations regarding minimum safe operating temperatures for divers using this helmet.
Usually the greatest danger of demand regulator icing will be encountered on deck when the surrounding air temperature is less than 32°F (0°C). This effect is primarily due to the refrigeration effect of breathing air pressure reduction, and the addition of moisture from the divers exhalation coming in contact with the topside air temperature.
Recommended overbottom (OB) gas supply pressure for best performance at depths are calculated by the formula (FSW x 0.445+14.7) + recommended PSIG.
