Features:
- 455 Balanced Regulator – Is a downstream balanced poppet design. The 455 Balanced has a multi turn bias adjustment allowing the diver to compensate for variations in supply pressure and changes in physical attitude. The regulator body is made of 316 stainless steel, as are all its other metal components
- Air Train – The air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate.
- Defogging Steady Flow Valve – Provides an additional flow of gas into the helmet for ventilation and defogging.
- Emergency (EGS) Valve – Supplies backup breathing gas to the diver.
- 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 at key points for added durability. It is light and highly impact resistant, and provides a heat/cold barrier as well as being an excellent electrical nonconductor.
- Gas Supply Non-Return Valve – Commercial Rated™, It prevents loss of gas pressure in the event of umbilical damage.
- Nose Block Device – Allows the diver to block the nose to equalize ears.
- Rapid Change Modular Communications Systems – Because the module is easily removed the helmet, repair or replacement of communications parts is quick and trouble free. It is available with either a male waterproof connector or a bare wire post connection.
- Side & Top Weights – Brings unsurpassed balance to the helmet while providing for accessory mounting areas.
- Side Block – Multi use side block has additional ports built in to provide controlled air flow, if needed.
- Silicone Oral Nasal Mask – Made of a superior silicone material which is hypo-allergenic and has a longer work life than latex.
- Whisker Wings – Bubble deflecting Whisker wings keep bubbles further from face port and ears, improving visibility and decreasing internal noise.
- Side and Top Weights – Bring unsurpassed balance to the commercial diving helmet while providing for accessory mounting areas.
- Positive-Lock™ Latch 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 commercial diver’s shoulders, thus helping to prevent any flooding of the commercial diving helmet.
- Head Cushion – Gives the commercial diving helmet a secure, well balanced feel as well as excellent thermal protection during long work periods.
- Quad-Valve Exhaust System – Makes the commercial diving helmet very dry with no loss of breathing performance.
- Internal Adjustable Chin Strap – Along with the adjustable neck pad on the locking collar gives the commercial diver a comfortable, secure fit.
- Adjustable Neck Pad – Is made from a scuff resistant elastomer which is attached to the yoke system. In conjunction with the spring activated front neck dam ring lock, it provides protection for the bottom of the Kirby Morgan Commercial Diving Helmet.

Notes:
The Kirby Morgan Hot Water Shroud (P/N: 25-100), in conjunction with hot water to the commercial diver, should be used whenever commercial diving operations are conducted using HEO2 at water temperatures less than 60°F (15.56°C) for the comfort of the commercial diver. Kirby Morgan DSI further recommends that the hot water shroud be used in conjunction with hot water to the commercial diver whenever commercial diving operations are conducted using air or mixed gas, in waters colder than 36°F (2.22°C) to reduce the possibility of demand regulator icing.
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.
If diving where the water temperature is 36°F (2.22°C) or warmer but the topside air temperature is below freezing, (32°F (0°C) icing of the demand regulator is possible. To help eliminate the possibility of freezing on the surface, warm water should be run over the exterior of the demand regulator prior to water entry, if the hot water system is not used.
Only equipment certified and tested according to EN 250/E DIN 58 642 may be used with the Kirby Morgan 37 commercial diving helmet when conducting commercial diving operations in European EC compliant countries.
The commercial diver’s umbilical assembly should be composed of good quality diving hose that meets industry standards. Generally, gas hose will be married to the communications wire, pneumofathometer hose, and strength member in a manner that will allow the strength member to receive all the strain. There are also good quality umbilicals available that are assembled at the factory using a twisted method which does not require marrying. Regardless of the system used, the commercial diver’s umbilical is the commercial diver’s life line and should always be of excellent quality and maintained carefully.
