Kirby Morgan KM 37 Diving Helmet W/ 455 Balanced Regulator

The Kirby Morgan 37 Diving Helmet comes standard with the Quad-Valve™ exhaust system, which has less breathing resistance than the older single valve exhaust while providing an extremely dry hat. This system is recommended for diving in biologically contaminated water. The 455 Is An All Stainless Steel Regulator With Superior Breathing Performance And The Added Advantage Of Compatibility With The SL 27, 17C, KM 37, KM 37SS, KM 57 Helmets As Well As The KMB 18 & 28 Band Masks. The Kirby Morgan 37 is one of the most popular designs in the world. It's considered the standard of the commercial diving industry, as well as the U.S. Navy. Choose the Kirby Morgan 37 if you want a rugged diving helmet with a traditional design.

Features:

455 Balanced Regulator

The 455 Balanced regulator sets a milestone in surface supplied breathing performance and will soon be compatible with all Kirby Morgan Helmets and Band Masks that feature the SuperFlow® 350 regulator. The regulator body is made of 316 stainless steel, as are all its other metallic 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.

Cage Code: The cage code for identifying KMDSI products for U.S. government purposes is 58366.
CR Standards: These helmets meet or exceed all standards established by Dive Lab of Panama City, Florida, and are CR (Commercially Rated) marked.
CE Approved: The KM 37 helmet is CE Approved.
Temperature Limitations: Use at water temperatures below 33 °F (1 °C) requires use of hot water shroud (P/N 525-100) and hot water.
CE Certification: The Kirby Morgan 37 helmet has been tested and conforms to the performance requirements as set forth in Annex II of Directive 89/686/EEC and, as far as applicable, the EN 15333-1:2008/AC:2009 (class B). It is fully CE marked with demand regulator SuperFlow 350 and oral nasals P/N 510-690 and P/N 510-747 (now standard).
Notes: The Hot Water Shroud (Part #525-100) in conjunction with hot water to the diver should be used whenever diving operations are conducted using HEO2 at water temperatures less than 60°F (15.56°C) for the comfort of the diver. KMDSI further recommends that the shroud be used in conjunction with hot water to the diver whenever 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 diver's 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 KM 37 helmet when conducting diving operations in European EC compliant countries.
The 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 umbilical is the diver's life line and should always be of excellent quality and maintained carefully.
