The SuperLite® 27® Gives The Working Diver A Compact, Reliable And Extremely Comfortable Helmet.If the diver is looking for the most compact helmet with the “snuggest” fit, the SuperLite® 27® is Kirby Morgan’s smaller unit in our selection of highest quality commercial diving helmets.The SuperLite® 27® comes standard with the Tri-Valve® Exhaust System which provides exceptionally dry breathing under all conditions, without increasing breathing resistance. Also setting the SuperLite® 27® apart from other helmets is its water dump valve which is mounted on the port side, contributing to the shorter, more compact profile of this helmet.The SuperFlow® 350 regulator featured on the SuperLite® 27® provides outstanding performance. With the diver adjustable system, the regulator can be “tuned” during the dive according to the workload, especially important when using a low pressure compressor with varying supply pressures.

    • SuperFlow® 350 RegulatorThis all metal, fully adjustable, Commercial Rated™ demand regulator provides easy breathing and excellent performance with low pressure compressors.
    • Air TrainThe air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate.
    • Defogging Steady Flow ValveProvides an additional flow of gas into the helmet for ventilation and defogging.
    • Emergency (EGS) ValveSupplies 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 ValveCommercial Rated™, It prevents loss of gas pressure in the event of umbilical damage.
    • Nose Block DeviceAllows the diver to block the nose to equalize ears.
    • Rapid Change Modular Communications SystemsBecause 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 BlockMulti use side block has additional ports built in to provide controlled air flow, if needed.
    • Silicone Oral Nasal MaskMade of a superior silicone material which is hypo-allergenic and has a longer work life than latex.
    • Top HandleHandle can be removed without breaking seals, making it quick and easy to attach accessories.
    • Whisker WingsBubble deflecting Whisker wings keep bubbles further from face port and ears, improving visibility and decreasing internal noise.

    The SuperFlow® 350 regulator on the SuperLite® 27® offers high performance. The regulator has been tested at Dive Lab at Panama City, Florida. It meets 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 exceed all standards established by Dive Lab of Panama City, Florida, and are CR (Commercially Rated) marked.


    The minimum operating temperature recommended for this helmet is 34 °F (1 °C), without the use of the water shroud P/N 525-100 and hot water.

    Without a hot water shroud, the diver may be subject to hypothermia due to cold gas inspiration temperatures.

    NOTE: 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.
