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 Regulator - This all metal, fully adjustable, Commercial Rated™ demand regulator provides easy breathing and excellent performance with low pressure compressors.
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 lamination. 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 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.
Top Handle - Handle can be removed without breaking seals, making it quick and easy to attach accessories.
Whisker Wings - Bubble deflecting Whisker wings keep bubbles further from face port and ears, improving visibility and decreasing internal noise.

Recommended Lubricants - All helmets and masks are lubricated at the factory with Christo-Lube®. Kirby Morgan recommends Christo-Lube® or Tribolube® for all gas train components. Dow Corning® 111 Silicone or equivalent may be used for helmet and mask components that are used with gas mixtures containing less than 50% oxygen.
Regulator - 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.
Temperature Limitations - Use at water temperatures below 33 °F (1 °C) requires use of hot water shroud (P/N 525-100) and hot water.
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 SL 27® 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.
