SL 17B with red. SF 350 - Kirby Morgan

The fully tested SuperLite® 17B Commercial Diver’s Helmet set the working standard for the commercial diving industry worldwide...

Many thousands of underwater hours have proved the design to be dependable, comfortable, extremely rugged, and is Commercial Rated™ and CE certified. The SL-17B has been tested and certified to meet or exceed all requirements for all governing agencies. It is certified for use in diving operations world wide.

The helmet system consists of two pieces: the neck dam-yoke and the helmet. The diver slips on the angled neck dam with the attached yoke. The neck clamp is then slipped onto the helmet and locked. The locking system not only seals the neck dam to the helmet but also secures the front of the yoke.

The SuperLite® 17B also includes our Quad-Valve™ Exhaust System which retrofits to many of our Helmets. This exhaust has exceptionally low exhalation resistance that you must experience to appreciate. The new SL-17A/B Helmet Retainer™ (chin strap) along with the new SL-17A/B Yoke Retainer™ (yoke strap) make it virtually impossible to have the hat come loose. These upgrades are standard on all new SL-17B helmets and will retrofit to all previous SL-17 A/B Helmets.

The Side Block Assembly is standard in the B configuration, receiving the umbilical over the shoulder (17B as shown). The SuperLite® 17B offers comprehensive head protection, an adjustable demand breathing system for gas economy, antiflooding features, rapid emplacement, a neck dam clamp that mechanically breaks a low-pressure lock, and a trim to fit angled neck dam which seats the helmet comfortably, especially when working in the face down position. The pull pin neck clamp release provides a system for prevention of accidental helmet removal.

Features:

• SuperFlow® Regulator - The 505-027 SuperFlow® "B" regulator on the SuperLite® 17B 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.
• Air Train - The air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate.
• Brass Handle - Handle can be removed without breaking seals, making it quick and easy to attach accessories.
• Chin & Yoke Strap Kit - The SL-17B Helmet ships with a low profile strap system designed to retain the helmet to the neck clamp/yoke assembly in the event these two main components accidentally become separated.
• 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 - Commercially Rated™ It prevents loss of gas pressure in the event of umbilical damage.
• Nose Block - 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. The stainless steel sideblock has a built in EGS.
• 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.

• CR Standards: This helmet meets or exceeds all standards established by Dive Lab of Panama City, Florida, and are CR (Commercially Rated) marked.

Note The minimum operating temperature recommended for this helmet is 34 °F (1 °C), without the use of the water shroud P/N 525-761 and hot water.

Without a hot water and the shroud system, 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.
