YELLOW KIRBY MORGAN SUPERLITE 17B WITH BARE COMMS POSTS

Many thousands of underwater hours have proved the design to be dependable, comfortable, extremely rugged, and is Commercial Rated. 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 SuperLite 17B also includes the Quad-Valve Exhaust System which has exceptionally low exhalation resistance that you must experience to appreciate. The SL-17A/B Helmet Retainer (chin strap) along with the SL-17A/B Yoke Retainer (yoke strap) make it virtually impossible to have the hat come loose are standard on all new SL-17B helmets.

The Side Block Assembly is standard in the B configuration, receiving the umbilical over the shoulder. 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

• 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.
• 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 Device: Allows the diver to block the nose to equalize ears.
• 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.
• Neck Dam/Yoke Assembly: Secures the commercial diving helmet to the commercial diver’s head and positively prevents accidental removal. The angled neck dam helps the helmet ride comfortably while working face down.
• Low Pressure Plug: Removed and replaced by a suit inflation hose when the commercial diver is wearing a dry suit.
• Communications: bare wire posts or a male Marsh Marine style waterproof connector.
• Latch Catch Mechanism: Locks the neck clamp and yoke in place.
• Water Exhaust: Keeps water drained from the commercial diving helmet.
• Kirby Morgan Quad-Valve Exhaust System: The Kirby Morgan Quad Valve Exhaust System is a superior exhaust system with exceptionally low exhalation resistance that helps to keep the commercial diving helmet free of contaminants in polluted water. The Kirby Morgan Quad-Valve Exhaust System is the first exhaust that isolates the breathing system from the surrounding water with a four valve, low breathing resistance design.
