BLACK KIRBY MORGAN SUPERLITE 27 WITH 455 REGULATOR AND BARE WIRE COMMS POSTS

If the diver is looking for the most compact helmet with the “snuggest” fit, the SL-27 is Kirby Morgan’s smaller unit in our selection of highest quality commercial diving helmets.

The SL-27 comes standard with the Tri-Valve Exhaust System which provides exceptionally dry breathing under all conditions, without increasing breathing resistance. Also setting the SL-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 455 balanced regulator sets a milestone in surface supplied breathing performance. The regulator body is made of 316 stainless steel, as are all its other metallic components.

Features

• 455 Balanced Regulator: The 455 balanced regulator sets a milestone in surface supplied breathing performance. 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 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.
• Head Cushion: Gives the commercial dive helmet a secure, well balanced feel as well as excellent thermal protection during long work periods.
• Port Weight: Provides balance, comfort, and an accessory mounting area.
• Locking Collar Latch System: Consists of two sealed pull pins which are pulled forward to release the neck collar and neck dam locking system. Even when the latches are released, the neck dam maintains a positive seal and will not allow the seal to be broken until the collar actually clears the commercial diver's shoulders, thus preventing any flooding of the commercial diver's helmet.
• Internal Adjustable Chin Strap: Supports, along with the adjustable neck pad on the locking collar gives the commercial diver a comfortable, secure fit.
• Adjustable Neck Pad: Made from a scuff resistant elastomer and, in conjunction with the swing catch, provides protection for the bottom of the commercial diving helmet.
• Neck Dam Swing Catch: Rotates out of the way to allow the neck dam assembly to be unsealed from the commercial diving helmet. This simplifies removal of the commercial diving helmet.
