The 455 Balanced regulator, P/N 505-455, sets a milestone in surface supplied breathing performance and is also compatible with all Kirby Morgan Helmets and BandMasks® that feature the SuperFlow® 350 or 450 regulators.
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.
