The Kirby Morgan® Diamond Is The Next Modular Variation To The KMDSI Stainless Steel Helmet. When The KM Diamond Is Attached To Our Stainless Steel Helmet Shell The Diver Can Operate In Either A Surface Exhaust Or Ambient Water Exhaust Diving Mode.

Before the diver enters the water, with a simple two-step process, they have the opportunity to switch the helmet into surface vent mode where their exhaled gas is sent to the surface and not into the surrounding water where they are working. On the surface the exhaled gas can be sent to a reclaim system or simply secured on an open deck to vent into the atmosphere. The KM Diamond can be also operated in the open circuit mode for the entire dive.

• 
  Diamond Exhaust Assembly
  Two stage regulator that controls and routs the exhaled gas. Rapid removal and replacement is possible with clear access to all fasteners.
• 
  Air Train
  The air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate.
• 
  Bypass Equalizer Tube
  This system stabilizes the supply regulator, creates a protective bubble layer to the exposed valve and deflects exhaust bubbles from the diver’s field of view when operating in open circuit mode.
• 
  Defogging Steady Flow Valve
  Provides an additional flow of gas into the helmet for ventilation and defogging.
• 
  Emergency (EGS) Valve
  Emergency (EGS) Valve supplies backup breathing gas to the diver. This valve is an integral, built in part of the stainless steel sideblock.
• 
  Gas Supply Non-Return Valve
  Commercial Rated , It prevents loss of gas pressure in the event of umbilical damage.
• 
  Handle
  Removable Grip and handle. Handle can be removed without breaking seals, making it quick and easy to attach accessories.
• 
  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.
• 
  Surface Bypass Valve
  Effortlessly switch from surface vent, (or reclaim), to standard open circuit diving mode. Switching back and forth from diving modes is instant with a single action.
• 
  Stainless Steel Shell
  Each 316 stainless steel shell is precision CNC machined to tight tolerances, to ensure proper fit to all other mating parts. The shell is durable and easy to maintain. Easily cleaned using a Scotch Brite® or similar type cleaning pad.
• 
  Overpressure Relief Valve
  Positive shut off valve is spring loaded. Internal pick up tube reduces chance of exposure and increases effectiveness in dewatering the helmet.
• 
  Water Purge Assembly
  Automatically activates if internal helmet pressure becomes too great. Can also be manually adjusted to improve breathing when operating in the open circuit mode or it can act as a standalone feature to dump exhaled gas directly into the surrounding water.
