Features:

SuperFlow 350 Regulator

This all metal, fully adjustable, Commercial Rated demand regulator provides easy breathing and excellent performance with low pressure compressors.

Air Train

The air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate.

Auxiliary Port

The auxiliary port will allow for future add-ons and modifications to the stainless steel helmets. It is located on the port side of the shell as shown below.

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.

Silicone Oral Nasal Mask

Made of a superior silicone material which is hypo-allergenic and has a longer work life than latex.

Stainless Steel Shell

After x-ray inspection, 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.

Stainless Steel 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.
Whisker Wings

Bubble deflecting Whisker wings keep bubbles further from face port and ears, improving visibility and decreasing internal noise.

Notes:
The minimum operating temperature recommended for this helmet is 37 degrees F, only in regards to regulator performance. At the time of this writing, no hot water shroud is available for this helmet for heating the diver's breathing gas.
Without a hot water shroud, the diver may be subject to hypothermia due to cold gas inspiration temperatures. Kirby Morgan makes no physiological recommendations regarding minimum safe operating temperatures for divers using this helmet.
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.
Recommended overbottom (OB)gas supply pressure for best performance at depths are calculated by the formula (fsw x 0.445+14.7) + recommended p.s.i. g.
