Regulator:

The 455 balanced regulator on the SuperLite^® 27^® offers high performance. The regulator has been tested at Dive Lab at Panama City, Florida. It meets all current U.S. Navy and European diving standards.

Cage Code:

The cage code for identifying KMDSI products for U.S. government purposes is 58366.

Note

The minimum operating temperature recommended for this helmet is 34 °F (1 °C), without the use of the water shroud P/N 525-100 and hot water.

Without a hot water shroud, the diver may be subject to hypothermia due to cold gas inspiration temperatures.

NOTE: 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.
