The Kirby Morgan® 97 features the 455 Balanced Regulator. The 455 is an all stainless steel regulator with superior breathing performance and the added advantage of compatibility with the SL 27, 17C, KM 37, KM 37SS, KM 57 helmets as well as the KMB 18 & 28 Band Masks. The overall performance of this regulator is outstanding and sets a new performance standard for commercial diving helmets and band masks.

The KM 97 features a quick change communications module, available with either bare wire posts or waterproof connector, and allows for easy, efficient maintenance of the communications. This same communications system is found in all our helmet models (with the exception of the SL 17B and 17C).

The advantages of this stainless steel helmet include the following: Rugged helmet shell and other components No refinishing required if the surface is scratched or gouged Elimination of threaded inserts for securing port retainer to helmet shell.

Note
The minimum operating temperature recommended for this helmet is 37 degrees F, only in regards to regulator performance. Kirby Morgan does offer a hot water shroud kit for the KM 97 (part number 525-761).

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.
