  • (1) Logbook with Pen - P/N: 120-001
  • (1) Helmet/Mask Bag - P/N: 500-901

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.

Description

The Kirby Morgan KM 97 Dive Helmet with Posts is the newest of all Kirby Morgan dive helmets. The All-New 455 Balanced Regulator sets the KM 97 apart from all other models. The 455 balanced regulator is all stainless steel and offers virtually the same superior breathing performance as the REX® regulator, with a lower profile. The overall outstanding performance of the 455 regulator sets a new standard for commercial diving helmets and BandMasks®.

The Kirby Morgan® 97 helmet has been tested and conforms to the performance requirements as set forth in Annex II of Directive 89/686/EEC and, as far as applicable, the EN 250:2000, EN 250/A1:2006 and EN 15333-1:2008 (class B). It is fully CE marked with balanced 455 demand regulator and oral nasal mask P/N 510-747.

The KM 97 has all the advancements & features found in our other stainless steel models: rugged helmet shell that is easy to maintain - no refinishing required if the surface is scratched or gouged, elimination of threaded inserts for securing the port retainer to the helmet shell, elimination of shell mounted weights, removable grip and handle (handle can be removed without breaking seals, making it quick and easy to attach accessories), and a “built in” emergency valve that is an integral part of the stainless steel sideblock.

The Quad Valve Exhaust System and quick change modular communications are also standard on the KM 97. These and many other KM 97 parts are shared with other models. If you keep a Kirby Morgan® helmet spare parts inventory, you’re already stocked with many KM 97 spares.

Ask a Question

  • Why is my Stainless Steel Helmet Rusting?

    Kirby Morgan would like to assure all stainless steel helmet owners, that the helmet shells are not actually rusting. All of these helmet shells and other main components, are cast and machined from a highly corrosion resistant grade of 316L stainless steel. The investment casting process can produce a very good finish, but this still requires more processing to be acceptable. Each helmet shell is initially hand finished, then, it is processed to a very smooth surface using specialized friction finishing equipment. Even after all this processing, these smooth surfaces will still have small surface porosity that can trap foreign matter, some of which can “rust”. This is what will make the surfaces appear to be rusting. This foreign matter that may be trapped, needs to be cleaned away, and the surfaces need to be protected. Basic cleaning and protection should be performed on a regular basis and may need to be performed more often depending on what type of environment the helmets are used in. 

     NOTE, This “Rusting” issue can also be seen on Fiberglass helmet shells and chrome plated brass parts. It is what is stuck to those surfaces that is “rusting”. Not the fiberglass or chrome.

     Cleaning Procedures for the stainless steel helmet

    Thoroughly clean the components with a cleaning soap such as Simple Green. A soft scrubbing tool can help to remove excess materials. Dry the components and wipe completely with Isopropyl alcohol and allow to evaporate. Using a kitchen sponge with an abrasive side. Wet and apply hand soap that contains a slight abrasive (LAVA hand soap works very well, or Go-Jo Pumice, citric hand soap), and simply rub onto the affected area of the helmet shell. The unwanted stains will easily be removed.

     NEVER USE STEEL WOOL TO PERFORM THIS TASK. It will deeply imbed iron particles into the stainless and may cause severe rusting to the component.

    Citric acid or diluted vinegar can be used to passivate stainless steel and remove any light rust. A lemon half works well as a scrubbing tool, and at the same time provides the citric acid to help eliminate small surface particles of rust. Allow enough liquid to deposit on all affected surfaces and allow it to settle for at least 30 minutes. Rinse and re-apply as needed. Rinse again and finish wipe with the Isopropyl alcohol allow to dry completely.

    Apply at least 2 coats of a good quality paste wax. This will help seal surface porosity to prevent foreign matter from being trapped, which may then rust.

    It is best to clean as much of the helmet surfaces as possible, rather than cleaning only affected areas, as this will help prevent any future issues. A basic cleaning and waxing procedure should be performed as part of a routine cleaning regiment.

    Kirby Morgan suggests the use of lemon juice/lemons, or vinegar for the source of acid. These types of acid will help dissolve certain stains, rust and certain residue buildup such as hard water and mineral deposits. Because they are natural and non-toxic, Kirby Morgan highly recommends them for this procedure.

     NOTE: All new stainless helmet shells are electro chemical cleaned (electropolished) and friction polished to a very smooth exterior surface finish. If so desired, the surface can be brought to a higher luster using basic polishing techniques, (i.e. polishing compounds and light buffing techniques).
