    • 455 Balanced Regulator - Is a downstream balanced poppet design. The 455 Balanced Regulator has a multi turn bias adjustment allowing the diver to compensate for variations in supply pressure and changes in physical attitude. The regulator body is made of 316 stainless steel, as are all its other metal components
    • Communications - Communications are “non-modular” (like the SuperLite 17B helmet). When ordered with male waterproof connector (for 4 wire communications), the mask also includes bare wire posts. When ordered with bare wire posts (for 2 wire communications), the port for the mwp connector is plugged.
    • Defogging Steady Flow Valve - Provides an additional flow of gas into the helmet for ventilation and defogging.
    • Emergency (EGS) Valve - Supplies backup breathing gas to the diver.
    • Gas Supply Non-Return Valve - Prevents loss of gas pressure in the event of umbilical damage, preventing a "squeeze".
    • Head Harness (Spider) - Keeps the mask in place on the divers head. The neoprene rubber spider has adjustment holes for varying the tension of the harness.
    • Nose Block Device - Allows the diver to block the nose to equalize ears.
    • Side Block - Multi use side block has additional ports built in to provide controlled air flow, if needed.
    • Silicone Oral Nasal Mask - Made of a superior silicone material which is hypo-allergenic and has a longer work life than latex.
    • Stainless Steel Bands - Bands hold the Hood/Face seal in place on the mask frame. They also provide the mounting studs for the Head Harness (Spider).
    • Tri-Valve® Exhaust With Whisker Wings - Retrofits to many previous Kirby Morgan Helmets and BandMasks®, has less breathing resistance than the older single valve exhaust while providing an extremely dry hat. The Tri-Valve® Exhaust is made of a chemical resistant compound.

    The Side Block Assembly of both the Kirby Morgan BandMask® 18 and Kirby Morgan BandMask® 28 receives the umbilical over the shoulder in the B configuration. They both come standard with the Tri-Valve® exhaust system, and the new BandMask® BandKeepers®

    The Tri-Valve® Exhaust System has less breathing resistance than the older single valve exhaust. It retrofits to all previous Kirby Morgan BandMasks®.The BandMask® BandKeepers® coupled with the redesigned hood not only prevent any separation of the hood from the mask but also makes it impossible for the bands to separate from the mask.

    The communications connections can be either a male waterproof plug in type or bare wire posts.The Kirby Morgan BandMask® 28 is very similar to the Kirby Morgan BandMask 18. Many parts on the Kirby Morgan BandMask® 18 are interchangeable with the Kirby Morgan BandMask® 28. The major difference between the 18 and 28 is the material of the mask frame itself. The Kirby Morgan BandMask® 18 has a hand laid fiberglass frame (yellow) while the Kirby Morgan BandMask 28 frame is an extremely durable injection molded plastic (black). The relative ease of production of the Kirby Morgan BandMask® 28 frame allows for a lower cost and quicker delivery of this mask. Other differences include: 1) The main exhaust body of the Kirby Morgan BandMask® 28 is part of the frame itself and uses a 545-041 Exhaust Cover 2) no comfort insert is required on the "28" 3) the face ports for the 18 and the 28 differ slightly in size.
