  • Air Train - The air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate.
  • 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 - 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).
  • SuperFlow® 350 Regulator - This all metal, fully adjustable, Commercial Rated™ demand regulator provides easy breathing and excellent performance with low pressure compressors.
  • 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.

Kirby Morgan BandMask® 28 with Posts - P/N: 500-028 Includes:


The fully tested and certified Kirby Morgan BandMask® 28 with Posts may be used in mixed gas diving as well as shallow water diving.

The SuperFlow® adjustable demand regulators provide low inhalation resistance and high gas flow letting the diver breathe easier and work harder with less exertion. Both masks come standard with the large tube Kirby Morgan SuperFlow® 350 Regulator.

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) no comfort insert is required on the "28" 3) the face ports for the 18 and the 28 differ slightly in size.

  • How do you remove the retaining pin from the dial-a-breath adjustment knob?
    Punch out the retaining pin using a 3/32" punch. Use a block of wood with a ¼" hole drilled through it to support the knob. Position the knob so the roll pin is over the hole. The adjustment knob can be held against the wood block allowing the roll pin to be driven into the ¼" hole.
