Extremely durable plastic
The fully tested and certified BandMask® 28 may be used in mixed gas diving as well as shallow water air diving.
The SuperFlow® adjustable demand regulator provides low inhalation resistance and high gas flow letting the diver breathe easier and work harder. This mask comes standard with the 455 Balanced Regulator. The 455 is an all stainless steel regulator with superior breathing performance.
The Side Block Assembly of both the BandMask® 18 and 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®, coupled with the redesigned hood, not only prevents 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 BandMask® 28 is very similar to the KMB-Band Mask® 18. Many parts of the KMB-Band Mask® 18 are interchangeable with the BandMask® 28. The major difference between the 18 and 28 is the material of the mask frame. The KMB-Band Mask® 18 has a hand laid fiberglass frame (yellow) while the BandMask® 28 frame is an extremely durable injection molded plastic (black). The relative ease of production of the BandMask® 28 frame allows for a lower cost and quicker delivery of this mask. Other differences include: 1) The main exhaust body of the BandMask® 28 is part of the frame itself and uses a #545-041 main 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.
