The fully tested and certified BandMask® 18 may be used in mixed gas diving as well as shallow water air diving.
The SuperFlow® adjustable demand regulator provide low inhalation resistance and high gas flow letting the diver breathe easier and work harder. This mask comes standard with the large tube SuperFlow® 350 regulator.
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® BandKeepers®, coupled with the redesigned hood, not only prevent any separation of the hood from the mask, but also make 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 BandMask® 18. Many parts on the BandMask® 18B are interchangeable with the BandMask® 28B. The major difference between the 18 and 28 is the material of the mask frame. The BandMask® 18 has a hand laid fiberglass frame (yellow) while the BandMask® 28B 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.
The BandMask® 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 15333-1 (Class C). It is fully CE marked with demand regulator SuperFlow® 350 and oral nasals P/N 510-690 and P/N 510-747 (now standard).
