The Fully Tested And Certified KMB® 28 Band Mask® 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 KMB® 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 Band Mask® BandKeepers®
The Tri-Valve® Exhaust System has less breathing resistance than the older single valve exhaust. It retrofits to all previous Kirby Morgan Band Masks®. The Band Mask® 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.
