KMB Band Mask 18&28

KMB Band Mask 18&28

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 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 (Patents Pending), and the new patent pending Band Mask® Band Keepers™

The Tri-Valve™ Exhaust System (Patents Pending) has less breathing resistance than the older single valve exhaust. It retrofits to all previous Kirby Morgan Band Masks®.The new patent pending Band Mask® Band Keepers™ 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 KMB 28B BandMask is very similar to the KMB 18. Many parts on the KMB 18B are interchangeable with the KMB 28B. The major difference between the 18 and 28 is the material of the mask frame itself. The KMB 18 has a hand laid fiberglass frame (yellow) while the KMB 28B frame is an extremely durable injection molded plastic (black). The relative ease of production of the KMB 28 frame allows for a lower cost and quicker delivery of this mask.
Other differences include:
1) The main exhaust body of the KMB 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.
