Band Mask

These are the Band Masks that we will be using for the Surface Supply and the Surface Supply Top-up Course. It is amazing to think that this mask can be used even at great depths in Saturation Diving.

A. 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.
B. Hood/Face Seal provides the diver a comfortable thermal barrier around his head as well as pockets for earphones
C. Steady Flow Valve provides an additional flow of air into the mask for ventilation and defogging.
D. Auxiliary Valve supplies backup breathing gas to the diver.
E. Gas Supply Non-Return Valve prevents loss of gas pressure in the event of umbilical damage, preventing a "squeeze".
F. Communications Connections can be either bare wire posts or a waterproof connector. The waterproof type is recommended when a "round robin" or diver/tender both mics "on" communications system is used.
G. Tri-Valve™ Exhaust Whisker (Patents Pending), which retrofits to many previous Kirby Morgan Helmets and Band Masks®, 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.
H. Water Exhaust automatically keeps water drained from the mask.
I. Demand Regulators The SuperFlow350® KMB 18 and KMB 28 regulator provides easy breathing for hard work.
J. Nose Block Device allows the diver to block the nose to equalize ears.
K. Silicone Oral Nasal Mask is made of a superior silicone material which is hypo-allergenic.
L. Mask Frame hand laid fiberglass for the KMB 18, injection molded plastic for the KMB 28
