BandMask® 28

Call for Price

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^® BandKeepers, 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.

Description

Features:

Air Train
The air train diffuses incoming breathing air/gas onto the face port/lens to defog and ventilate.

Communications
Communications are “non-modular” (like the SuperLite 17B helmet). When ordered with a male waterproof connector (for 4-wire communications), the mask will also include bare wire posts. When ordered with bare wire posts (for 2-wire communications), the port for the MWP connector is plugged.

Defogging Steady Flow Valve
Provides an additional flow of gas into the helmet for ventilation and defogging.

Emergency (EGS) Valve
Supplies backup breathing gas to the diver.

Gas Supply Non-Return Valve
Prevents loss of gas pressure in the event of umbilical damage, preventing a “squeeze”.

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.

Nose Block Device
Allows the diver to block the nose to equalize ears.

Side Block
Multi use side block has additional ports built in to provide controlled air flow, if needed.

Stainless Steel Bands
Bands hold the Hood/Face seal in place on the mask frame. They also provide the mounting studs for the Head Harness (Spider).

The 455 Balanced Regulator
The 455 Balanced regulator sets a milestone in surface supplied breathing performance and is compatible with all Kirby Morgan Helmets and Band Masks that feature the SuperFlow® 350 regulator. The regulator body is made of 316 stainless steel, as are all its other metallic components.

Tri-Valve® Exhaust With Whisker Wings
Retrofits to many previous Kirby Morgan Helmets and BandMasks®, 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.
