By enclosing the diver’s eyes, nose and mouth, the EXO permits nearly normal speech when used in conjunction with most wireless, and all hardwire underwater communication systems. Its light weight design allows divers to work long dives without jaw or neck fatigue. This mask has a modular communications design that permits rapid and simple maintenance. An optional Hard Shell gives added surfaces for mounting lights, cameras etc. The ear equalization device, a nose block which is adjustable to several different heights, fits a wide variety of noses and faces. The oral nasal helps keep the CO2 levels to a minimum and improves breathing and communications.
The BALANCED REGULATOR EXO-BR was developed to meet strict new European CE requirements.and is fully CE approved as well as U.S. Navy approved. It meets and surpasses EN 250 requirements for regulator performance. The EXO-BR frame is the same safety yellow as the standard SuperLite Helmets and KMB 18 Bandmasks.
The EXO-BR Balanced Regulator helps reduce the work of breathing for the diver. The regulator balances the intermediate air pressure against the valve sealing pressure inside the regulator. This enables the regulator to instantly adjust to changes in line pressure. The Balanced Regulator provides improved breathing and is adjustable for a wide range of intermediate pressures between 100 PSI – 230 PSI.
EXO Skeleton Frame: A strong injection molded plastic external frame gives the head harness an even pull completely around the mask seal. The EXOskeleton does not touch the diver’s face. It is suspended just slightly off the face to hold the communication and breathing equipment in place without discomfort.
Head Harness: A pull through fixed buckle type with an automatic locking feature. Quick release buckles are featured on each rugged, double wide strap.
Communications Module: The EXO-BR is available in 3 different modular communication configurations: No communications (blank module), Bare wire post communications, or the most popular; 4 pin mail waterproof connector when a 4 wire “round robin” system is desired (see Accessories tab, DSI 315-215). Compatible wireless systems are available through several different manufacturers.
EXO-BR Balanced Regulator: CE approved as well as U.S. Navy approved. It meets and surpasses EN 250 requirements for regulator performance.
Regulator Adjustment: Provides demand regulator adjustment for a wide range of incoming air pressure. In addition, it can serve as a steady flow valve. Some divers prefer a slight steady flow on surface supplied air when air consumption is not a factor.
Silicone Oral Nasal Mask: Made of a superior silicone material which is hypo-allergenic and has a longer work life than latex.
Mask Seal: Comprises the main rubber body of the mask. It is a soft neoprene that seals comfortably on the diver’s face. The EXOskeleton is used to hold this soft rubber seal in place on the diver’s face for a solid seal.
Faceplate Lens: Tempered glass for strength and minimum fogging. A strong plastic frame surrounds the glass to seal on the rubber mask seal.

Operational Specifications & Limitations
The CE approved EXO-BR complies with EN 250 (edition May 1993). The EXO-BR has been CE tested for scuba use with the KMDSI SuperFlow first stage regulator. The EXO-BR has also been CE tested for surface supplied umbilical diving. Regardless of the mode being employed, all components used with, or in conjunction with the EXO-BR must be CE approved.
Air Supply Pressure
All Kirby Morgan masks and helmets are designed for a maximum working supply pressure of 225 psig (15.5 bar). What this actually means is the gas train components i.e., intermediate supply hose, demand regulator and manifold assemblies are designed to operate at gas supply pressures of up to 225 psig (15.5 bar) above the surrounding ambient pressure.
The regulator adjustment knob is capable of holding back this pressure, with a little bias in reserve. This is so the professional working diver can adapt the helmet or mask to various types of supply systems found on dive stations throughout the world. It is not the intention that the mask or the helmet be normally operated at the high end pressure 225 psig. The normal maximum supply pressure to the EXO-26 BR should be dictated by the depth and selected in accordance with the specification lists for the mode of diving being employed.
