An air and water hose apparatus for use in an air supply system for firefighters. The air and water hose apparatus has an air hose completely within the water hose. The air and water hose apparatus comprises only a single length of the overall water hose of the system. This ensures that no part of the air hose is exposed to possible damage. The system supplies high pressure air to the firefighters. The system allows for easy connect and disconnect of the air and water hose apparatus to the firefighter's mask and preferably can be used with standard self-contained breathing apparatus having a mask and a regulator. A branched conduit allows several firefighters to be attached to a single air and water hose apparatus.
