Kirby Morgan Air Control System 5 (KMACS 5) is a lightweight, portable control box for two diver
use in surface supplied air diving operations. The KMACS 5 controls the divers air supply,
communications and monitors the divers depth. It allows two divers clear push-to-talk (two wire) or
round robin (four wire) communications. The KMACS 5 is also available without communications.
The air supply can be either from a low pressure compressor or high-pressure cylinders. The KMACS
5s adjustable first stage regulator reduces the high-pressure air and supplies low pressure through the
umbilical to the divers breathing system. High pressure yokes with DIN adapters permit U.S. standard
scuba cylinders or DIN valve cylinders to be used. A low pressure air supply fitting allows for a L.P.
compressor to be used as the primary air source.
