Kirby Morgan Air Control System 5 (KMACS 5) is a lightweight, portable control box for use in surface supplied air diving operations.
The KMACS 5 controls the diver’s air supply, communications and monitors the diver’s 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 5’s adjustable first stage regulator reduces the high-pressure air and supplies low pressure through the umbilical to the diver’s 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.
A complete pneumo system with dual reading gauges (both US Standard and Metric) is provided for each diver, as well as a shut-off/bleed system that uses two high-pressure feed lines which allows changing of used cylinders without interruption of the diving operation. Shut off valves allow the isolation of each diver’s air supply. The Communication Set is a multipurpose intercommunication system that provides reliable and clear communications between a topside operator (tender) and one or more surface-supported divers, diving bells, personnel transfer capsules (PTC)s, recompression chambers, or other submersible systems.The lightweight, high impact polyethylene plastic case features double wall construction and extra thick corners ensure exceptional strength and a long work life. An O-ring seal protects hardware from moisture when the case is closed. All latches are stainless steel for maximum work life.
A) The Communication Set
A multipurpose intercommunication system that provides reliable and clear communications.
B) Depth Gauge/Pneumo Systems
Dual reading gauges are accurate to + 1/4 of 1% of scale, continuously monitoring the diver’s depths from 0-250 FSW (0-78 MSW). Maximum recommended user depth: 130 FSW.
C) Depth Monitoring/Pneumo Knob
Used to meter the flow of air used for depth measurement.
D) The Stainless Steel Air Outlets
Fittings connect the diver’s air supply hose and depth monitoring/pneumo hose to the KMACS, providing a strong, reliable, corrosion resistant connection. Shut-off valves allow the isolation of one diver’s air supply from the other.
E) Regulator Adjustment Knob
Controls the air pressure delivered to the diver’s umbilical. Variable pressure settings from 115 P.S.I. to 225 P.S.I. are obtainable.
F) Selector Valve Handle
Used to choose either one of the air supply cylinders. Individual cylinders may be changed out with no interruption of the dive.
G) High Pressure (HP) Supply Gauges
Directly monitor the pressure in each of the air supply cylinders.
H) Low pressure Air Supply Fitting
Allows a low pressure compressor to be used as the primary air source. Low Pressure Supply Max. 225 P.S.I.
I) Umbilical Pressure Gauge
Provides a constant reading of the pressure in the diver’s umbilical. The scale on the gauge is 0-300 P.S.I. (0-20 Bar). Recommended umbilical pressure range 150-225 P.S.I.
J) High Pressure Air Supply Yokes with DIN fittings
Each yoke has a bleeder valve for rapid cylinder changing.
H. P. Supply Max. 4500 P.S.I. (300 Bars)
