The KMACS 5 controls 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. It is available with or withour 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.
Communication Set: A multi-purpose intercommunication system that provides reliable and clear communications
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.
Depth Monitoring/Pneumo Knob: Used to meter the flow of air used for depth measurement.
Stainless Steel Air Outlet 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.
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.
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.
High Pressure (HP) Supply Gauges: Directly monitors the pressure in each of the air supply cylinders.
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.
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.
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)
Shut-off Valve: Controls the air supply to both divers. When the valve handle is up (vertical) the valve is open. When the valve handle is down (horizontal) the valve is closed.
Weight (with communications): 57 pounds
Weight (no communications): 46 pounds
Outer Dimensions: Length = 21 inches, Height = 17 1/2 inches
Operational Specifications & Limitations Use: For SS Air diving only. Pure oxygen MUST NOT be used. Compressed air from high pressure tanks (scuba or other types of compressed air tanks), or from a compressor should be the only supply to the KMACS 5.
