Up one level
Our commercial products include pressure vessel and valve assemblies, emergency oxygen regulators for passengers and crew and high pressure oxygen fill valves which insure safe ground filling of oxygen storage systems.
Most commercial transport aircraft which fly above 10,000 feet are required to incorporate emergency oxygen systems for the crew and passengers. Most crew oxygen systems store oxygen at 1850 psi in steel or composite cylinder and valve assemblies. An oxygen pressure regulator is used to reduce this pressure to about 70 psi for delivery to the crewmembers through a panel or mask mounted breathing regulator. Some of the larger commercial aircraft also carry passenger oxygen in multiple cylinder and valve assemblies. In such systems, a pressure reducer decreases supply pressure to 600 psi for delivery to flow control units which supply the passenger oxygen masks.
Below is an example of a typical oxygen system.
Among the products Carleton manufactures for commercial aircraft oxygen supply systems are:
