Cobham designs, develops, and manufactures hardware required in state-of-the-art oxygen systems used in military and commercial aviation applications. Cobham currently manufactures a variety of products ranging from liquid oxygen converters to high pressure reducers to the demand breathing regulators worn by aircrew on their chests or mounted within panels in the cockpit. Cobham also manufactures emergency oxygen systems required when the primary oxygen supply fails as well as oxygen systems for use during emergency egress from the aircraft.
The CRU-103 Chest Mounted Oxygen Regulator (part number F241-2300-5) senses and accounts for changes in altitude and G-levels and regulates oxygen to an aircrew member. The unit, originally designed for the US Navy Combat Edge program, has since become the standard for use in all US Navy chest mounted applications.
The CRU-121 Panel Mounted Oxygen Regulator (part number F241-2400-11/21/31) is a positive pressure oxygen regulator for use with either liquid or gaseous oxygen. It's design, based on the CRU-103, and reduced parts count make this an extremely reliable and easily supported oxygen regulator.
The 1552 Series Potable Water Pressure Regulator pressurizes potable water systems on commercial aircraft. This regulator is adaptable for other pneumatic systems requiring precise pressure control in a compact and lightweight unit.
The Centralized Flow Control Unit (CFCU) (part number B43680-1) is an integral part of an airplane's gaseous passenger oxygen system. The altitude sensing, high flow pressure regulator provides precise oxygen flow to all passenger masks in the event of decompression. Designed and qualified as part of an ATA 35 certified oxygen system, it is capable of supplying oxygen for up to 102 TSO C64a passenger masks.
The Centralized Flow Control Unit (CFCU) (part number B43350-1) altitude sensing, high flow pressure regulator has been designed and qualified as part of an ATA 35 certified oxygen system and is capable of supplying oxygen for up to 556 TSO C64a passenger masks.
The Oxygen Pressure Regulator (part number F103D000-15) takes oxygen from a high pressure gaseous source and reduces the pressure to a suitable range for operation with a panel mounted regulator. It has been qualified for use and is used as OEM equipment on the P-3 Orion Maritime Surveillance Aircraft.
The Oxygen Pressure Reducer (part number B43575-1), qualified for use on commercial aircraft, is an integral part of a gaseous aircraft emergency passenger oxygen system. The valve mounts directly to the cylinder and hand valve, and provides a regulated pressure supply to an altitude compensated centralized flow control unit for distribution to the masks.
The Oxygen Pressure Reducer (part number B45526-1), includes a pressure transducer for remote system pressure readings. The valve mounts directly to an oxygen cylinder and valve assembly and provides a regulated pressure supply to the altitude compensated pressure regulator.
The high pressure Passenger/Crew Oxygen Regulator (part number B19925) consists of an oxygen pressure reducing regulator with an integral high-pressure reducer. It is used to convert high-pressure oxygen to a lower, manageable pressure for use in aircraft emergency oxygen systems.
Currently under development:
The Chest Mounted Diluter Demand Regulator (CMDDR) (part number B44560-1) supplies oxygen at either 100% or diluted with air as selected by the user, in any environment where user-mounted, lightweight system mobility is required.
The General Aviation (GA) Mask and Regulator Assembly represents the next generation in general aviation oxygen equipment. When combined with standard oxygen supplies, the new system is a breakthrough in comfort and performance.
The Electro-Mechanical Valve and Regulator (EMVR) (part number B47875) is an integrated on/off valve-pressure regulator that is electrically actuated from a remote location such as the cockpit of an airplane. The EMVR is adaptable to a variety of high pressure applications.
