CONFORMS TO D.O.T. REGULATIONS. 898 Series cylinder and regulator assemblies are self-con- tained, high pressure fixed oxygen sources that supply reduced pressure aviation grade oxygen (per Military Specification MIL-PRF-27210, Type I) to crew members and passengers. Each 898 consists of a cylinder on which a manually operated regulator is installed. Cylinders are either a composite (Kevlar fiber-wrapped aluminum) or steel construc- tion. The number of and size of the cylinders selected will be determined by applica- ble FAR's, number of passengers and the general flight profile of the aircraft. The regulator reduces high pressure oxygen, stored in the cylinder, to a lower pressure suitable for use with orifice-type or demand-type mask assemblies. Regulators are either of a toggle-type or lever-type. Typically, the toggle-type regulators are used for applications where the oxygen system remains in the "ON" position while the lever- type regulators are attached to a cable system for remote ON/OFF actuation. The number of cylinder and regulator assemblies and the correct cylinder size required are determined by applicable FARs, number of passengers, and the general flight profile of the aircraft. Each part number contains 9 digits (excluding hyphens), made of four sections, as described below.
