BKP-2-2-210
Portable Oxygen Supply Unit
Description
BKP-2-2-210 portable oxygen supply unit
The BKP-2-2-210 is a portable aircraft oxygen supply unit used for breathing support in civil aircraft oxygen systems. It is intended for situations where crew members need an independent oxygen source outside their normal workstation, for example while moving through a smoke-filled cabin or assisting passengers. The unit may also be used for emergency or therapeutic oxygen supply, depending on the aircraft procedure and the connected oxygen mask. Its compact cylinder-and-reducer layout allows the block to be handled as a separate portable item rather than as a fixed aircraft oxygen installation.

Crew and passenger use of BKP-2-2-210
In aircraft operation, the BKP-2-2-210 gives the crew a mobile oxygen source for short-term tasks away from the cockpit. This can be important during smoke, fumes, cabin depressurization-related procedures, or when assistance must be provided in the passenger cabin. The unit is also suitable for connecting oxygen masks used for crew or passenger support, provided the mask type is approved for the particular aircraft system. On aircraft such as Tu-154M and L-410, portable oxygen blocks of this class are normally treated as onboard emergency and service equipment.
BKP-2-2-210 cylinder and reducer assembly
The unit consists of a small oxygen cylinder and a shut-off / pressure-reducing assembly. The reducer section brings cylinder pressure down to the required outlet pressure for connected oxygen equipment. The assembly also includes a pressure gauge for checking cylinder pressure, a filling connection with a check valve, a safety valve, and outlet fittings for mask connection. This layout lets maintenance personnel check the charge state, refill the cylinder through the specified port, and connect the block to approved mask equipment without changing the basic unit design.
Oxygen delivery through the BKP-2-2-210 block
The BKP-2-2-210 is designed to deliver oxygen at a stable outlet pressure and with sufficient flow for breathing equipment. According to the passport data, the unit maintains its specified delivery performance over the stated cylinder pressure range. This is important because the block must continue to provide usable oxygen flow as cylinder pressure decreases during operation. The pressure-reducing system prevents full cylinder pressure from being supplied directly to the mask line, while the outlet fittings allow connection to compatible masks or oxygen breathing devices.
Aircraft masks used with BKP-2-2-210
The BKP-2-2-210 can be used with aircraft oxygen masks such as KM-114, MKP-1T and DKM-1, depending on aircraft documentation and the required operating configuration. Since the unit has outlet fittings for mask connection, the actual set used on board should be checked against the aircraft equipment list and maintenance manual. For supply purposes, it is important to clarify whether the requirement is only for the oxygen block itself or for a complete set including masks, hoses, operating instructions, and aircraft-specific accessories.
Operating conditions and storage of BKP-2-2-210
The BKP-2-2-210 is built as aircraft oxygen equipment and is specified for controlled service conditions, including temperature effects, vibration, humidity exposure, and aircraft load factors. Passport data also define service life, overhaul intervals, storage conditions, and warranty-related information. These details matter because oxygen equipment cannot be judged only by external appearance. Before installation or onboard use, the block should be checked for cylinder condition, pressure gauge condition, reducer serviceability, filling port condition, leakage, documentation status, and remaining life limits.
Identification and supply of BKP-2-2-210
For procurement or replacement, the full designation BKP-2-2-210 should be stated together with the required condition and documentation. The passport identifies the unit as an oxygen supply block and includes its individual serial number, acceptance records, technical data, completeness information, resource, storage and preservation notes. Depending on stock, the unit may be supplied as new production, from storage, or after inspection / overhaul. For aircraft use, the supplier should confirm passport availability, pressure test or service status, oxygen cleanliness requirements, and compatibility with the target aircraft.
