What is Oxygen and why it’s important?
A person can continue his life by breathing at a concentration of 21% oxygen. Breathing is the only process in which oxygen is needed. Gas exchange occurs between the lung alveoli and blood in the lung capillaries by passive diffusion of gases.

Dissolved gases in the blood spread throughout the body through the circulatory system by pumping blood through the heart.

With increasing altitude, air pressure and oxygen pressure decrease proportionally and getting oxygen becomes increasingly difficult.
At higher altitudes, this causes a condition in the bloodstream that leads to insufficient oxygen, hypoxia, and death.

What is hypoxia?
Hypoxia is the reduction of the oxygen rate in the body tissues. The reduction of oxygen is a big concern for pilots and professions in smiliar environment.

At an altitude of 3,000 meters, it causes symptoms such as increased breathing depth and heart rate, and headache dizziness.

Over 5,000 meters of judgment is impaired and visual impairments become serious. Loss of consciousness occurs between 6,400 and 7,000 m and oxygen must be given rapidly.

To prevent hypoxia in air travel, the rule is to keep the oxygen pressure value equal to sea level.

What is OBOGS?
These are the systems that allow an aircraft to produce its own oxygen during a flight.

Also, OBOGS systems hold nitrogen gas when air is passed through it, thus increasing the oxygen rate.

Zeolite material in the OBOGS system works like a molecular sieve and increases the oxygen concentration.

Compared to LOX and GOX system, OBOGS has many advantages.

  • It does not need stock and warehouse maintenance.
  • OBOGS has no daily service conditions and planned preventive maintenance takes place in 2000 hours.
  • It does not need storage and moving, it produces oxygen from its environment.
  • There is no potential for accidents due to high-pressure gases.
The Heart of the OBOGS System, is the controllers that provide the desired oxygen concentration to the pilot at the height of the aircraft and are responsible for listing the processing of the concentrator bearings.

The oxygen concentration of the air exiting the OBOGS unit is constantly monitored and its operation is adjusted to remain within certain physiological limits.

Monitoring and monitor operation is performed using paramagnetic oxygen detection technology.

The monitor is divided in such a way that the malfunction of the controller and its concentration detection element cannot compromise the safety of the system.

In the event of a fault, OBOGS reaches the maximum setting of usage. Active protocols and mulfunction black box can be found in case of malfunction inside the OBOGS unit.
