Bengaluru: Delhi is literally gasping for oxygen. During such a time, the DRDO has set up two oxygen plants in the capital with each of them generating around 1,000 litres of the life-saving gas per minute.

The oxygen plants have been installed at AIIMS and Safdarjung Hospital in New Delhi, as per a report on India Today.

These plants work on the technology that is based on the on-board oxygen generation for light combat Tejas aircraft developed by DRDO. The website adds that the system can cater to 190 patients at a flow rate of 5 litre per minute (LPM) and charge 195 cylinders per day.

OnBoard Oxygen Generating System (OBOGS) 

It is an indigenously built technology (specifically for India-manufactured aircraft) used to supply oxygen to the aircrew by supplying oxygen using bleed air from the engine and separating oxygen from other components, using a process called Pressure Swing Adsorption Technology. 

With this technology the pilot can remain airborne for a long time. Till this time, the pilots had to get to the ground, maybe an hour or so after they were airborne to refill oxygen.

Coming to the DRDO, it has also set up make-shift Covid hospital at multiple locations including Lucknow, Ahmedabad, and Delhi.
