On-Board Oxygen Generating System (OBOGS)

On-Board Oxygen Generating System (OBOGS)

On-Board Oxygen Generating System (OBOGS) centric Life Support System to provide enhanced physiology protection to aircrew of high altitude and high speed fighter aircrafts. OBOGS replaces Liquid Oxygen System (LOX) by utilizing bleed air from the aircraft engine and separating its components using molecular sieve (Zeolite) Pressure Swing Adsorption (PSA) technology. The system consists of two molecular sieve beds with oxygen plenum to provide breathing gas to aircrew continuously.

Salient Features

  • LoadTwo bed OBOGS to meet breathing requirements of single and twin crew aircrafts
  • Backup Oxygen System (BOS) to provide 40 minutes of breathing oxygen
  • Emergency Oxygen System (EOS) to provide 7 minutes of breathing oxygen
  • Automatic backup and emergency oxygen selection
