About this product
The Cabin Pressure Controller 20791-02AB is an aircraft avionics component responsible for monitoring and regulating cabin pressure throughout different flight phases. It ensures that the air pressure inside the aircraft remains within safe and comfortable limits, automatically adjusting based on external altitude changes. The controller plays a crucial role in preventing rapid decompression and optimizing oxygen levels to enhance passenger safety and well-being.

PRODUCT DESCRIPTION

20791-02AB

  • Automated Pressure Adjustment – The controller monitors atmospheric changes in real-time and seamlessly adjusts cabin pressure to prevent sudden variations, ensuring passenger comfort and crew efficiency.

  • Integrated Avionics Compatibility – Designed to work with modern flight management and avionics systems, it provides real-time pressure readings to pilots via cockpit display panels, aiding in precise environmental control.

  • Safety and Redundancy Features – Built with multiple fail-safe mechanisms, it automatically detects pressure inconsistencies and engages backup modes in case of primary system failure, minimizing risk during flight.

  • High-Durability Aerospace Construction – Manufactured using aerospace-grade materials, this unit is designed to withstand high-altitude operational stress, vibrations, and temperature fluctuations while maintaining long-term functionality.


  • Used in passenger airliners to maintain a comfortable cabin environment regardless of changes in altitude.

  • Helps optimize oxygen levels in corporate and VIP aircraft, ensuring a smooth and safe flying experience.

  • Plays a vital role in transport and defense aviation, where stable cabin pressure is crucial for crew performance and equipment functionality.

  • Prevents excessive pressure differentials that could stress the fuselage and cabin walls, preserving the aircraft’s structural integrity.

  • Is this unit compatible with all aircraft models?

The 20791-02AB model is designed for specific aircraft types. It is recommended to check with the aircraft manufacturer or maintenance provider to verify compatibility before purchase.

  • How often should the Cabin Pressure Controller be inspected or replaced?

Regular maintenance and calibration checks are required based on the aircraft’s maintenance schedule. Typically, inspections occur during C-checks or D-checks to ensure continued operational efficiency.

  • What happens if the Cabin Pressure Controller malfunctions during flight?

In the event of a failure, the aircraft’s backup manual pressure control system can be engaged by the pilot, allowing for a controlled descent or diversion to a lower altitude.
