At what pressure do the LPACs typically kick on?

Low Pressure Air Compressors (LPACs) are typically designed to maintain a specific operational pressure range. They activate to ensure that there is adequate pressure available for various pneumatic systems and components within gas turbine systems. The activation pressure is crucial to ensure proper functionality and efficiency in the system.

In many cases, LPACs are set to kick on around 110 psi. This is a standard operating pressure that balances the needs of the equipment while avoiding excessive stress on the compressor itself. By operating at this pressure, LPACs can effectively supply the necessary air for starting the gas turbines, maintaining them during operation, and performing maintenance functions.

Understanding the precise trigger point for LPAC activation helps technicians maintain system integrity and optimizes performance. It ensures that the system has a sufficient air supply without excessive cycling, which can lead to wear and inefficiencies in the compressor.
