What is the best operating range for all dynamic compressors?

The best operating range for all dynamic compressors is found between the surge point and the stonewall point. This range is crucial because it ensures that the compressor operates efficiently and reliably.

Operating above the surge point allows the compressor to avoid unstable flow conditions, which can lead to performance issues and potential damage. The surge point represents the minimum flow at which the compressor can operate without experiencing stall conditions.

On the upper end, the stonewall point provides a limit where the compressor operates at maximum capacity. Operating near or at this point can lead to continuous operation without damaging the equipment, provided that the compressor is designed to handle such loads.

Thus, maintaining operation within this range maximizes compressor efficiency and performance, ensuring that airflow and pressure are optimal and reducing the risk of operational hazards.
