How to Calculate Compressor Compression Ratio and Why It’s Critical for Your Pneumatic System Efficiency?
This article explains how to calculate compressor compression ratio using absolute pressures, covering the formula CR = P_discharge/P_inlet, altitude corrections, and multi-stage design. It details optimal compression ratio ranges for reciprocating, rotary screw, and centrifugal compressors, and quantifies how excess ratios increase energy costs by 30–50% and reduce equipment life in pneumatic systems.
