⚙️ Rotary Screw Compressors (100-150 PSI), Delivery (4.2-4.5 SCFM/HP), VSD Efficiency

Commercial Rotary Screw Compressor Calculator

Size industrial oil-flooded rotary screw air compressors (Atlas Copco / Ingersoll Rand / Kaeser): calculate delivered airflow (SCFM = 4.2 to 4.5 SCFM per horsepower at 100-125 PSIG), variable speed drive (VSD) turndown efficiency (saving 30-50% off-peak electricity), air receiver storage tank sizing, and compressed air equipment margins.
