Step-by-Step Guide: Sizing Your Engineering Unit Air Requirements
Industrial air compressor sizing is based on actual operating demand rather than total installed machinery capacity. The objective is to match airflow supply with real-time consumption while accounting for usage variation, leakage, and system losses.
Total Effective Air Demand (CFM)
Sum only machines expected to run simultaneously during peak operation.
Duty Cycle Adjustment
Apply operating factor based on real usage patterns (typically 0.5–0.85 depending on tool type and process intensity)
System Efficiency Margin
Add 20–25% buffer for leakage, expansion, and future load increase
Pressure Drop Compensation
Account for 10–15 PSI loss across dryers, filters, and piping networks
