📊 ISO 14644-4 Pressure Cascade (12.5 Pa / 0.05" WC Differential), Airflow Locks

Cleanroom Differential Pressure Cascade Calculator

Model multi-suite positive and negative differential pressure cascades across cleanrooms, airlocks, and gowning anterooms under ISO 14644-4: calculate step-down pressure differentials (10.0 to 15.0 Pascals / 0.04" to 0.06" WC per barrier preventing cross-contamination), door crack air leakage CFM, and cleanroom controls margins.
