🪥 Airlock Leakage (Rotary Airlock Valve Seal, False Air Leakage <5.0% CFM)

Pneumatic Classifier Rotary Airlock Leakage Calculator

Size heavy-duty rotary airlock feeder valves sealing negative-pressure air classifier coarse discharge hoppers: calculate parasitic false air infiltration ($Q_{leak} < 5.0% ext{ of classifier airflow}$ @ $0.10 ext{ mm}$ rotor tip clearances), prevent classification cut-point degradation, and pneumatic efficiency yields.
