📐 ACGIH Ventilation (Minimum Conveying Velocity 3,500-4,500 FPM, Static Balancing)

Industrial Ductwork Conveying Velocity Calculator

Calculate minimum transport conveying velocity (FPM) and duct diameter (Inches) for industrial pneumatic dust collection systems under ACGIH Industrial Ventilation Manual: maintain minimum velocity (3,500 FPM for sawdust/grain, 4,500 FPM for heavy metal grinding dust) to prevent duct settlement plugging, and sheet metal contracting yields.
