💨 ACGIH Industrial Ventilation (Minimum 3,500-4,500 FPM), Static Drop in. WC

Industrial Ductwork Velocity & Static Pressure Calculator

Size round spiral and clamped industrial dust collection ductwork under ACGIH guidelines: calculate duct diameter to maintain critical conveying velocities (3,500 FPM for fine dust to 4,500 FPM for heavy metal grinding dust preventing line settling), friction and branch elbow loss (inches Water Column), and duct contractor margins.
