Industrial Dust Collection Vacuum System Audits


Industrial vacuum systems are a challenge to optimize. They have more distribution system variables to balance than a compressed air system does. Vacuum systems conveying particulate are sensitive to velocity. If the velocity is too high, pressure drop results. If it’s too low, particulate doesn’t stay in suspension, and there can be compliance and safety problems. For instance, when conveying wood or other explosive dust, dropping below “critical” velocity allows dust to accumulate in the bottom of the duct, creating an explosive hazard.
