  • Understanding Conveying Velocities

    It is critical to understand conveying velocities in your dust collection duct system Excessively low or high conveying velocities can each cause undesirable consequences from dust falling out in the duct to excessive duct abrasion and there are economical advantages to optimizing the air volume in the system to ensure the desired conveying velocity You can limit capital costs on the system
