Reinventing the Industrial Blower
, there is a downside: blowers can create noise levels that rival jet engines if not properly designed or enclosed. Therefore, finding an industrial blower package that has been properly designed and optimized to reduce sound output is necessary to prevent dangerous ambient noise levels and sound vibrations

Motor sizing made simple
The proper sizing of three-phase induction motors saves energy and reduces downtime. Load on this blower motor is nearly constant. Conveyor drives in a steel pipe mill take a huge pounding. Hot pipe falls onto a row of rotating conveyor sheaves and the sheaves kick the pipe toward a sizing mandrel
