This blower package is used for agitation at a plant that manufactures aluminum electrode foil. Since it was replacing existing equipment, care was taken to provide equipment that would not only match the system specs like RPMs, horsepower, and pressure, but that would also have the same type of lubrication needs and maintenance schedule for minimal disturbance to the operating team
