PROBLEM TO BE SOLVED: To solve a problem in a filter part attached to a conventional centrifugal fan motor that the fan motor is integrally molded with a unit case forming a profile of the fan motor and a supporting member is used for the filter part, so that a suction pressure loss is generated.SOLUTION: In a filter part, a coarse mesh filter low in air resistance is used as a filter and a detachment and attachment mechanism is provided to facilitate to clean dust or contaminant that flows in an air path of a fan motor and adheres to a fan, so that a centrifugal fan motor driving device smaller in suction pressure loss and facilitating maintenance is provided. |
