PROBLEM TO BE SOLVED: To provide a blowing device for a clean room, having small and compact energy saving construction while greatly reducing its pressure loss by preventing the blowing device itself from generating particulates and omitting the mounting of a filter on the front face of the blowing device. SOLUTION: The blowing device 10 for the clean room for blowing clean air into the clean room 100 comprises a rotating shaft 11 on which an impeller 13 is mounted, a driving source 21 for rotationally driving the rotating shaft, and bearings 22, 23, 24 for supporting the rotating shaft rotatably in no contact. The filter is not arranged on the front face of the impeller. The blowing device has the rotating shaft 11 on which the impeller 13 is mounted, supported (journaled) in no contact when rotated. The rotating shaft is rotationally driven and avoided from sliding to a casing side, preventing the flow of particulates and gas contaminants generated from grease into the clean room 100.
