PROBLEM TO BE SOLVED: To provide a multi-functional back-flow type powerful suction blower reducing energy consumption and achieving large air volume, large capacity of handling contaminants, high efficiency, multi-functionality, and low-noise, and reducing a risk of contamination and erosion of through-flow parts in a housing. SOLUTION: The multi-functional back-flow type powerful suction blower includes the casing 1, an impeller 2, impeller blades 3, a back-flow suction port 4 and a side-wall air outlet 5, The back-flow suction port 4 arranged in the axial side wall of the casing 1 faces the axial side surface of the impeller 2, and a suction side separating plate 6 is arranged in the edge of the impeller blade 3.
