PURPOSE:To achieve a high speed and a large capacity by forming two flow path systems symmetrically in a casing and producing a double flow. CONSTITUTION:A casing 1 is splitted symmetrically into first and second casings 1a, 1b and an inlet casing 7 is formed in the center. A stationary blade 8 is secured to the inner circumference of the first and second casings 1a, 1b and a moving blade 9 is secured to the outer circumference of a rotor 2. The air sucked through the inlet casing 7 passes through the flow paths 10a, 10b and produces a double flow. Consequently, the effective length of the moving blade can be shortened resulting in a high speed and a large capacity.
