There is provided a compressor device in which resonance in a circulating channel is reduced so that an increase in noise generated from the compressor device is prevented. The compressor device includes: a plurality of blades rotated about a rotation axis; an air inlet (4) extending along the rotation axis and introducing air to the blades; a circulating channel (5) disposed on a circumference centered on the rotation axis and communicating between the air inlet (4) and the shroud of the blades; and a strut (9) extending radially centered on the rotation axis and dividing the circulating channel. Resonance frequencies determined from circumferential lengths in the circulating channels (5) divided by the strut (9) are higher than a noise frequency determined from the rotational speed of the blades and the number of blades. |
