FIELD: machine building.
SUBSTANCE: invention relates to machine building, more specifically, to turbo compressors. Flow-through centrifugal compressor comprises fixed casing with attachment flanges, inside it centrifugal wheel is arranged, mounted on electric motor rotor, which stator is fixed in casing trunnions, its casing is also made detachable in form of truncated ellipse in cross-section, centrifugal wheel is attached to rotor casing with brackets, and its blades follow casing outline along their length and also have screw bending relative to longitudinal axis and around it with provision of minimum gap between casing and blades and by their length occupy half and more than length of compressor inner cavity, which remaining part serves as diffuser.
EFFECT: use of disclosed compressor allows to reduce its dimensions, increase air supply controllability, increase gas volumetric flow rate.
