The present invention concerns a rotary compressor for compressing a gaseous medium, comprising an impeller (2), a drive unit (3) and a magnetic coupling (4) comprising a rotating inner rotor (41), a rotating outer rotor (42) and a can (40), wherein the inner rotor (41) is connected to the impeller (2), wherein the impeller (2) comprises a continuous solid portion (25), wherein a first row (21) and a second row (22) of blades (23) are provided at the outer circumference of the solid portion (25) of the impeller, the first and second row of blades being separated by a circumferential middle wall (20), and wherein the blades (23) of the first row (21) are offset in circumferential direction relative to the blades (23) of the second row (22). La presente invención se refiere a un compresor giratorio para comprimir un medio gaseoso, que comprende un impulsor (2), una unidad de accionamiento (3) y un acoplamiento magnético (4) que comprende un rotor interior giratorio (41), un rotor exterior giratorio (42) y un recipiente (40), en donde el rotor interior (41) se conecta al impulsor (2) , en donde el impulsor (2) comprende una porción sólida continúa (25), en donde una primer fila (21) y una segunda fila (22) de cuchillas (23) se proporcionan en la circunferencia exterior de la porción sólida (25) del impulsor, la primer y segunda fila de cuchillas separándose por una pared intermedia circunferencial (20), y en donde las cuchillas (23) de la primer fila (21) se desplazan en dirección circunferencial relativa a las cuchillas (23) de la segunda fila (22).
