The device has an open work (4) patterned in a ferrule, and spacer units (3, 3`) integrated to the ferrule and fixedly mounted to a vane part in a non-functioning side through a locking unit. The spacer units include a folded sheet including a flat bar and terminated at ends (20, 20`) by legs (11, 11`, 11``). The legs are positioned along a vane (1) and integrated to the vane by the locking unit. An independent claim is also included for a rectifier stage of a compressor with external and internal ferrules. |
