Abstract (en)
A fan particularly for food cooking ovens, comprising a runner (40,140) provided with a ring of vanes (12,112) and with an axial hole (20,120) for keying to a rotation shaft, the runner (40,140) being constituted by two coaxial and adjacent plate-like disks (11a,11b,111a,111b), a ring of vanes (12a,12b,112b) being provided on at least one of the two disks (11a,11b,111b); each one of the vanes (13a,13b,113) is obtained by cutting and bending a portion of a corresponding annular sector (15a,15b,115) of at least one of the two disks (11a,11b,111b). <??>In order to increase the number of vanes, two runners may be sticked together to one conjoined runner as can be seen in fig. 3. The runner in the front (13b) therefore has slots (14b), through which the vanes of the rear runner (13) extend. The number of vanes is thus doubled. <IMAGE>
