Abstract (en)
In known fan blade has a base body (2; 12) with a front edge (7; 17), which front edge is at least partially formed by an edge complementary member (6). In order to provide a fan blade for use in environments with dust-containing or droplet-containing gases, which is has a long service life, so that the downtimes of the plant are reduced, it is suggested that a round groove (5) runs in and along the front edge (7; 17), and in that the edge complementary member is formed as a round bar (6) which is inserted in the round groove (5).
