Abstract (en)
In order to overcome the limitations and problems that earlier apparatus have experienced, a fan blade (12) is proposed, said fan blade (12) comprising an interior space (16) and a plurality of holes (26) in fluid communication with said interior space (16) and from which a high pressure cryogenic gas (34) is ejected for cleaning a surface (14) of the fan blade (12). A corresponding self-cleaning fan (10) is also proposed.
