A grease extractor includes a centrifugal fan for forcibly flowing grease laden air in order to remove grease therefrom in cooperation with a trap member. The grease extractor comprises a vessel with an inlet for introduction of the grease laden air and an outlet for discharging clear air. The fan, which has a rotation axis and has a circumferential fan surface, is disposed between the inlet and the outlet to be rotated about a rotation axis so as to generate a forced flow of the air for introducing the grease laden air inwardly and flowing it radially outwardly through the circumferential fan surface. The fan includes impellers which deflects the grease laden air to separate the grease therefrom and coagulate it into corresponding grease particles. Flow converting members are provided on the circumferential fan surface for converting the radial air flow into an axial flow directed outwardly substantially along the rotation axis. The grease trap member is disposed downstream of the fan means and is defined on an interior wall of the vessel radially outwardly of the fan surface such that the grease particles flown radially outwardly by the fan through the fan surface are caused to collide against the trap member and deposit thereon while the flow converting member allows the air passing through the fan surface to deflect axially so as not to be directly radially opposed relation to the fan surface.
