An anti-rotation fin-fan device for use in refinery processes is provided to overcome the problems of windmilling when the fin-fan is non-operational. The invention provides a one-way clutch on the vertical shaft of a fin-fan to prevent backward rotation of the fin-fan thereby reducing stresses to the fin-fan systemduring start-up. The invention also provides a clutch adaptor to enable attachment of the one-way clutch to a variety of fin-fan installations as well as a locking system to decrease the risk of injury during maintenance operations.
