Revolving apparatus for fans? (9)
I believe the answer is:
turnstile
'revolving apparatus' is the definition.
The answer and definition can be both man-made objects as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for turnstile that I've seen before include "Mechanical entry gate" , "Gate admitting one at a time" , "Pivoting gate, to football grounds say" , "Admission gate" , "Crowd-controlling gate, at entrance to sports-ground say" .)
