Perhaps fan hot air in both directions around article (7)
I believe the answer is:
rotator
'perhaps fan' is the definition.
(something which rotates)
'hot air in both directions around article' is the wordplay.
I cannot really see how this works, but
'around' could be 'o' (I've seen this in other clues) and 'o' is present in the answer.
'article' could be 'tat' (I have seen 'Shoddy article' mean 'tat' so perhaps 'article' could also mean 'tat') and 'tat' is located in the answer.
This explanation may well be incorrect...
(Other definitions for rotator that I've seen before include "anatomical drawing may reveal such muscle" , "Something that turns" , "Muscle that turns" , "Muscle that revolves a part of the body on its axis" , "this one is for turning" .)
