Press more air out (7)
I believe the answer is:
armoire
'press' is the definition.
(armoire is a kind of press)
'more air out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'more'+'air'='moreair'
'moreair' anagrammed gives 'ARMOIRE'.
(Other definitions for armoire that I've seen before include "Large wardrobe or cabinet" , "Cabinet originally used for storing weapons" , "Large wardrobe - more air (anag)" , "item of furniture" , "Cupboard" .)
