Square swirl diffuser with adjustable bars that can be used for
both supply and extract air. The swirl pattern ensures high induction
and a large dynamic range. It is therefore ideal for the horizontal
supply of very cold air. The diffuser can also be set to a vertical
supply air pattern, enabling supply of heated air. The diffuser is
supplied as standard with inward swirl. For extract, the diffuser is
supplied as standard without bars.
