WR400

Circular swirl diffuser with fixed blades

The swirl diffuser type WR400 is equipped with fixed blades. It is designed for exposed duct mounting but can also be surface mounted. A high induction is obtained through the excellent swirl effect. The diffuser has a strong coanda effect over a wide temperature range (also at low flow rates) which makes it optimally suited for VAV applications.
