WR230

Circular swirl diffuser with fixed blades and diffuser ring

The swirl diffuser type WR230 is equipped with fixed blades. It is designed for surface mounting but can also be mounted directly on exposed ducts. A high induction is obtained through the excellent swirl effect. The diffuser ring guarantees a strong coanda effect over a wide temperature range (also at low flow rates) which makes it optimally suited for VAV applications.
