The DW-V2 with a hidden twist element at the inlet. The jet rotates and the throw is roughly halved, for rooms where a plain nozzle would reach too far.

Technical data ↓

How the DW-V2-DR works.

The DW-V2 with a hidden twist element at the inlet. The jet rotates and the throw is roughly halved, for rooms where a plain nozzle would reach too far.

Applications: long narrow rooms; combined with jet nozzles for high flows or a uniform appearance (p. 2).
