Diffusers
DAL359
swirl diffuser with radial air outlet openings, round or squareOverview
The DAL359 is available both as a round and square unit. It can be installed in existing ceiling grids and also be free-hanging. Even at low ceiling heights, the diffuser meets all comfort requirements.
The air guide elements enable the form of the air stream to be deflected both acoustically and aerodynamically. The flow direction can be subsequently adjusted at any time even when installed.
The high number of air guide elements provides for the draught-free dissipation of high cooling loads, so that the swirl outlet can also be used with low ceiling heights.
The DAL 359 thus generates a low pressure loss on account of its air flow-optimised air guidance elements and thus achieves high air flows at low sound power levels.
The one-sided discharge direction is achieved by the opposing adjustment of all the rollers of the one half to the other half of the air outlet.
A two-sided air stream from the ceiling is achieved by the opposing roller adjustment of two quarter-circle segments.
In the default setting, the eccentric rollers generate a rotating air stream from the ceiling with a swirl component and thus an associated high level of induction.
