Integrated eccentric rollers

The patented eccentric rollers achieve high volumetric flows at low sound power levels. In addition, the high room air induction ensures that temperature differences are equalized quickly and draughts are avoided.

High induction

The DAL358 has a very high induction ratio thanks to the integrated eccentric rollers. This ensures rapid reduction of temperature differences, allowing small minimum spacing between the diffusers.

Model sizes

The diffuser is operated with a plenum box and is available in both round and square versions in six nominal sizes each from DN 300 to DN 800 .

Version: round
Nominal sizes: DN 300 – DN 800

Version: square
Nominal sizes: DN 300 – DN 800

Design variants

The DAL358 is versatile and can be supplied in both round and square form . It is suitable for installation in existing grid ceilings as well as suspended freely.

Application areas

  • in the comfort zone of office and administration buildings, cleanrooms, department stores or multi-purpose halls
  • suitable for constant as well as variable volumetric flow systems
  • advantageous with variable volumetric flows, as a reduction of the volumetric flow to 30 % is possible without changing the jet pattern and the swirl effect and induction ratio are maintained

Variable air guidance

The air discharge direction of the diffuser can be adjusted as required: For a one-sided air discharge direction, the rollers on one half are set in opposite directions. For a two-sided ceiling jet, the rollers are adjusted in opposite directions on two quarter-circle segments. As standard, the eccentric rollers create a rotating ceiling jet with a swirl component and high induction.
