Ceiling swirl diffuser DQJSL Description The ceiling swirl diffuser DQJSL-... is suitable in particular for use in rooms up to a height of 4 m. The blades can be adjusted to achieve a horizontal as well as a vertical throw pattern. This swirl diffusers ensure optimal air distribution in heating and cooling. Individual areas can be shielded by setting the blades to a certain position. This may become necessary if obstacles obstruct the air flow. The adjustable blades have the shape of support profiles. The air guiding blades are aerodynamic thus giving the diffuser its low noise qualities and...
