Ceiling diffusers
KQ1 – KQ1R

Back to Diffusion

The KQ1 series units are slot diffusers on square or circular panels. The slots are arranged in a "star" pattern and have adjustable deflectors. They can be used for both supply and extraction of air and for installation in the ceiling.
The version with a square panel is particularly suitable for installation in modular ceilings.
The circular panel version is frequently used in irregularly shaped rooms, providing a better aesthetic result.
These diffusers are used wherever a neat design is required and ease of installation and adjustment of the throw is appreciated.
