KQ42 series units are square panel nozzle diffusers. Nozzles are arranged in concentric squares and can be oriented individually. They can be used for both supply and extraction of air and for installation in the ceiling.
These diffusers are used wherever a neat design is required and ease of installation and adjustment of the throw is appreciated.
