Rectangular diffusers with adjustable elements
The ZAR-R rectangular diffusers with adjustable elements are used in shops, offices, exhibition halls, and environments that require a specific architectural design. They are designed for installation in false ceilings. Based on how they are manually adjusted, they can be configured as 1 or 2-way diffusers. The Coanda effect and high induction ensure uniform airflow with a temperature differential of up to 12K and flow variation by up to 60%, whilst maintaining a steady stream of air.
