These circular ceiling- or duct-mounted diffusers are engineered to deliver high air induction and manage large airflow volumes while maintaining low noise levels for both supply and return air applications. Their performance makes them ideal for spacious environments such as auditoriums, airport halls, supermarkets, and industrial facilities.
Round diffusers are known for their durability and are widely used in heating, ventilation, and air-conditioning systems. They ensure exceptionally even 360-degree horizontal air distribution.
Designed for use in both commercial and industrial ventilation and cooling systems, these diffusers provide broad and efficient air dispersion. They can be fitted into suspended ceilings or installed directly onto exposed ductwork. Their design offers effective supply and exhaust airflow, making them well-suited for offices, retail spaces, and similar locations where controlled air patterns are important—especially for cold air delivery.
Our aluminium round diffusers are manufactured for optimum performance, quiet operation, and reliability in all HVAC applications. They can handle substantial airflow at minimal sound levels, making them ideal for variable air volume systems.
Round diffusers also serve as an aesthetic option for designers, supplying draft-free airflow to conditioned spaces. The easily detachable core not only simplifies installation and maintenance but also enhances the visual appearance by removing the need for visible screws.
Plenum boxes are available with either top or side entry connections, and can be fitted with volume control dampers when required.
