What is a Round Ceiling Diffuser?
A round ceiling diffuser is an air terminal device used to distribute or extract air evenly within a room. It connects to a duct system and helps control airflow patterns to avoid draughts while improving overall air circulation.
How Does It Work?
Air is supplied or extracted through the diffuser face, which is designed to spread airflow in a controlled radial pattern. The removable central core allows for easy adjustment, maintenance, and access to components such as volume control dampers located behind the diffuser.
