The Shadowline Diffuser Round is a flangeless internal ceiling grille that sits flush with the ceiling, allowing air to be channelled through ventilation systems. The diffuser has a round profile with a centre panel that is ready for painting, resulting in a discreet finish that matches the ceiling. Designed in Australia by Expella, it has been engineered to optimise airflow and efficiency.
