ECO Plastic round ceiling Diffuser – Modern Mechanical Design Limited

– $145 Price range through $145

Eco Plastic Diffusers are easy to install with plastic clips and a cutout template. They feature a spinning cone for airflow adjustment, while the automatic model uses a thermal spring to direct air—downwards for heating and towards the ceiling for cooling. The ECO Automatic 150 lacks a thermal spring due to low airflow but includes a sleek perforated plate. Simple installation: cut the ceiling, connect the duct, and snap the diffuser in place.
