The Shadowline Diffuser is nearly invisible once installed and effectively channels air through the ventilation system.

The Shadowline Diffuser is designed to work with a ducted (or inline) ventilation system. When installed the product sits behind the ceiling sheet at the junction of a wall and ceiling making the ventilation system almost invisible.
