The 0-degree linear diffuser, or diffuser with fixed blades, is designed for use in ceiling spaces where a 30-degree linear diffuser cannot be installed. This type can serve as a substitute, directing airflow straight to the farthest point in the room.
The 0-degree linear diffuser, due to its uniform and streamlined appearance, is ideal for long installation runs and provides an attractive visual effect in the installation area. This diffuser is commonly used for both supply and return air applications.
