Can be used for supply or return air, the design of these ceiling diffusers accepts air from surrounding surfaces and not directly below. This makes it ideal for heat, smoke and vapour extraction/transfer. For desired airflow control, simply screw the inverted cone centre. To "shut offf" flow -the cone can be fully wound in.
