By default, swirl diffusers are white in colour. Their blades have distinctive preparations for various airflow patterns. Swirl diffusers can be mounted at destinations the same as directional diffusers and round diffusers. Nevertheless, swirl diffusers are not as likely to get noticed in lowend office structures and lodges because of the higher Value.
