The variable swirling tuyere has the characteristics of large induction ratio and rapid attenuation of wind speed. It can be used as a large air volume and large temperature difference air supply in the air conditioning ventilation system to reduce the number of air outlets. It can be installed on the ceiling or ceiling and can be used for low space within 3 meters. It can also be used to supply air in two large areas with a height of up to 10 meters.

Adjusting the position of the spinner in the tuyere can obtain different airflow types such as blow-out type and diffuse type, and the wind speed is basically unchanged.
