Suitable for installation on ceilings of large spaces. It can automatically sense the supply air temperature and switch the airflow distribution mode automatically in winter and summer.
In summer, the built-in blades open to form a vortex airflow for full-area air discharge.
In winter, the built-in blades close, and hot air is discharged only from the central cylinder to achieve a longer air supply distance, solving the problem that hot air is difficult to flow downward.
The temperature-sensing actuator requires no power supply, featuring energy saving, environmental friendliness, maintenance-free operation, stable performance and intelligent control.
Specification: Neck sizes Φ200, Φ250, Φ300, Φ350, Φ400, Φ450, Φ500.
Custom types: Manual type, electric type, temperature-sensing type.
