The product is airflow-sensitive device with the function of controlling the air flux. When the airflow can’t up to the stated value, the contacts will switch and output controlling signal and switch the circuit. They are suitable for air cooling system, ventilation system or air condition system for wind speed controlling and wind cut protective.
