SRA81 Spring Reset Damper Actuator
Models:
SRA81
Torque:
5 Nm
Suitable Damper Size:
Under normal wind resistance, 1 Nm matches 0.1 square meter (including closed valve matching scheme)
IP Grade:
IP54
Utilizes an imported DC motor/brushless motor to deliver torques of 5NM, ensuring robust performance and durability. Designed for building ventilation fields, it facilitates mechanical reset upon power failure and electric start, capable of enduring more than 30,000 cycles of repeated action.
