Honeywell 4074ELR Heavy-Duty Crank Arm

The Honeywell 4074ELR Hevi-Duty Crank Arm is essential part used in several commercial and industrial HVAC systems, that regulating dampers for exact airflow control. This crank arm is a mechanical linkage between the damper actuator and the damper blade. When the actuator is given a signal to change airflow, it rotates and the crank arm translates this rotational motion into linear motion of the damper blade. As such, it permits smooth, accurate modulation of airflow through the HVAC system with better performance and energy efficiency. The crank arm of the 4074ELR is made of robust construction and corrosion resistant materials.
