The volume flow rate can be set using an external scale quickly and easily with no tools required. The units have high control accuracy and no on-site test measurements are required for commissioning. Suitable for airflow velocities of up to 12 m/s, the RN Series is suitable for any installation orientation. For special applications RN Series can be optionally fitted with actuators.
