Greenheck recently redesigned its AMD line of Air Measuring Dampers that combine an accurate airflow measuring station and a low leakage control damper into one compact unit. The differential pressure Air Measuring Station (AMS) now includes extruded aluminum air measuring tubes instead of galvanized steel for a sleeker design. The AMD damper series comes standard with a modulating actuator and a properly sized pressure transducer that output a signal proportional to CFM. By adding a factory-supplied controller, such as Greenheck’s Vari-Green® constant volume controller, AMD series airflow measuring dampers become a turnkey solution for measuring and controlling the flow of air For more information about Greenheck products, visit www.greenheck.com.
