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.
Greenheck sources report that the company offers the most UL certified dampers and the largest selection of AMCA licensed dampers in the industry.
