The Air Measuring Damper (AMD) Series combines an accurate airflow measuring station and a low leakage damper into one compact assembly that both measures and regulates airflow volumes to a target set point. The damper series is compatible with a field-supplied controller or a factory-supplied LON controller. The series includes four models: AMD-23, featuring a 3-V blade control damper; AMD-33, incorporating a fabricated airfoil blade control damper; AMD-42, constructed with an extruded airfoil blade control damper; and AMD-42V, featuring a vertical extruded airfoil blade control damper.
