AMD-TD airflow-measuring dampers combine the functionality of a thermal dispersion airflow station and a low-leakage control damper.
The AMD-TD series of thermal dispersion-based airflow-measuring dampers combines the functionality of a thermal dispersion airflow station and a control damper to control airflow volumes to a target set point. The AMD-TD series of dampers feature airflow-measurement probes and transmitters and measures airflow down to 100 fpm. Controllers are available with analog or BACnet MS/TP operation. Four models are available: AMD-23-TD with 3V-style blades, AMD-33-TD with fabricated airfoil blades, AMD-42-TD with extruded aluminum blades, and AMD-42V-TD with vertically oriented extruded aluminum blades.
