The Modulating Automatic Round Damper (MARD) part number MARD6 ensures precise airflow control with its 6" diameter size. This damper utilizes a 90-second open to closed motor for efficient operation, making it compatible with various HVAC systems. The MARD6 can be used as a zone damper, with ML6161 as the replacement motor. Combined with the Static Pressure Control (SPC) for bypass applications, this damper guarantees optimal airflow distribution.
