Multi-zone Opposed Blade Damper - For DirectAire (Drop-In)

The Multi-zone Opposed Blade Damper allows for delivery of air only to where load is present, and confining airflow to where there is none. The reduction in airflow volume as a result of closing off airflow to unused sections of racks reduces energy expenditure at the CRAC unit level.

The Multi-zone Opposed Blade Damper enables individuals responsible for the physical infrastructure to deliver air where the IT user has servers and equipment installed, but restrict airflow delivery into zones where no blanking panels and no equipment is installed. Divided into three zones, (top, middle and bottom) each zone of the manual damper can be adjusted from the surface without removing the Airflow panel for fast accurate balancing to the fixed IT loads.
