Multi-zone Opposed Blade Damper - For DirectAire AL & DirectPerf32 (Field-Mounted)

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.

  • Adjustable from top without removing raised floor panel
  • Quarter turn adjustment for 0-100% range of damper
  • Field-mounted using self-tapping screws
  • Airflow panel-mounted to minimize air leakage between panel and damper
  • Supports both 24" and 60cm raised floor systems
  • Designed for use with 32% DirectPerf, DirectAire® Al
  • Made from anodized extruded aluminum
  • Damper Weight: 3.8 lbs. (1.7 kg)
  • Dimensions: 22.5" length x 22.5" width x 1.75" depth (57.15 cm length x 57.15 cm width x 4.45 cm depth

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.

*Cooling capacities were calculated using the following formula:(CFM x Capture Index %) / 126(CFM needed to cool 1kW @ 25ºF ?T)= kW per rack.

INSTALLATION

The DirectAire Al panels utilize the inner 4 holes to mount the Opposed Blade Damper. Please ensure the airflow panel and OBD is oriented correctly in respect to the server rack. The vanes of the OBD should be in the same orientation as the slots of the panel.

The 32% DirectPerf panels utilize the outer 4 holes to mount the Opposed Blade Damper. Please ensure the airflow panel and OBD is oriented correctly in respect to the server rack. The vanes of the OBD should be in the same orientation as the slots and louvers of the panel.
