Single-zone Opposed Blade Damper

Increase airflow control range by 30% over slide dampers

Tate’s Single-zone Opposed Blade Damper offers a dramatic airflow improvement over traditional manual slide dampers. It features a nearly infinite range of adjustment and very little airflow resistance. Easy access through the panel's surface allows for quick adjustment of the damper for accurate airflow balancing for IT hardware with fixed airflow requirements. The damper’s drop-in design allows for easy installation by decoupling the damper from the panel. This means that standard, undampered directional airflow panels can be ordered as needed, with separate opposed blade dampers purchased as necessary.
