Digital Single Duct Terminal. Single Duct terminals are the fundamental building blocks for Variable Air Volume (VAV) systems. Their primary function is to regulate airflow to a zone, in response to zone temperature requirements. The Titus ESV is unique as it incorporates many design features that increase performance, decrease service and installation costs, and offer increased value, over and above this basic function.

The Titus AG-85 is a duct mounted butterfly damper used in round duct applications. Continuously adjustable from fully open to fully closed. Friction pivots hold the heavy gauge blades at the desired setting. Damper blades open upward into air stream. Not recommended for use with flexible duct. Adjustable at screwdriver operator slot
