The T3SQ-4 works in both heating and cooling applications. The curvature of the backpan works with the formed edges of the face panel to deliver a tight horizontal air pattern without excessive noise or pressure drop over the full range of operation. As the volume of air is decreased by the control disc, the velocity of air is increased, thus maintaining the longest throw and best entrainment. This ensures superior performance at all damper positions.
• Adjustment of the green tab offset creates a temperature deadband for heating and cooling setpoints
• Adjustment of minimum airflow is achieved by rotating the grey minimum airflow adjustment ring
• The face panel and backpan are constructed from 18-gauge steel. The formed outer edge also assures a straight and level surface.
