Overview

A motorized volume control damper sets the airflow in a duct from the building management system instead of by hand. It has a galvanized steel hat-channel frame with opposed-action extruded aluminium airfoil blades, driven by a 24 V or 230 V actuator. The product page lists modulating (0–10 V or 4–20 mA) or on/off control, a 0–10 V position feedback signal, an optional fail-safe spring return, an IP54 actuator for plant rooms and sizes from 200 × 200 mm to 1200 × 800 mm.
