An excellent general purpose volume control damper. VCDs are manufactured from extruded aluminium throughout, ensuring an inherently high resistance to corrosion along with minimal weight.
Energy loss through resistance to airflow is extremely low due to a maximum free area of 86% when the damper is set fully open, and the fully protected low torque drive system means even large units can be operated from a single manual handle.
Aluminium frame and blades.
Made to order.
