Damper Actuator

Multileaf dampers with gears can only have opposed action blades.

The internal gears transfer the synchronous rotational movement from the drive arm to the individual blades.

Standard blades width 100; min. flow resistance and noise; coupling and drive possibilities for all requirements. Available in all intermediate sizes and special executions like high strength corrosion-resistant construction.

Rectangular volume control dampers are used for control of flow rate and pressure in ventilation ducts. Opposed blades in damper have aerodynamic structure that has the property of reducing the air friction. Flow rate is adjusted with actuator to OPEN - CLOSED

MATERIAL :

All of the product casing and blades are manufactured from extruded aluminium profile.

FUNCTION :

·        Multileaf dampers of Type VCD are used as an acting element in the volume flow and pressure control in air conditioning systems
