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 metal command handle according to OPEN - CLOSED and interval values that are written on the handle.
All of the product casing and blades are manufactured from extruded aluminium profile.
