• Frame is made from High quality extruded aluminum with flanged edge 30 mm and connected by screw nails.
• Blades are made from High quality extruded aluminum with width 100 mm and 120mm connected by plastic gears to transfer motion.
• Handle locking quadrant designed to show exact position of blades (degree of deflection angle).
• Rubber seal fixed on the edge of the blades to minimize leakage of air.
• Volume dampers designed with flanged edges for connecting duct and without flange for duct inside are available as option.
• Volume control dampers specifically designed to provide positive control within ducted air system.
• Volume control damper designed to use in heating, ventilation and air condition system.
• Volume control dampers can be designed with special linkage to fix electric motor.
• Dampers sizes start from 120 mm x 120 mm and maximum size 1000 mm x 1000 mm in single section and non-standard sizes are available.

We have different sizes of blades (three sizes) and different sizes of the rubber seal (five sizes) This makes us distinguished in the sales market by maintaining the required amount of air in the designs of the project. As the other companies compensate for the different sizes of fixed angles, which reduces the amount of or, and therefore lack of commitment to the design.
