Regulation dampers with low pressure drops and low self-generated noise
They can be used in air conditioning, ventilation and air handling units
Patented galvanised steel regulation dampers, pitch 100mm with nylon rotation pins. They can be place in the regulation and in the balance of air flow and pressure, in the air conditioning and ventilation systems and treatments centres. This innovative damper, thanks to a special shaping of the frame and stopper of the fins, it guarantees considerable advantages:
1) Completely free air passage
2) Strong reduction of pressure drop
3) Strong reduction of self-generated noise. These shrewdness, combined with the particular plastic elements inserted at the ends of the fins, also guarantee a limited leakage of the air with closed damper. An innovative universal metal plate allows the application of all manual or motorized controls. The opening and closing of the fins takes place by a manual control placed on one side of the damper connected to an external lever system. The same movement can be achieved through a wide range of servomotors that allow a more precise adjustment of the passage of air in the duct.

For damper with length (L) > 1250 mm ≤ 2500 mm will be placing a breaker with thickness 30mm in central position.
For damper with length (L) > 2500mm ≤ 3000 mm will be placing two breakers with thickness 30mm with same distance. Dampers can have these maximum dimensions:
