Rotating deflectors are devices where part of the structure is moved by wind energy. Instead of static models, they create additional rarefaction even in low winds, which significantly increases the efficiency of ventilation in difficult climatic conditions.
The principle of operation is based on the conversion of horizontal air flow into rotational motion of the rotor with blades. The rotation creates centrifugal forces that increase the draught and pull air out of the ventilation duct.
Turbodeflectors are the most popular type of rotating deflectors. They are spherical or cylindrical designs with blades rotating around a vertical axis. The wind sets the rotor in motion, and centrifugal forces effectively remove air from the system.
Advantages of turbodeflectors:
-
High efficiency even in low wind conditions;
-
Independence from wind direction;
-
Protection from precipitation;
-
No need for power supply;
-
Silent operation if properly balanced.
Modern models are equipped with ball bearings, which reduces friction and increases sensitivity to weak air currents.
Materials of deflector production:
-
Stainless steel
-
Advantages: high corrosion resistance, durability, heat resistance.
-
Usage: aggressive environments (chemical industry, high humidity).
-
Aluminium
-
Advantages: lightweight, corrosion-resistant, good heat dissipation.
-
Usage: ventilation systems where weight and resistance to external influences are important.
-
Galvanised steel
The choice of material depends on the operating conditions - humidity, chemical aggressiveness, durability and appearance requirements. The right choice ensures reliable and efficient operation of the ventilation system.
