This is an element of the natural ventilation system, designed to effectively extract the exhaust air from the room. Structurally, it is a combination of a multi-blade vertical-axis windmill (a variation of the Savonius rotor) and a centrifugal pump, and it works using wind energy, without the use of electricity.
The design of the deflector allows the device to work even at the minimum wind speed without electricity.
Characteristics
Material - stainless steel
Metal thickness - 0.45 mm
The mechanism is protected by a vacuum sleeve and a moisture-proof cuff
The rotary deflector enhances the draft in the ventilation duct and helps to normalize air circulation and solve such ventilation problems as: the occurrence of reverse draft (when air is sucked into the duct instead of going out), draft overturning (change of direction of air movement to the opposite due to temperature differences) , pulling draft in the ventilation ducts.
Advantages of a rotary deflector:
increases traction by at least 25%;
resistant to corrosion;
the rotation unit is protected from moisture using proprietary Aqua lock technology;
the device can be operated at temperatures from -50 to +50 °C;
suitable for any type of roof.
