Characteristics of the non-powered wind cap

The term “non-powered hood” usually refers to a passive ventilation device that is designed to achieve ventilation through natural wind power without the need for an external power source or mechanical device. This type of hood is designed to harness the power of the wind and promote air circulation through clever construction. It is usually installed on the roof of a building or on a ventilation duct.

Here are some of the features and functions of unpowered air hoods:

Wind Powered: The design of a non-powered wind cap allows it to rotate through the force of natural wind. As the wind blows through the hood, it is designed to direct the wind into the interior of the hood, which drives the hood to rotate.

Ventilation: As the hood rotates, it creates a negative pressure effect that helps remove hot air, moisture or harmful gases from the building or ventilation system.

Rain Protection: Most non-powered hoods have a well-designed enclosure that effectively prevents rain from entering the building or ventilation system. This design usually includes angled blades or hoods that keep rainwater from entering directly.

Durability: Unpowered windscreens are often made of weather-resistant materials to ensure that they remain efficient in all weather conditions.

Low Maintenance: Because there are no mechanical parts in a non-powered windsock, its maintenance costs are relatively low. Its simple design requires no additional power or energy.

These features make non-powered hoods a popular ventilation solution in a number of building and industrial applications, especially in environments where heat or moisture needs to be removed.
