wind_driven_roof_ventilatorWind driven roof ventilation system is a mechanical ventilation system that operates using wind extractors, which, as the name suggests, are powered by the wind outside and the differential effects of external and internal temperatures under  the edification’s roof.

Wind turbine vent are widely used in industries,houses and buildings. Is one of the best solutions for a non-electric alternative to ventilation.

The Eolic Wind Extractor is an innovative exhaust ventilation system that provides a constant renewal of air 24 hours a day, increasing productivity due to the improvement of environmental conditions on work areas, at the lowest cost.

This wind extractors use the energy generated by the wind to ventilate different enclosures. They have very good  cost – benefit relation, because with a relatively low initial investment and no energy consumption, combined with the no noise generation, offers an ecological solution to the problems of overcrowding in poorly ventilated areas, making well-being for the people who live there or develop their tasks, removing odors and heat properly.

Operation of an Wind driven Roof Ventilation System

The Wind Turbine Attic Vents operates as follows:

The wind extractor sucks out (output) the hot air accumulated under the building cover, which is naturally compensated by fresh air through windows located strategically in the lower strata of the site, this process, technically directed, will generate a level of air circulation within the enclosure to ensure proper ventilation.  They do it with a series of specially shaped vanes that catch the wind and provide rotary motion. This pulls hot, humid air from the attic. Turbine vents provide a low-cost ventilation alternative in areas where wind speeds of at least 5 mph are typical.

This is the way in which an appropriate ventilation system works, allowing you to get rid of heat, moisture, fumes, pollution and odors accumulated inside the building. Therefore, and for not generating operating costs, Wind Ventilation System is one of the best and most economical option in ventilation.

Wind Extractor Physical Characteristics:

extractor eolico-Manufactured entirely in aluminum.
-Mounted on pre-lubricated and sealed bearings.
-Extract air by wind action and differences in environmental temperatures inside and outside.
-Do not allow water entry.
-Easy installation: great adaptability to different types of roofs due to its light weight.
-Resistant to weathering and the aggression of gases, fumes and vapors.

It should be taken into account when using wind turbine extractors, that the extraction capacity of any system of ventilation is a function of the balance between incoming and outgoing flow of air to the building.  That is, the extraction capacity of the system must be able to be sufficiently compensated with  a sufficient income of air  to the building by providing natural access to the same, such as windows, skylights, doors, block drafts, etc.

IAlso, if you decide to add a turbine vents to your roof, be sure to buy ones that are aluminum. These will not rust. In addition, pay attention to the maximum roof pitch that will work with the turbines. The turbines are adjustable so that the spinning part is level even though the roof is slanted. Not all turbines will fit all roof pitches.
