Cowl wind powered extractor fan

A cowl wind powered extractor fan is a system that utilizes wind power to move air. Without the need for electricity, this fan ensures effective air circulation. The hood-shaped top, known as the cowl, captures the wind and helps draw air out of the space. These wind powered extractor fans are typically installed on roofs and contribute to improving air quality in various types of buildings.

How does a cowl wind powered extractor fan work?

This fan operates by the wind blowing over the hood-shaped top, causing the blades inside to rotate. This rotational movement creates a force that pulls air outward. Depending on the wind speed, the fan can increase air exchange without requiring external energy sources.

What different models are available?

There are three different cowl wind powered extractor fans in the range, each with its own characteristics:

150mm Stainless Steel including mounting plate (65 m³/h): A smaller version, suitable for compact spaces or situations where limited ventilation capacity is sufficient. Made of stainless steel, it offers long-lasting performance.
200mm Stainless Steel including mounting plate (115 m³/h): A medium-sized option, ideal for larger rooms. This version provides more air displacement, also made of stainless steel for added durability.
250mm including mounting plate (180 m³/h): The largest variant, designed for large spaces or intensive applications. This fan offers maximum air displacement and is robust enough to perform in harsh conditions.

What are the differences between these models?

Diameter and Capacity: Each variant differs in diameter and the amount of air they can move. The 150mm version is the smallest and moves 65 m³ of air per hour, the 200mm version moves 115 m³/h, and the largest 250mm version can move 180 m³/h. Larger fans are better suited for larger spaces.
Application: The smaller version fits in smaller spaces, while the larger variants are better suited for larger areas or industrial environments.
Material: All fans are made of stainless steel, ensuring long-lasting performance and resistance to weather conditions.
