These fans are essential for compliance with building regulations and achieving optimum indoor air quality.

Types of Commercial Extractor Fans

There are several types of commercial extractor fans available in the market, each designed to cater to different requirements and installation scenarios.

Inline Commercial Extractor Fan

An inline commercial extractor fan is typically installed within the ductwork of a ventilation system. It is placed in the airflow path and can be used in conjunction with a ducting network to extract air directly from specific areas. This type of fan is commonly used in larger commercial spaces where it is necessary to extract air over long distances.

Roof-Mounted Commercial Extractor Fan

As the name suggests, a roof-mounted commercial extractor fan is installed on the roof of the building. It is designed to provide ventilation for large industrial spaces, such as warehouses or factories. These fans are ideal for situations where there is limited wall space or when it is not feasible to install the fan inside the building.

Wall-Mounted Commercial Extractor Fan

Wall-mounted commercial extractor fans are installed on an external wall of the building. They are commonly used in kitchens, restaurants, or smaller commercial spaces, where the air extraction needs are lower. This type of fan is relatively easy to install and provides efficient ventilation by extracting air directly from the area.

Ceiling-Mounted Commercial Extractor Fan

Ceiling-mounted commercial extractor fans are installed directly into the ceiling of the commercial space. They are designed to be discrete and blend seamlessly with the ceiling, making them a popular choice for retail environments or office spaces. Ceiling-mounted fans are often equipped with built-in lighting, providing a dual functionality of ventilation and illumination.

Ductless Commercial Extractor Fan

A ductless commercial extractor fan, also known as a recirculating extractor fan, is a compact and portable option that does not require ductwork for installation. Instead, it recirculates the air within the space through a filter system. This type of fan is commonly used in smaller commercial spaces or areas where it is not practical to install a ducted ventilation system.

Features of a Commercial Extractor Fan

Commercial extractor fans come equipped with various features that enhance their functionality and performance. These features are specifically designed to meet the demands of commercial environments and ensure optimal air quality.

Powerful Motor
