ATEX roof fans

Looking for a safe solution for extracting air from a hazardous area? An ATEX roof fan, also known as an ATEX roof exhaust fan, is often an effective choice. These fans are specifically designed for roof mounting on buildings or industrial installations, providing safe and efficient extraction of air, vapours or gases to the outside.

ATEX roof fans are suitable for environments where flammable gases, vapours or combustible dust may be present and are designed to meet the applicable ATEX requirements. This makes them suitable for a wide range of industrial applications where safe and reliable air extraction is essential.

The products shown below represent our standard range and are only a selection of the solutions we offer. Every application is different, which is why we always select and configure the fan to match your installation, required airflow, pressure, mounting arrangement and ATEX classification. This ensures you receive a solution that is fully suited to your specific requirements.

Whether you need a standard explosion-proof roof fan or a fully customised ATEX roof exhaust fan, our specialists are happy to help you find the right solution.

Why choose an ATEX roof fan?

A roof fan is installed directly on the roof of a building or industrial installation. This allows contaminated or potentially explosive air to be discharged directly outside, without the need for an extensive internal duct system. This makes roof fans an efficient solution for many industrial ventilation applications.

When the fan is used in a hazardous area, an ATEX-compliant configuration is required. An ATEX roof fan is designed to minimise the risk of ignition and operate safely within the applicable ATEX zone.

Applications of ATEX roof fans

ATEX roof fans are commonly used for:

  • Process air extraction
  • Ventilation of storage areas
  • Chemical installations
  • Paint and coating facilities
  • Production areas
  • Tank storage
  • Pharmaceutical facilities
  • Food processing
  • Laboratories
  • Extraction of vapours and solvents

 

By installing the fan on the roof, extracted air can be efficiently discharged outside while valuable floor space inside the building remains available.

Axial or centrifugal roof fan?

Not every installation requires the same fan technology. That’s why ATEX roof fans are available with both axial and centrifugal fan technology.

An ATEX axial fan is particularly suitable when large volumes of air need to be moved at relatively low pressure. An ATEX centrifugal fan, on the other hand, is a better choice when higher pressure is required to overcome resistance from ductwork, filters or other system components.

The most suitable configuration depends on factors such as the required airflow, static pressure and installation. We therefore always select the fan based on your specific application.

Suitable for different ATEX zones

The right roof fan depends on the conditions in which it will operate. Important factors include the hazardous area classification, the type of gas or dust present and the required temperature class.

Our specialists can help you determine the most suitable configuration for your application.

Would you like to learn more about the different classifications? Read our article about ATEX zones.

Always tailored to your installation

No two roof installations are exactly alike. That’s why we supply ATEX roof fans in different configurations, capacities and materials.

Depending on the application, fans can be supplied with different motors, protective covers, non-return dampers, roof curbs and other accessories. Customised solutions are also available when required by the installation.

This allows us to supply a fan that matches your process, installation and ATEX classification.

Safety and reliability

Safety is always the starting point when working in hazardous areas. That’s why we look beyond the required airflow when selecting an ATEX roof fan.

We consider factors such as:

  • Hazardous area classification
  • Gas or dust group
  • Temperature class
  • Required airflow
  • Static pressure
  • Mounting arrangement
  • Ambient conditions

 

This ensures the fan is not only technically suitable, but also safe for the intended application.

Maintenance of an ATEX roof fan

An ATEX roof fan also requires regular maintenance. Periodic inspection helps maintain safe operation and contributes to a long service life.

Important inspection points include:

  • Impeller
  • Bearings
  • Fasteners
  • Electrical connections
  • Dirt and contamination
  • Vibrations

For major repairs or modifications, we always recommend contacting us beforehand. This helps ensure that the explosion-proof characteristics of the fan are maintained.

For more information, read our articles about ATEX fan maintenance and EN 14986.

Frequently asked questions about ATEX roof fans

When should I choose an ATEX roof fan?

An ATEX roof fan is suitable when air, vapours or gases need to be safely extracted through the roof from a hazardous area.

An axial fan is mainly suitable for moving large air volumes at relatively low pressure. A centrifugal fan is better suited to applications requiring higher pressure to overcome resistance from ductwork, filters or other components.

They are commonly used in chemical plants, storage facilities, production areas, paint and coating facilities, laboratories and other industrial environments where explosive atmospheres may occur.

Yes. In addition to our standard range, we supply customised solutions tailored to the required airflow, installation and ATEX classification.

This depends on the specific configuration. The suitable fan depends on factors such as the ATEX zone, gas or dust group and temperature class.

Yes. Regular inspection and maintenance are important for safe operation and a long service life.

Your industrial fan specialist since 1999

Since 1999, we have been helping companies find the right industrial fan for their application. Over the years, we have sold and delivered more than 175,000 fans to customers in more than 71 countries. With a range of over 30,000 products, we offer a wide variety of ventilation solutions. And because no installation or application is the same, we are also happy to help when a standard solution does not meet your requirements.

Custom solutions are standard for us too. Whether you need specific dimensions, materials, performance or other specifications, we can work with you to find a suitable solution when an existing fan does not meet your requirements. Thanks to our technical expertise and years of experience in industrial ventilation, we can quickly switch between standard and custom solutions. This allows us to help installers, machine builders, OEMs and end users worldwide find an industrial fan that fits their application.
