ATEX fans & Ex Fans for Industrial Applications

Your ATEX Fan Expert

BarkerBille designs and manufactures ATEX fans and Ex-rated industrial fans for applications where potentially explosive atmospheres may occur due to combustible dust, gases or vapours.

Our ATEX centrifugal fans are custom-designed according to the requirements of the individual application and can be supplied with Ex marking for Categories 2 and 3 for gas and dust, for use in systems located in Zones 1, 2, 21 and 22.

With more than 50 years of experience in industrial fan engineering and extensive knowledge of ATEX requirements, we can help specify the right fan design, materials and configuration for demanding industrial applications.

Industrial ATEX fans for gas and dust

Potentially explosive atmospheres can occur in many industrial processes involving combustible dust, gases or vapours. Fans used in these applications must be designed to avoid own internal ignition sources and comply with the relevant requirements for the specified ATEX category and operating conditions.

BarkerBille supplies ATEX industrial fans for both dust and gas applications. Each fan is designed based on the requirements of the specific project, including the ATEX classification as well as airflow, pressure, temperature, media, materials and installation conditions.

Our ATEX fans can be supplied for:

• Category 2 and Category 3
• Gas and dust applications
• Zones 1 and 2 for gas
• Zones 21 and 22 for dust
• Different materials and surface treatments
• Application-specific centrifugal fan designs

Custom-designed ATEX Centrifugal Fans

ATEX compliance is only one part of selecting the right industrial fan. The fan must also deliver the required performance reliably and efficiently under the actual process conditions.

BarkerBille ATEX centrifugal fans are therefore designed specifically for each application. Depending on the project, we can adapt the fan according to requirements for airflow, static pressure, operating temperature, materials, drive configuration, efficiency and the characteristics of the media being handled.

Our extensive range of centrifugal fan designs gives our engineers the flexibility to select and configure a solution that combines the required Ex protection with efficient and reliable fan operation. We ensure:

• Compliance with the relevant requirements at any time
• Continuous product development according to requirements
• Highest level of protection
• Access to the most recent knowledge

ATEX fans for different industrial applications

ATEX fans are required in a wide range of industrial processes where combustible dust, gases or vapours can create a potentially explosive atmosphere. The exact requirements depend on the process, media and ATEX zone classification.

BarkerBille designs and manufactures custom ATEX centrifugal fans for both dust and gas applications. Below are some typical examples.

ATEX Fans for Extraction Systems

Dust extraction and material handling systems are common applications for ATEX fans, particularly when handling combustible dust from materials such as wood, grain, paper or other production processes.

BarkerBille supplies ATEX centrifugal fans for extraction systems as well as material transport fans designed to handle dust and solid material. The fan design is adapted to the material being handled and the requirements of the individual extraction system.

Ex Fans for Spray Drying

Spray drying processes in the food and dairy industries can require Ex-rated fans due to the presence of combustible powders in the process.

BarkerBille has more than 50 years of experience supplying centrifugal fans for spray drying plants. Depending on the application, fans can be supplied with Ex marking as well as special features such as stainless-steel construction, sanitary design and preparation for CIP cleaning.

Ex Gas Fans for Pyrolysis

Industrial processes involving potentially explosive gases require fans specifically designed for the gas composition, temperature and operating conditions.

BarkerBille supplies custom-designed Ex gas fans for demanding process applications, including pyrolysis. These can include gas extraction and gas recirculation fans designed to handle both high temperatures and challenging process gases.
