ATEX is the name given to two European Union directives that aim to protect employees from explosion risk in areas with an explosive atmosphere. An explosive atmosphere can be caused by flammable gases, mists, vapours or combustible dusts. If these elements are present in sufficient quantities, combined with air and an ignition source, an explosion can occur. For industrial processes that generate these hazardous conditions, specialized ATEX filter units and dust collectors are not just beneficial, they are mandatory.
Our ATEX filter systems are engineered to address the unique challenges presented by explosive dusts. We provide solutions for both low and high vacuum applications, with air volumes ranging up to 45,000m³/h, suitable for ATEX-Zones 21/22 and 21/21. These systems are equipped with automatic compressed air cleaning, ensuring continuous and efficient operation while maintaining safety.
Our commitment to innovation means our ATEX filter units come with features designed for optimal performance and safety. We integrate advanced elements to mitigate risks associated with explosive dusts, providing peace of mind for our customers. When you choose Gram Clean Air, you're investing in a solution built on expertise and cutting-edge technology.
A cornerstone of our ATEX filter units is the automatic compressed air cleaning system. This feature is crucial for maintaining filter efficiency and extending the lifespan of the filter media, especially in challenging environments with explosive dusts. The continuous cleaning process prevents the accumulation of dust on the filter surfaces, which could otherwise lead to reduced airflow and increased explosion risk. This automation also minimizes the need for manual intervention, enhancing safety for your operational team.
Our ATEX filter units and dust collectors are meticulously designed and certified for use in ATEX-Zones 21/22 and 21/21. These classifications denote areas where combustible dust is likely to be present in the air as a cloud or as a layer. Understanding and adhering to these zone requirements is paramount for safety. Our systems incorporate specific design elements, materials, and safety measures to prevent ignition sources and contain potential explosions, fully complying with the stringent demands of these hazardous environments.
We ensure that every component, from the filter housing to electrical connections, meets the necessary ATEX standards, providing a complete and compliant solution for your operation. Our dedication to safety is reflected in every aspect of our product development.
Whether you require extraction for a small workshop or a large-scale industrial facility, our ATEX filter units are designed to meet a wide array of demands. We offer systems capable of handling air volumes from 500m³/h up to 45,000m³/h, making them highly versatile. This scalability ensures that regardless of the size or complexity of your application, Gram Clean Air can provide an effective and safe ATEX dust collector solution. Our solutions include options for re-cleanable and non-re-cleanable filters, tailored to your specific process requirements.
In 2024, our innovations in filter unit technology led to solutions offering up to 55% less energy consumption, reflecting our commitment to both environmental responsibility and operational efficiency.
Beyond our core ATEX filter units, we offer a comprehensive range of integrated solutions and accessories that enhance the safety and effectiveness of your dust extraction system. These components are designed to work seamlessly together, forming a complete and compliant solution for handling explosive dusts.
For applications with large dust amounts, our pre-separators are an invaluable addition to any ATEX dust collector system. These devices are strategically placed before the main filter unit to capture larger particles and reducing dust volumes before they reach the filters, significantly reducing the filter load and ensuring a longer lifespan on filters. This proactive approach to safety is in industries where processes generate large amounts of dust.
To provide targeted capture of explosive dusts and fumes at the source, we offer a range of point extraction arms that can be integrated with our ATEX filter units. These arms are available in diameters between ø50mm and ø200mm and lengths between 1m and 9m. They are ideal for welding fumes, steam, and gases, as well as for processes generating explosive dusts. Our extraction arms ensure that hazardous substances are captured before they can disperse into the wider environment, providing immediate protection to workers. We also provide telescopic arms for small welding booths and premises with low ceilings, offering flexible and effective localized extraction.
| Extraction Arm Series | Diameters | Lengths |
|---|---|---|
| Standard Arms | ø50mm - ø200mm | 1m - 9m |
| Telescopic Arms | Various | Compact designs |

ATEX refers to European directives concerned with controlling explosive atmospheres. For industrial dust collection, it means that if your process generates combustible dust, your dust collector and filter units must be specifically designed and certified to prevent explosions. This includes features like explosion relief, robust construction, and prevention of ignition sources to safely handle potentially explosive dusts.
No, not all dust collectors are suitable for ATEX environments. Standard dust collectors are not designed to handle potentially explosive dusts and using them in such conditions can be extremely dangerous. ATEX filter units and dust collectors are specially constructed with features like explosion vents, flame arrestors, and antistatic filter media to comply with ATEX directives and ensure safety in hazardous zones.
Our ATEX filter units ensure safety through several integrated features. They are designed for specific ATEX-Zones (e.g., 21/22 and 21/21), include automatic compressed air cleaning to prevent dust buildup, and can be equipped with pre-separators. All our systems are manufactured in accordance with the EU Machine Directive and are CE-marked, guaranteeing compliance with stringent safety standards for handling explosive dusts.
Gram Clean Air offers a wide range of ATEX filter units capable of handling air volumes from 500m³/h to an impressive 45,000m³/h. This broad capability ensures that we can provide an effective and safely scaled ATEX dust collector solution for almost any industrial application, regardless of its size or the intensity of dust generation.
Determining the right ATEX dust collector depends on several factors, including the type of dust, its explosive properties, the volume of air to be filtered, and the specific ATEX zone classification of your area. Our technical team at Gram Clean Air can assist you through this process. We offer expert consultation and utilize tools like our Kanalberegner (Duct Calculator) to help design the optimal ATEX filter unit solution for your unique requirements.
