Cartridge, baghouse and wet dust collection systems, configured around your dust characteristics, process and installation conditions.
Choose downflow or vertical cartridge collectors, baghouse systems or wet collection. Protection options include explosion venting, isolation, static control and suitable electrical components, selected for the application.
Protection equipment and component certifications are specified for each project; they do not imply ATEX certification of the complete system.

Our explosion-protected dust collectors are based on conventional cartridge, baghouse or wet collector designs, with application-specific protection equipment and the necessary structural, electrical and control provisions. The collection principle remains the same; the protection package is selected around the dust and the installation.
Safety requirements vary by country and region. Not every application requires every protection device shown on this page. The appropriate combination is selected to meet applicable local regulations and project requirements, taking account of the dust hazards and installation conditions.
Adding an explosion-proof motor or an antistatic filter alone does not make an ordinary collector a complete explosion-protected system.
Choose compact downflow units or vertical cartridge systems to suit the airflow, dust loading and available installation space. The photos below show equipment configurations and installation details.

Round-bag and flat-bag designs offer alternative filter layouts. Filter media, cleaning arrangement and discharge equipment are selected for the dust and operating conditions.

Wet collection can be an option for suitable aluminum and other combustible metal processes. Dust–water compatibility, hydrogen management and sludge handling are part of the configuration.
Click to enlargeCone-hopper discharge provides a defined outlet for settled sludge. Discharge frequency and downstream collection are selected around the solids load and material properties.
Click to enlargeA chain-driven scraper with flights removes settled sludge from the collection tank. The aluminum products visible in this installation show the actual application setting.
Available configurations include hydrogen vent valves, water-level monitoring and appropriate operating interlocks. Reactive metal fines can release hydrogen in contact with water: vent arrangements must address operation and shutdown. Regular sludge removal and a suitable waste-handling plan remain necessary.
We tailor the wet dust collection system to your specific alloy, process residues and compatibility with water, with coordinated water-level control, hydrogen venting and sludge removal.
These are available configuration options, not a checklist of devices that must all be installed. Selection follows applicable local regulations, project requirements and the dust hazard assessment. The agreed equipment list and drawings define the supplied scope.
Ignition prevention addresses sources such as static discharge and incoming sparks. Explosion venting relieves explosion pressure into a planned discharge area. Explosion isolation limits propagation through connected equipment. Flameless venting still requires suitable clearances and application-specific selection.
Ordinary rotary discharge valves and HEPA filters should not be treated as explosion isolation devices. Indoor installation and return air require a specific system design.
Send the information you already have. We can identify the missing inputs needed to define the collector and protection scope; there is no universal explosion-protection package based on airflow alone.
| Selection input | What to provide |
|---|---|
| Dust & process | Material or alloy, process description, particle size, moisture, temperature, and any oil or other contaminants. |
| Dust test data | Available Kst, Pmax and ignition-sensitivity data for a representative sample, plus the site dust hazard assessment where available. |
| Air duty | Required airflow, dust loading, capture points, operating hours and available pressure or duct layout. |
| Installation | Indoor or outdoor location, nearby occupied areas, vent discharge space, duct routing and air discharge or return-air requirements. |
| Utilities & project requirements | Power supply, compressed air, water for wet systems, hazardous-area classification and required component documentation. |
Kst describes dust explosion severity; Pmax is maximum explosion pressure in a standard test. They are dust properties, not a universal collector rating. Final design also depends on enclosure strength, venting and the installation.
Private-label supply, custom colors and project-specific arrangements are available. Component certifications can be specified where applicable. ATEX/IECEx certification of individual components does not certify the complete collector or installed system; whole-system ATEX certification is not included in our supply offer.
Practical answers about the base collector and its protection configuration.
The term is commonly used for a dust collector configured for combustible dust. Our designs use conventional collector platforms with selected explosion protection equipment and the necessary structural, electrical and control provisions. The term does not mean that an explosion is impossible.
Those pages explain standard base designs and working principles. Explosion protection is specified separately; the standard equipment shown should not be assumed to include it.
No. It forms part of static control when correctly bonded and grounded. Other ignition sources, explosion pressure relief and propagation through ductwork must also be addressed as required by the application.
It can be an option for suitable aluminum processes, subject to the actual alloy, residues and water compatibility. Water-level control, hydrogen venting and sludge removal are important parts of the system.
Sometimes, but suitability depends on the existing enclosure, filter system, ductwork, space and controls. Send drawings and photographs so the required changes can be reviewed before a retrofit scope is proposed.
Send your dust material, required airflow, installation photos and available test data. We will discuss the base collector, protection options and supply scope.
