Collect welding fumes from multiple workstations through shared ductwork and a central dust collector. Configure extraction arms for manual welding or dedicated hoods and enclosures for robotic welding cells.
For initial selection, send the number of simultaneously operating stations, welding process and workshop layout.
Choose extraction arms or fixed hoods to suit the welding position and workpiece. Branch ducts bring fumes from individual stations into a shared main duct.
An adjustable arm allows the hood to follow changing weld positions. Fumes are drawn through the arm and branch duct into the centralized ductwork.
A fixed hood above the welding table collects fumes from two manual welding positions. The illustrated arrangement has a 400 × 400 mm cross-section and connects to the main duct through a branch duct.
Each extraction arm or fixed hood connects to a branch duct. These branches join a main duct that carries the collected welding fumes to the central dust collector.
Robotic welding enclosures can use top extraction connected to a central duct network or an integrated cartridge dust collector mounted directly above the enclosure.
Roof-mounted arrangement
Illustration of integrated cartridge dust collectors installed above a robotic welding enclosure.
A steel-framed enclosure surrounds the robotic welding area, with an integrated cartridge dust collector mounted on top of the enclosure. Fumes are extracted from the upper part of the enclosure into the collector.
Typical welding enclosure design
The owner typically designs the enclosure around workpiece loading, operator access and production requirements.
Overhead extraction captures rising welding fumes inside the enclosure. Branch ducts carry the fumes into a shared main duct connected to the central dust collector.
Select an integrated collector to suit the required airflow, simultaneous welding load and filtration needs. The equipment below illustrates different configurations.

These are equipment examples. Explore our all-in-one dust collector range, including integrated cartridge configurations for welding fume extraction.
For multiple welding stations or robotic cells, choose the central collector according to the combined airflow, fume characteristics and workshop layout.

Illustrative arrangement of a centralized welding fume collection system.
Capture devices at the welding stations or robotic enclosures connect through branch ducts to a shared main duct. The central collector treats the combined fume-laden airflow.
Where welding fumes contain oil mist or carry hot sparks, add suitable upstream treatment to help protect the cartridge filters.
For fumes containing oil mist, a powder injection unit introduces a suitable conditioning powder into the extraction duct. Lime powder, talc or another compatible inert powder can be selected for the application to help reduce oily deposits and filter blinding.
The powder is injected upstream of the cartridge collector, mixes with the incoming fumes and forms a conditioning layer on the filters. The illustrated dimensions are layout references for this arrangement.
Hot welding sparks entering the collector can ignite accumulated material and damage the filter cartridges. An upstream spark arrestor helps reduce this risk.
Internal baffles change the airflow direction to intercept hot particles and help reduce sparks reaching the cartridge collector.
View Spark Arrestor ↗A centrifugal arrangement creates swirling airflow to separate hot particles and promote spark cooling upstream of the collector.
View Spark Arrestor ↗Spark arrestors help reduce ignition sources; they do not guarantee that all sparks are eliminated. Select the arrangement as part of the overall system fire-risk assessment.
Send us your welding process, workstation details and workshop layout so we can recommend a suitable centralized welding fume extraction arrangement.
The airflow guidance for manual welding extraction arms does not apply directly to robotic welding cells. Each robotic cell requires a separate assessment based on its enclosure, openings and extraction arrangement.
An integrated cartridge collector is a compact option for a smaller manual welding installation. A modular collector provides more flexibility for larger systems. Final selection depends on simultaneous airflow, fume loading, duct resistance and installation space.
A secondary HEPA filtration stage can be considered where the project requires it. Please tell us your discharge requirements and whether indoor air return is planned so the complete arrangement can be reviewed.
Tell us the expected future workstation count at the enquiry stage. Collector capacity, fan duty, main duct size and connection points can then be considered for the planned expansion.
Robotic enclosures and overhead hoods require their own airflow assessment. Send the enclosure dimensions, opening sizes, welding process and layout rather than selecting solely by the number of robots.
Send workshop photos, a layout sketch and the information above. We can discuss the extraction arrangement, collector configuration and equipment supply for your project.
