Industrial welding fume extractionTREAL designs and manufactures welding fume extraction systems that capture fumes at the emission point, filter them and return clean air to the plant, for manual or robotic welding.
The fume generated at the welding arc contains fine metal particles that spread through the plant and can be inhaled by the welder. The most effective way to control this emission is to capture the fume as close to the source as possible, before it disperses.
A welding fume extraction system has three stages: capture (extraction arm, table, hood or extraction torch), filtration (cartridge filter) and ventilation (a fan sized for the airflow and pressure drop of the duct network). Each choice depends on the process, the number of stations and the plant layout.
TREAL surveys the site, sizes and manufactures the system, taking into account the applicable occupational safety requirements in Brazil, such as NR-09, NR-12 and NR-15.
From a single station to a robotic cell, these are the TREAL products most used in welding fume extraction.
Self-supporting aluminum arm with precise positioning for capture directly at the weld zone.
Compact unit to capture welding fumes without fixed ductwork. Pairs with the TR-ARM arm.
Dual bottom and front capture for metal fumes and grinding particles at the workstation.
Manual MIG/MAG torch with integrated extraction and ergonomics to reduce operator exposure.
Unit with two filter elements and compressed-air pulse cleaning for extraction torches and continuous extraction.
Perimeter capture for robotic welding and defined emission areas, in 18 sizes.
Filters from 2 to 16 cartridges for welding, from compact stations to large plants, with Pulse-Jet cleaning.
In practice, both terms refer to the same goal: removing the fume generated by welding. An exhaust fan usually means the fan that moves the air; the complete system also includes the capture point (arm, table, hood or torch) and the filter that retains the particles.
If the air is returned to the plant, it must be filtered. An exhaust fan without a filter only moves the fume somewhere else. In welding, a cartridge filter retains the fine metal particles.
For manual welding, extraction arms, tables and extraction torches capture right at the welder. In robotic cells, modular hoods such as the TR-FLEX capture the fume from the defined area. The final choice depends on the process and layout.
Sizing considers the number of stations, the type and current of welding, the distance to the filter and the duct network. TREAL surveys the site and proposes the system; to start, just talk to our engineering team.
Yes. TREAL handles site survey, design, manufacturing, installation and preventive maintenance, as well as replacement filter cartridges.
Tell us the process, the number of stations and the layout. Our engineers will recommend the system and send a proposal.
