Machining & Fabrication
Welding fume, grinding and cutting dust extraction with cartridge collectors and central duct networks.
Working condition
Recommended configuration
Each row shows the process stage, the machine we normally select and the point that decides whether it performs on site.
| Process stage | Recommended equipment | Selection point |
|---|---|---|
| Welding fume | Cartridge dust collector with central duct networkGP-LT Series | Hood design per welding position, duct balancing to keep equal capture at each arm. |
| Grinding and cutting dust | Baghouse or cartridge collectorGP-LCM / GP-PPC Series | Spark arrestor upstream for dry grinding, media chosen for metal dust. |
| Oil mist | Mist collector with pre-separationGP-LT Series | Pre-separator and drainable media to avoid blinding by oil. |
| Chip and swarf handling | Drag chain or screw conveyorGP-MS / GP-FU Series | Enclosed conveying from machine pits to the chip bin. |
| Extraction energy | VFD control on extraction fanGP-VFD Series | Speed follows the number of working stations through damper or pressure feedback. |
Energy
Workplace exposure limits for welding fume and metal dust are defined by national occupational health regulation. Capture effectiveness depends on hood position and cross draft in the workshop.
