ExploreFume extraction, cartridge/bag filter, ducting, and air line selection for cutting, grinding, welding, and surface treatment lines.

Fume extraction, cartridge/bag filter, ducting, and air line selection for cutting, grinding, welding, and surface treatment lines. Dust load, operating temperature, maintenance access, and emission targets at each process point determine the product selection.
In metalworking facilities, welding fume, laser/plasma cutting, grinding, and oil mist each call for different filtration principles. Local extraction arms/benches, cartridge or bag filters, air handling equipment, and spark control are selected based on the workstation.

The filter housing, fan, ductwork, filter element, pulse-jet system and discharge/conveying equipment are not independent of one another; they are evaluated as components of the same operating point.
| Process Dew Point | Filter / dust-fume solution | Fan, ductwork and conveying equipment | Critical selection grade |
|---|---|---|---|
| Welding cells | Extraction arm/hood + cartridge/HEPA optional filter | High-vacuum air-handling equipment and balancing damper | Welding method, chromium/nickel fume, and operator position |
| Laser/plasma cutting | Cutting table zone extraction + cartridge filter | High-pressure air-handling equipment and spark pre-separation | Fine metal fume, sparks, and oily sheet metal |
| Grinding | Downdraft bench or local filter | Grinding extraction fan, cyclone separator/spark trap | Coarse hot particles and wear |
| CNC / oil mist | Mist eliminator/coalescing filter | Mist fan and drainage | Oil aerosol, fire, and return air |
| Sandblasting | Wear-resistant cartridge/baghouse filter | Cabin fan and abrasive recovery | Abrasive load and filter wear |
Compensates for the extraction arm and central duct loss.
Provides zone-based high flow/pressure.
Construction suited to abrasive particles.
Works with oil aerosol and a drained filter.
Compact solution for fine welding/cutting fume.
Heavy-duty grinding/sandblasting applications.
Captures fume at the source.
Reduces coarse hot particles.
Based on station balance.
Based on risk analysis and return-air conditions.
Exact capacity is not set by a catalog name; it is determined by process flow rate, system pressure, temperature, material/dust behavior and discharge continuity.
| technical data | Required site / process information | Impact on selection |
|---|---|---|
| Process | Welding wire/metal, cutting power, grinding load | Determines the fume characteristics. |
| Weld fume capture | Hood distance and open area | Determines the required flow rate. |
| Spark | Hot particles and oily surface | Determines pre-separation/fire prevention measures. |
| Return air | Return to indoor space and limits | Determines HEPA/monitoring requirements. |
| Operating time | Number of stations and simultaneity | Determines filter area/air handling equipment capacity. |
These are not success percentages; they are risks that must be verified on site to select the right filter, fan and auxiliary equipment.
Fume escaping past the extraction arm
Spark damage in the cartridge
Rapid clogging from oily smoke
Unbalanced central duct suction
