Extraction and process ducting
Industrial systems usually combine several collection points into one main duct and a single fan. Getting that balance right is the difference between a system that captures at every station and one that only works at the branch closest to the fan.
- Welding and grinding fume extraction with articulated arms or fixed hoods
- Dust and swarf collection ducting with wear-resistant sections at high-load points
- Process and tank extraction in stainless where corrosion or washdown is a factor
- High-temperature runs from ovens, furnaces and dryers, specified with the appropriate clearances
- Plant-room and compressor-room ventilation to remove heat build-up
Fabricated for the plant, not for a catalogue
Industrial ducting is fabricated to suit the equipment, steelwork and clearance on site. Joints are flanged or welded as the duty requires, supports are braced against vibration, and access points are located where maintenance staff can actually reach them.
Where production cannot stop, we prefabricate as much as possible off site and work to a shutdown window for the connections that must be made live.
Working around production
We plan around shifts, forklift routes and hot-work permits, and keep the site clean of swarf and offcuts. Where a system has to remain partly operational during the upgrade, the sequence is agreed with your maintenance team before work starts.
Included in our scope
- Extraction point survey and capture assessment
- Duct sizing, fan duty and static pressure calculations
- Fabrication in galvanised, mild or stainless steel
- Flanges, bracing, supports and access doors
- Fan, hood and plant connections
- Commissioning and balancing of multiple extraction points
