Industrial extraction must be adapted to the process because wood dust, welding fume, paint overspray, oil mist and pharmaceutical powder do not behave in the same way. A customised installation connects the right capture method, transport velocity, treatment stages and controls to the actual production layout.
Why customisation matters
Two factories with similar floor area can have completely different emission sources, simultaneous machine demand and maintenance constraints. Selecting equipment only by building size or nominal fan airflow risks weak capture, rapid filter loading or unnecessary energy use.
Different industries, different control strategies
- woodworking: machine capture, transport velocity, cyclonic pre-separation and high-load filtration;
- metalworking: fume, abrasive particles, sparks, oil mist and process-specific separation;
- painting and finishing: overspray capture, filtered make-up air, pressure balance and compound-specific vapour treatment where required;
- food and pharmaceutical production: close containment, cleanability and cross-contamination control;
- bulk-material handling: transfer-point capture, dust filtration and coordinated material discharge.
Project stages
- survey machines, materials, operating states and the existing building airflow;
- identify contaminants, temperatures and safety conditions;
- design hoods and calculate branch airflow;
- size ductwork, filtration, fans and make-up air;
- coordinate controls and installation with production;
- commission, balance and record baseline measurements;
- train operators and establish maintenance criteria.
Benefits of an engineered solution
A correctly configured system uses airflow where production needs it, protects final filters through suitable pre-separation, makes collected material practical to remove and allows maintenance without unnecessary downtime. It is also easier to adapt when machines or operating schedules change because the original capacity and design basis are documented.
Custom does not mean unnecessarily complex
The simplest system that meets the process requirement is generally preferable. Custom engineering means selecting only the components and treatment stages that add technical value, not adding technology for its own sake.
