Industrial extraction captures dust, fume, mist or vapour at the process and transports it to suitable separation or treatment equipment. Its purpose is to control the contaminant before it spreads through the workplace and becomes a building-wide ventilation problem.
Why industrial extraction matters
Airborne emissions can affect workers, equipment, product quality and housekeeping. Local capture keeps the pollutant concentrated, supports predictable filtration and limits deposits in production areas.
Main equipment types
- machine connections, hoods, extraction arms, benches and enclosures;
- circular ductwork, flexible connections and controlled gates;
- cyclones and other pre-separators for heavier material;
- bag or cartridge filters for suitable dry dust and fume;
- mist, overspray or vapour-treatment stages for their specific contaminants;
- centrifugal fans selected for airflow and total pressure;
- collection and discharge equipment for separated material;
- make-up air and air handling for building balance.
How equipment is selected
The design starts with the contaminant, source geometry, process duration and simultaneous demand. It then defines capture airflow, duct transport, filtration and fan duty. Abrasion, temperature, moisture, corrosion, combustion risk and maintenance access influence the final equipment.
A complete ALWO solution
ALWO can cover process assessment, design, component supply, installation, controls and commissioning. This system approach prevents a powerful fan from being paired with an ineffective hood or a fine filter from receiving an avoidable coarse-particle load.
Benefits of modern controls
Pressure monitoring, filter-cleaning controls, machine-linked gates and variable fan speed make performance visible and can reduce unnecessary operation. Controls are configured around transport and safety limits, not energy savings alone.
Maintenance
Routine checks cover capture points, duct leakage and deposits, filter pressure, collection discharge, fan condition, gates and alarms. Commissioning data provide the reference for determining whether performance has changed.
