Industrial filter systems do not work the same way in every sector. High temperatures and sparks in a foundry, combustible shavings in a woodworking shop or hygiene requirements in a food plant change the entire design, from the filter type to the duct route. On this page you will find the application areas of industrial filter systems, organized by the sectors for which FLTS engineers projects, together with solutions prepared for the specific conditions of each sector.

Filter and Fan Selection by Sector
Industrial filter selection starts with the type of dust. Two lines with the same airflow, one carrying wood shavings and the other welding fumes, require different filter systems. The table summarizes which dust collection systems stand out in the sectors we work with most often.
| Sector | Typical dust and fumes | Recommended system |
|---|---|---|
| Foundry | Metal oxide fumes, silica-bearing sand dust, sparks | Foundry dust collection systems |
| Food and pharmaceuticals | Flour, sugar, starch, active ingredient dust | Food and pharmaceutical dust collection |
| Cement, lime and aggregates | Abrasive fine dust, high dust load | Jet pulse bag filter |
| Wood and furniture | Wood shavings, sanding dust, combustible dust | Cyclone pre-separation stage and bag filter |
| Welding and metalworking | Welding fumes, grinding dust | Jet pulse cartridge filter |
| Sandblasting | Abrasive media and mill scale dust | Sandblasting dust filter |
| Painting and coating | Paint particles, solvent vapors | Wet paint booth with water curtain |
| Silos, feed and grain | Pneumatic conveying and filling dust | Silo-top jet filter |
| Chemicals and plastics | Combustible fine dust, vapors | Antistatic cartridge filter and ATEX explosion-proof fan |
| Machining (CNC) | Oil and emulsion mist | Industrial oil mist filter |
| Boilers and combustion plants | Hot flue gas and ash | Industrial chimney filter and gas cooling unit |
| Processes with wet and sticky dust | Moist, sticky or spark-laden particles | Water filter |
Whichever system is selected, the air-moving equipment is chosen from our industrial fans range according to the airflow and pressure drop of the line.
Information to Prepare If Your Sector Is Not Listed
The table shows common cases. For a different process, it is enough to start with the following information:
- The machines that generate dust or fumes and their number.
- The type of dust and, if possible, a sample.
- Air temperature, humidity and combustibility information.
- The simultaneous operating ratio of the machines and the shift pattern.
- Where the filter will be installed: indoors, outdoors or on the roof.
- What will happen to the collected dust: will it be disposed of as waste or returned to the process?
Once you fill in the quote request form with this information, a site survey is scheduled.
