What the fans do here
Tyre plants generate carbon black dust in mixing, rubber fume in curing, and heat everywhere. Bag filter fans on the carbon black handling system, fume exhaust on the curing presses, and heavy ventilation across the plant are the main duties.
Applications in this industry
| Application | What it does | Type usually selected |
|---|---|---|
| Dust Collector Fan | The fan behind a bag filter, cyclone or multiclone on a dust extraction system. Placed on the clean side where possible so the blade can be chosen for efficiency. | Backward inclined and radial tipped |
| Fume Exhaust System | Hoods, ducting and an exhaust fan that capture fume at source and deliver it to a scrubber, bag filter or stack. Fan material follows the fume: stainless steel, PP-FRP or rubber lined where it is corrosive. | Backward inclined and radial tipped |
| Ventilation Fan | Moves air through a plant or building for fresh air supply, heat removal and fume dilution where the system is ducted. Low pressure, long hours, so efficiency and noise set the selection. | Backward inclined and forward curved |
| HVAC | Supply, return and exhaust fans for heating, ventilation and air conditioning of plant and office space. Low pressure, so efficiency and noise govern. | Axial, backward inclined and forward curved |
| Roof Extractor | An axial fan in a weatherproof cowl mounted on an inclined or flat roof, exhausting hot air from the ridge of a factory shed. | Axial |
