The process
Mixers, extruders and calenders release fume and fine filler dust. Local extraction to filters and carbon adsorption, with plant ventilation for the heat.
The gas
Air carrying solvent vapour from painting, printing or coating. Spark resistant construction, flameproof or increased safety motor, and the fan placed where the duct cannot accumulate vapour.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| Fume Exhaust System | Hoods, ducting and an exhaust fan that capture fume at source and deliver it to a scrubber, bag filter or stack. | Backward inclined and radial tipped |
| Dust Collector Fan | The fan behind a bag filter, cyclone or multiclone on a dust extraction system. | 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. | Backward inclined and forward curved |
| HVAC | Supply, return and exhaust fans for heating, ventilation and air conditioning of plant and office space. | Axial, backward inclined and forward curved |
