The process
Spinning mills run humidification plants that hold the department at the right humidity and waste collection systems that draw lint and fly from the machines into rotary filters. Large volumes of air at low pressure, with fibre that wraps a wheel.
The gas
Fibrous or stringy material that wraps a shrouded wheel. An open or straight radial impeller, spark resistant where the fibre is combustible, placed before or after the collector as the material allows.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| Dust Collector Fan | The fan behind a bag filter, cyclone or multiclone on a dust extraction system. | Backward inclined and radial tipped |
| Bag Filter Fan | Pulls the process gas through the filter bags and discharges the cleaned gas to the stack. | Backward curved and radial tipped |
| HVAC | Supply, return and exhaust fans for heating, ventilation and air conditioning of plant and office space. | Axial, backward inclined and forward curved |
| 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 |
| AHU | A packaged unit with fan, filters, cooling or heating coil and mixing box that conditions and delivers supply air. | Backward curved and forward curved |
