The process
Stenters circulate hot air through the fabric in each chamber with plug fans and exhaust the moist air carrying oil mist and lint. Exhaust fans and ducts are built for cleaning, with mist elimination or scrubbing where the oil load is high.
The gas
Air saturated with moisture from drying, with condensation on any cool surface. Drainage, a shaft seal and a material that tolerates wet running are part of the specification.
Fans in this process
| Duty | What it does here | Type usually selected |
|---|---|---|
| Hot Air Fan | Circulates or supplies air at elevated temperature to a dryer, oven or kiln. | Backward curved and backward inclined |
| Plug Fan | A centrifugal impeller without a scroll, plugged through the wall of an oven, dryer or air handling unit so it recirculates the air inside the chamber. | Backward curved |
| 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 |
| Mist Eliminator | Separates entrained liquid droplets from a vapour or gas stream, ahead of a compressor, a fan or a stack.. | Demister Knockdown Vessel |
| 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 |
