Dust Extraction System
We also undertake the designing, manufacturing, supply and installations of entire Dust Extraction Systems which entails the preparation of layout of the duct routing and fabrication of the ducts to fit site conditions. This exercise involves engineering the duct design as well as that of the Hoods or dust extraction points, to ensure the required velocity is maintained and the system is balance for pressure drops resulting in the optimal performance of the entire system.
Advantages
- Have a high collection efficiency of dust
- Can have high air-to-cloth ratio (0.8 to 1.4 m3/min/m2)
- Have increased efficiency and minimal residual dust buildup due to aggressive cleaning action
- Can clean continuously
- Can use strong woven bags
- Have lower bag wear
- Have small size and fewer bags because of high air-to-cloth ratio
- Some designs allow bag changing without entering bag house
- Have low pressure drop for equivalent collection efficiencies
Disadvantages
- Require use of dry compressed air
- May not be used readily in high temperatures unless special fabrics are used
- Cannot be used if high moisture content or humidity levels are present in the exhaust gases
