What is a Dust Extraction Fan?
Industries require specialized dust collector fans in their production, manufacturing, or industrial facilities to reduce pollution, keep the work environment clean, and enhance safer working conditions for employees. Different industrial processes produce dust particles of varying sizes; some settle, while others remain suspended in the air. Typical dust extraction fans are fan systems that filter or extract contaminated air. Depending on the type of dust produced by the industrial process, different fan equipment is used to perform various dust collection tasks. Centrifugal fans can handle high-volume dust loads and are, therefore, widely used in industrial processes to extract dust.
Applications
- In areas where dusty air needs to be evacuated
- In duct applications where axial fans are insufficient in pressure and airflow
- General and industrial buildings
- Carpenter workshops
- Polishing machines
- Paint shops
- Factories
- Environments with dust and vapor
- Cooling industrial machines
(e.g., welding machines, transformers, compressors, etc.)

Key Parameters for Fan Selection
When selecting a fan, four key parameters must be considered:
- Required Airflow
- Pressure Losses
- Acceptable Noise Level
- Electrical Power Connection Type
The required air exchange for the ventilated space depends on the purpose of the area, the number and activities of living beings and objects within it. Below is a table showing the necessary air exchange rates for various environments:
| Environment | Air Exchange Rate |
|---|---|
| Auditoriums | 6-8 |
| Paint Booths | 25-50 |
| Vault Rooms | 3-6 |
| Cinemas and Theaters | 5-8 |
| Commercial Kitchens | 15-30 |
| Foundries | 8-15 |
| Gymnasiums | 4-6 |
| Laundries | 10-20 |
| Indoor Pools | 3-4 |
| Restaurants | 8-12 |
| Conference Rooms | 6-8 |
| Waiting Rooms | 10-15 |
| Photocopy Rooms | 10-15 |
| Machine Rooms | 10-40 |
| Shops | 4-8 |
| Dry Cleaners | 5-15 |
| General Manufacturing Areas | 4-8 |
| Hospitals | 8-12 |
| Laboratories | 8-15 |
Air quantities based on activity levels help determine the required airflow for living and working spaces:
- Normal Activity (Non-Smoking): 29 m³/h
- Normal Activity (Smoking): 58 m³/h
- Light Activity: 45 m³/h
- Heavy Activity (Industrial Work Areas): 60 m³/h
The required airflow for the environment is determined using the following formulas:
- Q [m³/h] = Air Exchange Rate (1 hour) × Room Volume (m³)
- Q [m³/h] = Number of People × Airflow per Person
After calculating the required airflow, a proper duct design must be created (considering noise and air velocity criteria), and pressure losses must be calculated. The fan type (axial, radial, roof-mounted, smoke extraction, etc.) should be selected based on the operating environment. The fan curve should then be used to select the appropriate airflow-static pressure combination.
Example Calculation:
In an office with five people, a ceiling height of 2.6 meters, and a floor area of 50 m²:
- Room volume: 2.6 × 50 = 130 m³
- Air exchange rate (office): Assume a value of 5 from the table.
- Required airflow = 130 × 5 = 650 m³/h
- For normal activity: 5 people × 29 m³/person = 145 m³/h
Total required airflow: 650 + 145 = 795 m³/h
Based on this airflow requirement, a fan is selected.
Fan Installation Considerations
Once airflow calculations are completed, the installation location of the fan must be determined. Options include mounting the fan on the ceiling, wall, chimney, or ventilation duct. Another consideration is the voltage of the electricity supply. For offices, single-phase fans (230V) are typically used. In industrial settings, three-phase fans (380V) are more suitable.
