What Is an Axial Fan?

An axial fan is a type of fan that causes air to flow axially, parallel to the shaft on which the blades rotate. Flow is axial at both inlet and outlet. Blades rotating around an axis draw air parallel to that axis and push it out in the same direction. The fan is designed to generate force by creating a pressure difference, resulting in flow through the fan. Axial fans produce high-velocity airflow, generating large volumes of air movement. However, the airflow they produce is at low pressure. Blower and cooling axial fans, as the name suggests, create a cooling effect by blowing air over hot surfaces.

Where Are Industrial Axial Fans Used?

  • Axial fans are widely used for ventilation and cooling in industrial, residential, and commercial settings.
  • They are very well suited for applications requiring high airflow rates.
  • Thanks to specially designed blade structures developed with advanced software technology, high airflow rates are achieved at minimum noise levels.
  • Hot air extraction in high-temperature environments, general and industrial buildings,
  • Warehouses, stockrooms, and storage facilities,
  • Garages and public buildings, agricultural buildings,
  • Commercial greenhouses,
  • Large workshops,
  • Paint shops,
  • Factories,
  • Environments containing dust and vapor,
  • Cooling of industrial machinery (welding machines, transformers, compressors)

Points to Consider When Selecting an Axial Exhaust Fan

4 parameters should be considered when selecting a fan:
  • Required Air Flow Rate
  • Pressure Losses
  • Acceptable Noise Level
  • Electrical Power Connection Type
The air change required for the space to be ventilated depends on the intended use of the space, the number of occupants and items inside it, and their activities. The table alongside shows the required air change coefficients for different spaces.

Environment Air Change Rate
Auditoriums 6-8
Paint Ovens 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 Swimming Pools 3-4
Restaurants 8-12
Conference Rooms 6-8
Waiting Rooms 4-6
Copy Rooms 10-15
Machine Rooms 10-40
Shops 4-8
Dry Cleaning 5-15
General Manufacturing Areas 4-8
Hospitals 8-12
Laboratories 8-15
Normal Activity (non-smoking) 29 m³/h
Normal Activity (smoking) 58 m³/h
Light Activity 45 m³/h
Heavy Duty (Industrial workspaces) 60 m³/h

Depending on the activity, the amount of air per person in living and working spaces can help determine the required air flow rate.

Based on the information provided above, the required air flow rate is determined as follows.

  • Q [ m³/h ] = Air change rate coefficient (1 hour) × Space volume (m³)

Or

  • Q [ m³/h ] = Number of people × Air flow rate required per person
After determining the required air flow rate for the space, an appropriate duct design (taking into account noise and air velocity criteria) should be made and pressure losses should be calculated. Depending on the environment in which the fan will operate, the fan type (axial, radial, roof, smoke extraction, etc.) should be decided upon, and the appropriate fan should be selected from the fan curve based on the determined flow rate–static pressure pair. To give a brief example of the above and the table: an office has 5 people working in it, the ceiling height is 2.6 m, and the floor area is 50 m², giving a volume of 2.6 × 50 = 130 m³. The air change coefficient given for an office in the table was 4–8; let us take an average of 5. The air requirement is 130 × 5 = 650 m³/h. If we assume normal activity in the office, 5 people × 29 m³ = 145 m³ of air is needed for the occupants, giving a total of 650 + 145 = 795 m³/h of air requirement.

Fan selection is made according to this flow rate requirement.

After performing the flow rate calculations, the installation location of the fan should be determined. Where will the fan be mounted — on the ceiling, wall, chimney, or ventilation duct? Another consideration is the voltage of the electrical supply to be connected to the fan. Taking an office as our example, let's proceed from there. Fans are typically mounted on walls or windows in offices. If single-phase power is to be used, a single-phase fan should be preferred. For use in an industrial setting, a fan operating on three-phase (380 V) power should be used.
