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 exhaust in general and industrial buildings where air temperature is high,
  • 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)

Fan Housing and Blade Components of Axial Exhaust Fans

  • Housing and blade sections manufactured from cold-drawn, high-quality DKP sheet steel,
  • High corrosion resistance with environmentally friendly electrostatic epoxy powder coating,
  • Impeller blades dynamically tested to ISO 1940 standard,
  • Front and rear protection guards conforming to EN 60335-2-80 standards,
  • Slim, compact design with motor and impeller takes up 50% less space than comparable models,
  • Low Noise Level

Motor of Axial Exhaust Fans

  • Quality production without manual handling on high-technology CNC machines,
  • Aluminum-finned motor housing with high thermal conductivity,
  • Rotor balanced to ISO 1940 standards for extended bearing service life,

  • Standards-compliant certified components,
  • IP 54 Protection Class (IP 55 production available on request)
  • Three-phase fans can be used with variable frequency drive (VFD) control.

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 Coefficient
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 Activity (industrial workspaces) 60 m³/h

The amount of air per person in living and working spaces, depending on activity, 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 (1 hour) * Room volume (m³)

Or

  • Q [m³/h] = Number of persons × Air flow rate required per person
After determining the required airflow rate for the space, appropriate duct design (taking into account noise and air velocity criteria) must be carried out and pressure losses must 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 correct fan should be selected from the appropriate fan curve based on the determined flow rate–static pressure pair. To briefly illustrate the above information and the table with an example: 5 people work in an office; with a ceiling height of 2.6 m and a floor area of 50 m², the volume is 2.6 × 50 = 130 m³. The air change coefficient given for an office in the air change coefficient table was 4–8. Let's take an average of 5. This gives an air requirement of 130 × 5 = 650 m³/h. Assuming normal activity in the office, 5 people × 29 m³ = 145 m³ of air is needed for the occupants, giving a total air requirement of 650 + 145 = 795 m³/h.

Fan selection is also made based on this flow rate requirement.

After completing the flow rate calculations, the location where the fan will be installed should be determined. Where will the fan be installed — on the ceiling, wall, chimney, or ventilation pipe? Another consideration is the voltage of the electrical supply to the fan. Taking the office as our example, fans in offices are generally mounted on a wall or window. If standard residential electricity is to be used, a single-phase fan should be selected. For use in an industrial setting, a fan operating on three-phase (380 V) power should be used.
