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 general and industrial buildings where ambient temperatures are 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)

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 rate required for the space to be ventilated depends on the intended use of the space, the number of people and items inside, and their activity levels. The table alongside shows the recommended air change coefficients for different types of 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 work areas)	60 m³/h

Per-person air volumes in living and working spaces based on activity level 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)
Q [m³/h] = Number of persons × Air flow rate required per person

Once the required air flow rate for the space has been determined, an appropriate duct design (taking into account noise and air velocity criteria) must be made and pressure losses calculated. Depending on the environment in which the fan will operate, the fan type (axial, radial, roof, smoke extraction, etc.) must be decided, and the appropriate fan should be selected from the fan curve based on the determined flow rate–static pressure pair. To briefly illustrate the above with an example: an office has 5 employees, a ceiling height of 2.6 m, and a floor area of 50 m², giving a volume of 2.6 × 50 = 130 m³. The air change coefficient table gives a value of 4–8 for offices. Taking an average of 5: 130 × 5 = 650 m³/h air requirement. Assuming normal activity in the office, 5 people × 29 m³ = 145 m³ of air is needed for the occupants, for a total of 650 + 145 = 795 m³/h air requirement.

Fan selection is made according to this flow rate requirement.

After performing the flow rate calculations, the location where the fan will be installed must be determined. Where will the fan be mounted — on the ceiling, wall, chimney, or ventilation duct, etc.? Another consideration is the voltage of the electricity supply to the fan. Since we used an office as our example, let us continue with that. Fans are generally wall- or glass-mounted in offices. If standard household electricity is to be used, a single-phase fan should be preferred. If the fan is to be used in an industrial setting, a fan operating on three-phase (380 V) electricity should be used.
