What Is an Axial Fan?

An axial fan is a type of fan that causes air to flow in an axial direction parallel to the shaft around which the blades rotate. The flow is axial at both inlet and outlet. The blades rotating around an axis draw air parallel to that axis and push it outward in the same direction. The fan is designed to generate force by creating a pressure difference, inducing airflow through the fan. Axial fans produce high-velocity airflow, which generates a large volume of air movement. However, the airflow they produce is at low pressure. As the name suggests, these fans are suction-type fans; they draw in stale indoor air and blow out fresh air.

Fan Housing and Impeller

  • Casing and fan blades made of cold-drawn, high-quality DKP sheet steel,
  • High corrosion resistance with environmentally friendly electrostatic epoxy powder coating,
  • Impeller blades dynamically balanced to ISO 1940 standards, rear protection guard compliant with EN 60335-2-80 standards,
  • With a slim, compact design, the motor and impeller take up 50% less space than comparable units
  • Takes up less space,
  • Low Noise Level

Motor

  • Quality production without manual handling on high-technology CNC machines,
  • Aluminum-finned motor casing with high thermal conductivity,
  • Rotor balanced to ISO 1940 standards for extended bearing service life,
  • 400 V / 50 Hz single-phase fan motor. Click here for the three-phase fan.
  • Standards-compliant certified components,
  • IP 54 protection class (IP 55 production option available on request)
  • Variable frequency drive (VFD) control can be used with three-phase fans ***

Applications

  • Hot air exhaust in high-temperature environments,
  • For accelerating heat transfer at evaporators or condensers,
  • Cooling of industrial machinery

Things to Consider When Selecting an Axial 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 changes required for the space to be ventilated depend on the intended use of the space, the number of occupants and objects inside, and their activities. The table alongside provides the required air change rate coefficients for different environments.
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 Activity (industrial work areas) 60 m³/h

The amount of air per person in living and working spaces depending 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 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 noise and air velocity criteria into account) should be made and pressure losses calculated. The fan type (axial, radial, roof, smoke extraction, etc.) should be decided based on the operating environment, and the appropriate fan should be selected from the relevant fan curve according to 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 meters, and a floor area of 50 m², giving a volume of 2.6 × 50 = 130 m³. The air change rate coefficient given for an office in the table is 4–8; let's take 5. 130 × 5 = 650 m³/h air requirement. If we assume normal activity in the office, 5 people × 29 m³ = 145 m³ for employees, giving a total of 650 + 145 = 795 m³/h air requirement.

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

After completing the flow rate calculations, the installation location of the fan should be determined. Where will the fan be mounted — ceiling, wall, chimney, or ventilation duct? Another consideration is the voltage of the electrical supply to the fan. Continuing with our office example: fans in offices are generally mounted on a wall or glass. If a domestic electricity supply is used, a single-phase fan should be preferred. If it is to be used in an industrial setting, a fan operating on three-phase (380 V) power should be used.
