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 on 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, causing flow through the fan. Axial fans produce airflow with a high flow rate, generating large volumes of airflow. However, the airflow they produce is at low pressure.

Where Are Dündar D Series Axial Fans Used?

Can be easily mounted in a ventilation opening cut in your chimney or wall.

Axial fans are widely used for ventilation in residential and commercial spaces. These fans offer a practical and economical solution for the ventilation needs of small areas and operate with low noise.
Due to the low-pressure, high-volume airflow they generate, axial fans are used for general-purpose applications — for example, moving or cooling air coming from one location.
Used for ventilating enclosed spaces.
Hot air exhaust in high-temperature environments, removal of odors and smoke in homes,
Stale air extraction in offices
Environments with dust, cigarette smoke, and vapor,
Cooling industrial machinery (welding machines, transformers, compressors),

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 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 workspaces)	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 (considering noise and air velocity criteria) must be prepared and pressure losses must be calculated. Depending on the environment in which the fan will operate, the fan type (axial, centrifugal, roof, smoke exhaust, etc.) should be decided upon, and the appropriate fan should be selected from the fan curve based on the established flow rate–static pressure pair. To briefly illustrate the above with an example using the table: 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 coefficient from the table for an office was 4–8; let's take an average of 5. This gives 130 × 5 = 650 m³/h of air requirement. Assuming normal activity in the office, 5 persons × 29 m³ = 145 m³ for the occupants, for a total air requirement of 650 + 145 = 795 m³/h.

Fan selection is made according to this flow rate requirement.

After completing the flow rate calculations, the installation location of the fan must 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 the fan. Since we are using an office as our example, let's continue from there. Fans are generally mounted on walls or windows in offices. If domestic 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) power should be used.
