Product description

What Is an Axial Fan?

Where Are Dündar K Series Axial Fans Used?

• Axial fans are widely used for ventilation in residential and commercial spaces.
• These fans offer a practical solution for the ventilation needs of small areas and operate quietly.
• Thanks to the rear shutter, when the fan is not in use the indoor space is isolated from the outside, preventing unwanted elements such as dust and cold air from entering.
• Hot air extraction in areas with high air temperatures, removal of odors and smoke from homes,
• Stale air extraction in offices,
• Environments with dust and vapor,
• In areas of homes where airflow is insufficient,
• In classrooms,
• In smoking environments,

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 COEFFICIENT
Classrooms	5-7
Libraries	4-5
Domestic kitchens	15-25
Bathrooms	5-7
Domestic restrooms	4-5
Public restrooms	8-15
Conference rooms	6-8
Offices	4-8
Changing rooms	6-8

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




Normal Activity (Non-Smoking)	29 m³/h
Normal Activity (Smoking)	58 m³/h
Light Activity	45 m³/h
Heavy Activity	60 m³/h







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.
