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. Airflow is axial at both the inlet and outlet. The fan blades draw air parallel to the axis and push it out in the same direction. Axial fans generate airflow with high volume and low pressure by creating a pressure difference, which induces flow.
Applications of Dündar D Series Axial Fans:
- Easy Installation: Can be easily mounted on chimneys or wall ventilation openings.
- Ventilation: Commonly used in residential and commercial spaces for ventilation.
- Quiet Operation: Provides practical and economical solutions for small spaces while maintaining low noise levels.
- General Purpose: Ideal for moving air, cooling, and extracting heat in areas with low pressure but high airflow volume.
Common Applications:
- Ventilation of enclosed spaces.
- Hot air extraction in high-temperature environments.
- Removing odors and smoke in homes.
- Exhausting polluted air in offices.
- Removing dust, cigarette smoke, and vapor.
- Cooling industrial machinery (e.g., welding machines, transformers, compressors).
Key Considerations for Fan Selection:
When selecting a fan, consider the following four parameters:
- Required Airflow (m³/h)
- Pressure Losses
- Acceptable Noise Levels
- Type of Electrical Power Connection
Calculating Required Airflow:
The required airflow for a ventilated space depends on its usage, the number of people and items inside, and their activities. The table below shows air change coefficients for different environments:Environment | Air Change Coefficient |
|---|---|
| Classrooms | 5-7 |
| Libraries | 4-5 |
| Home Kitchens | 15-25 |
| Bathrooms | 5-7 |
| Home Toilets | 4-5 |
| Public Restrooms | 8-15 |
| Meeting Rooms | 6-8 |
| Offices | 4-8 |
| Changing Rooms | 6-8 |
Per Person Air Requirements:
- Normal Activity (Non-Smoking): 29 m³/h
- Normal Activity (Smoking): 58 m³/h
- Light Activity: 45 m³/h
- Heavy Activity: 60 m³/h
Airflow Calculation Example:
For an office space:- Room dimensions: 50 m² floor area, 2.6 m ceiling height → 50 × 2.6 = 130 m³.
- Air change coefficient: 5 (from table).
- Required airflow: 130 × 5 = 650 m³/h.
- Add airflow per person: 5 people × 29 m³/h = 145 m³/h.
- Total required airflow: 650 + 145 = 795 m³/h.
The fan should be selected based on this calculated airflow requirement.
Installation Location:
Determine the installation location—ceiling, wall, chimney, or ventilation duct. Additionally, consider the voltage:
- Single-phase (230V) fans for residential use.
- Three-phase (380V) fans for industrial applications.
