Product description
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, etc.)
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
| 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, 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
Fan selection is also made based on 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.Dündar D Series Axial Fan Housing and Blade Components
