Radial Fan – Definition and Applications
What is a Radial Fan?
Fans that create a pressure difference are called radial fans. The airflow generated operates based on centrifugal force. A centrifugal fan is a mechanical device used to move air or other gases. These fans contain a rotating impeller and a helical housing similar to a pump. Air or gas enters parallel to the axis at the center, is pressurized, and is then transferred tangentially to the channels around the impeller before being expelled through the outlet.
Due to the high pressure they generate, centrifugal fans are ideal for high-pressure applications such as drying and air conditioning systems. Additionally, since all moving parts are enclosed, they are well-suited for air pollution control and filtration systems due to their particle reduction properties.
APPLICATION AREAS
Suitable for small and medium-sized spaces, including:
- Bathrooms, toilets, kitchens, homes, offices, workplaces, pantries, garages, etc.
- Designed particularly for ducted ventilation applications and air transfers between rooms.
FEATURES
- Designed to expel air directly outside or through a short duct. The duct should be straight and shorter than 1.5 meters.
- Engineered for low static pressure conditions to ensure airflow in small and medium-sized spaces.
- Can be used in both flexible and rigid ducts.
- Manufactured from high-quality ABS plastic, ensuring protection against bad odors, humidity, and other external factors while maintaining its original appearance.
- Optimized fan design minimizes noise levels while ensuring high-pressure air suction.
- Easily installed on walls, ceilings, windows, and inside ductwork.
- Self-lubricating, maintenance-free motor bearings ensure quiet and long-lasting performance.
- Equipped with IPX2 protection against water splashes.
- Class-II protection, eliminating the need for grounding.
- Manufactured in compliance with EN 60335-2-80, Low Voltage Equipment (2006/95/EC), and Electromagnetic Compatibility (2004/108/EC) standards.

Key Considerations When Choosing an Axial Fan
When selecting a fan, four key parameters must be taken into account:
- Required Airflow Capacity (m³/h)
- Pressure Losses
- Acceptable Noise Level
- Electrical Power Supply Type
The necessary air exchange for ventilation depends on the intended use of the space, the number of occupants, furniture, and activities performed. The following table provides recommended air change rates for different environments:
Environment | Air Change Rate (per hour) |
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 |
Airflow Calculation
Based on the given data, the required airflow is determined using the following formulas:
Formula 1:Q[m3/h]=Air Change Rate×Room Volume(m3)
Q \, [m^3/h] = \text{Air Change Rate} \times \text{Room Volume} (m^3)
Q[m3/h]=Air Change Rate×Room Volume(m3)
Formula 2:
Q[m3/h]=Number of People×Air Requirement Per Person
Q \, [m^3/h] = \text{Number of People} \times \text{Air Requirement Per Person}
Q[m3/h]=Number of People×Air Requirement Per Person
Air Requirement Per Person Based on Activity:
- Normal Activity (Non-Smoking) → 29 m³/h
- Normal Activity (Smoking) → 58 m³/h
- Light Activity → 45 m³/h
- Heavy Activity → 60 m³/h
Example Calculation
Consider an office with 5 occupants and a floor area of 50 m² with a ceiling height of 2.6 m:
Room Volume
=2.6×50=130 m3\text{Room Volume} = 2.6 \times 50 = 130 \, m^3Room Volume=2.6×50=130m3
Using an air change rate of 5 for an office:
130×5=650 m3/h
130 \times 5 = 650 \, m^3/h
130×5=650m3/h
Considering the normal activity level of employees:
5×29=145 m3/h
5 \times 29 = 145 \, m^3/h
5×29=145m3/h
Total required airflow: 650+145=795 m3/h
650 + 145 = 795 \, m^3/h
650+145=795m3/h
A fan should be selected based on this airflow requirement.
Installation Considerations
- Determine where the fan will be installed: Ceiling, wall, duct, or exhaust pipe?
- Ensure proper electrical supply voltage:
- For home/office use: Single-phase (230V) fan.
- For industrial applications: Three-phase (380V) fan.
