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.

Applications

For small and medium-sized spaces:
Suitable for ventilating bathrooms, toilets, kitchens, pantries, laundry rooms, garages, workplaces, etc.
It is manufactured specifically for ceiling ventilation applications, to be used together with a duct connection pipe attached to the extractor.

Features

It is an indispensable choice for spaces where a stylish and wide front appearance is desired to create a striking impression.
Manufactured from high-quality ABS plastic, our product provides the best protection against bad odors, moisture, and similar external factors while never losing its original appearance.
With its wide air sweep path body and optimum fan design, noise levels have been reduced to a minimum.
The specially designed body and front cover provide high suction from all directions while keeping the front cover clean at all times.
We can manufacture our exhaust fan at the desired flow rate and speed to suit the application environment. (120 m³/h ~ 150 m³/h)
The air outlet flap provides the best protection against dust, odors, and cold that could enter from outside when the fan is not in use, while also preventing heat loss from inside to outside.
It can be made dual-speed upon request.
The dust-exposed filter can be removed very easily and cleaned by wiping or washing.
Self-lubricating, maintenance-free motor bearings provide quiet and long-lasting performance.
It has IP24 protection against water splashing.
The motor is in insulation Class H.
Our products are manufactured in accordance with EN 60335-2-80, Low Voltage Equipment [2006/95/EC] and Electromagnetic Compatibility [2004/108/EC] standards.

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 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 (With 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)

Q [ m³/h ] = Number of people × Air flow rate required per person

After calculating the required air flow rate, an appropriate duct design (considering noise and air velocity criteria) must be carried out and pressure losses must be calculated. Depending on the environment in which the fan will operate, the fan type (axial, centrifugal, roof-mounted, smoke exhaust, etc.) should be selected, and the appropriate fan should be chosen from the relevant performance curve based on 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 m, and a floor area of 50 m², giving a volume of 2.6 × 50 = 130 m³. The air change rate given for offices in the air change coefficient table was 4–8. Taking an average of 5: 130 × 5 = 650 m³/h air requirement. Assuming normal activity in the office: 5 persons × 29 m³ = 145 m³ for the occupants, 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 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.
