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.

AREAS OF USE

In spaces of various sizes
Used for ventilating factories, workshops, paint shops, cabinets, garages, greenhouses, enclosed animal shelters, electrical panels, and similar locations.
Designed to exhaust stale and contaminated air or to supply fresh air from outside to inside.

Features

The body and impeller are made from galvanized steel sheet; thanks to the electrostatic paint applied, the product is resistant to erosion, heat, and moisture.
The product has a minimum vibration level and has successfully passed dynamic and static balance tests conducted in accordance with ISO 1940 standards.
Protection against external factors is provided by the chrome-plated wire guard on the rear.
With the optimized body and impeller design, higher pressure is achieved at the same flow rate while noise levels are minimized.
Wall, metal plate
can be easily mounted vertically or horizontally on windows and similar surfaces.
With models in different sizes, it is suitable for use in spaces of various dimensions.

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)

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.
