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 through which the blades rotate. The flow is axial at the inlet and outlet. Propellers rotating around an axis draw air parallel to this axis and push the air out in the same direction. The fan is designed to generate force by creating a pressure difference, causing a flow through the fan. Axial fans create airflow with high flow rate, which creates large amounts of airflow. However, the air flows they create are at low pressure. As the name suggests, these fans are fans that can perform suction. They suck in the dirty air inside and blow out clean air.

• For cooling industrial machines

Things to Consider When Choosing Axial Fan

When selecting a fan, 4 parameters should be taken into consideration;

• Required Air Flow
• Pressure Losses
• Acceptable sound level
• Electrical power connection type

Air exchange required for the environment to be ventilated; It is related to the purpose of use of the environment, the number and activities of the living things and objects in it. The required air exchange coefficients for different environments are given in the side table.

• Q [ m3 / hour ] = Air exchange coefficient (1 hour) * Ambient volume (m3)

Or

• Q [ m3 / hour ] = Number of people * required air flow rate per person

After determining the air flow required in the environment, appropriate duct design should be made (taking into account sound and air speed criteria) and pressure losses should be calculated. Depending on the environment in which the fan will operate, the fan type (axial, radial, roof, smoke extraction, etc.) should be decided and the appropriate fan should be selected from the curve according to the determined flow-static pressure pair. If we briefly explain what is written above and what is in the table with examples; If 5 people work in an office, the ceiling height is 2.6 meters and the floor area is 50 m2, the volume is 2.6 * 50 = 130 m3. The value given for the office in the air exchange coefficient table was 4-8. Let’s take the mean as 5. Air requirement is 130*5=650 m3/h. If we assume that the office works with normal activity, 5 people * 29 m3 = 145 m3 air requirement for employees, resulting in a total air requirement of 650 + 145 = 795 m3 / hour.

Fan selection is made according to this flow rate requirement.

After making the flow calculations, the area where the fan will be installed should be determined. Where will the fan be installed? Like on the ceiling, wall, chimney or ventilation pipe. Another issue is the voltage of the electricity to be connected to the fan. Since we are based on the office in our example, let’s proceed from there. Fans are usually mounted on the wall or glass in offices. If household electricity is to be used, a monophase fan should be preferred. If it is to be used in an industrial area, a fan powered by three-phase (380 Volt) electricity should be used.
