Axial fans are industrial exhaust fans with common applications. They have a high flow rate, creating airflow parallel to the fan shaft. In which case is the axial fan used? Find out in the article below.
Industrial axial fans
Basic introduction
Axial fans have a square box or round cylindrical design. There are 2 directions of suction and blowing parallel to the fan shaft. Depending on the manufacturer, either a DC axial fan or an AC axial fan is produced.
Axial fans have 2 types according to their structure: direct axial fans, and indirect axial fans (They differ in the structure of the motor connected to the propeller, directly or indirectly).
Or classified by pressure, there are 3 types as follows: a high-pressure axial fan, low-pressure axial fan, and medium voltage axial fan.
Structure of the fan
The fan has a simple structure. Includes the following main ingredients:
✔️ Fan motor: The motor is an important device responsible for operating the fan.
✔️ Propeller: The propeller is the part that generates the wind. Usually made of cast aluminum, stainless steel, or thermoplastic… (At System Fan, axial fan blades are made of stainless steel …) Depending on the requirements to be met, it is possible to produce blades with different numbers of blades. . From 2 to 20 blades on one propeller.
✔️ Fan cover: The fan cover is a part of the frame that protects the fan from the effects of the environment, avoiding the impact…
There are also ball bearings, flanges, brackets, silencers…
Axial fan operation
Working principle of axial fan
Axial fan when operating creates large mechanical airflow. Depending on the capacity of each fan, the airflow is also different. The propeller rotates around the fan shaft. Creates an airflow that sucks in dust and dirt, and the air in the space enters through the suction direction of the fan. and come out on the other side.
Axial propellers work similarly to airplane wings. With the structure of the aircraft, when the propeller rotates, the air above and below is divided with different air velocities. The air above flies out more due to the high air velocity, creating a large dynamic, low static pressure. In contrast, the air in the lower part has low velocity, and high static pressure. This difference will create a lift that helps the plane to fly in the air.
Axial fans also have such a mechanism. The rotating axial propeller creates a force that pushes the air forward creating lift. As a result, the air is drawn in at one end and blown out at the other end of the fan.
With this circulation, the fan can absorb the filter and circulate the air easily.
Application of axial fan
With continuous operation sucking at one end and blowing out at the other end. Axial fan is used for cooling and circulating air as follows:
👉 Used for cooling in systems, machines, factories
👉 Cooling for transformers, generators, and other industrial electrical equipment.
👉 Vacuuming, ventilation for factories, warehouses, basements…
👉 Limit unpleasant odors in air-tight areas
👉 Installation of ventilation for shopping centers
👉 Use cooling in hospitals, schools, public areas, crowded people
…
In addition, industrial axial fans can be used for filtering harmful gases and dust such as:
👉 Using paint dust collector in spray booths
👉 Suction toxic gas from welding machines
👉 Vacuuming dust, toxic gases from kilns, metallurgical furnaces, brick kilns…
👉 Factories that generate dust like paper factories
👉 Vacuuming from food and pharmaceutical factories
….
It can be said that axial fans have important applications in life and production. Used as a dust collection device, exhaust gas for exhaust gas treatment systems, and industrial dust collection systems.
Thanks to that, at present, axial fans are the fan line that many people are interested in and purchase. System Fan provides high-quality, efficient industrial axial fan products. Let’s find out on System Fan Global.
