Introduction
Industrial fans พัดลมอุตสาหกรรม are a key component of lots of industries—from manufacturing and processing to HVAC and ventilation systems. These handy machines are used chiefly in the movement of air, controlling temperatures, and making sure work-settings are in good condition in various environments. In this blog post, we look into main types of these industrial fans and applications in different places.
Types Of Industrial Fans
Centrifugal Fans
Centrifugal fans, also known as radial fans, are among the most popular types of industrial fans พัดลมอุตสาหกรรม. These fans use a turning impeller to pull air in from the side and throw it out radially, or toward the blade, by means of the frame of the fan.
Centrifugal fans are known for being capable of producing high pressures and are generally applied in applications that require moving large amounts of air against resistance big enough to cause a sharp drop in pressure. Such applications can be found in HVAC systems, industrial ovens, dust collection systems etc.
Axial Fans
Axial fans, in contrast, move air in a linear direction. These fans incorporate blades shaped like an airplane propeller and quickly whisk air out of the fan. Axial fans are normally more efficient however when pressure ratios are low and flow rates are high such as in cooling systems, ventilation, and air circulation.
Plenum Fans
A plenum fan is a variation that could be considered a noisier whirlwind cousin of the axial fan.
A plenum fan is a fan that is designed to operate in low pressure environments, such as the plenum chambers of HVAC systems in commercial and industrial buildings. They tend to have low profiles, that is, they extend outward from surfaces with a small amount of extension into the room, and are engineered to perform in tight spaces without limiting flow.
Applications
HVAC Systems
The air circulated and distributed in a building by fans in a Heating, Ventilation, and Air Conditioning (HVAC) system. Main air handling units contain the centrifugal fans, and rooftop units and air conditioning systems house axial fans.
Dust Collection and Filtration
In any industrial setting where lots of dust and particles are produced, such as woodworking, metalworking and mining, it’s necessary for the security of the area and the health of the workers to have systems in place that collect and filter the air.
These cleaning systems aren’t complete without industrial fans to draw in dirty air, pump it through the cleaning system of the company and blow it out the other side clean as can be.
Process Cooling
Plants in any manufacturing, chemical processing, or power generation industry that are exothermic, or produce heat as a byproduct, must have effective ways to eliminate excess heat.
Industrial fans help facilitate heat transfer, by circulating the air and forcing cooler air into contact with the heat exchange surfaces, helping machines and other heat driven systems operate more safely.
Ventilation and Air Circulation
In lots of industries, separate from the HVAC systems, you may also need various fans originating inside the plant equipment for the purposes of air movement.
Some of the things you need to consider when you’re using fans strictly for air movement are where you’re going to place them to maximize efficiency, the amount of filters in the equipment you’re emptying into, and how the dust is trapped in the equipment and the filters, because if not properly exhausted and collected, could blow out with the air movement and become airborne.
Material Handling
In industries that involve moving the bulk materials of any kind, such as the processing of mining, agriculture, and construction, industrial fans come into play with the transporting of those materials.
In these situations, there are fans that create the movement by creating the airflow that actually grabs and carries those lumps of minerals through pipes or other material handling systems.
Fume and Smoke Extraction
Some industries require special industrial fans and operating systems in order to remove toxic fumes, smoke, or dust from the work environment.
For instance, welding, painting, blasting, and chemical processing all create problematic smells, fogs, and fumes that need to be cleared away, and no companies want their workers to be harmed by these contaminants, so their may use fans and vacuum systems, and sometimes fans used especially in those class environments are engineered to be spark proof and/or operable in the most corrosive of atmospheres.
Conclusion
Industrial fans are so versatile and needful items in many types of industries, that size alone doesn’t limit the wide range of times they’re put into service at the factory.
From centrifugal and axial fans all the way to plenum fans and fan applications I barely grazed the surface of, the family of industrial fans is a vast and diverse family of fans.
Even as we develop ways to make parts and systems cleaner and environmentally safer, the need for more and more creative and efficient industrial fan solutions grows.
