Air blowers can suck in air and drag it outside. They are similar to reverse windmills and contain a number of blades attached to an impeller. These blades keep spinning, leading to the drawing of polluted air and replacing it.
Do you need to purchase the best blower fan for your workspace? Let us help you decide on one by telling you all about the functions of such devices and how they work.
There are two types of air blowers, and they include axial fans and industrial centrifugal fans. These are both used in commercial setups as well as in homes. Often large machines have centrifugal blowers attached to them to remove hot air.

Industrial centrifugal fans allow high pressure of air to build up, which is then released through the other side of the unit. This is perfect for large-scale applications like the cement industry, where pollutants need to be removed continuously. The air blower will blow the contaminants outside and keep the air clean inside.
Now typical centrifugal fans contain:
1. Centrifugal Fan Casing
This is an essential part of the centrifugal fan system as it consists of the main fanning gears. The centrifugal force of the fan is generated here as well, and this section is well-protected. You will find a hard casing being used which does not break easily.
2. Outlet And Inlet Ducts
The inlet ducts control the movement of air inside the centrifugal fans. They are usually attached to the air blowers in the front. The outlet ducts on the other side are connected to the rear end. These ducts assist the air that is leaving the air blower.
3. Fan Blades
Fan blades are responsible for transferring the air through the fans. These blades are curved in shape, and you will find a number of aerodynamic designs on the market. Fan blades aid the drying process by moving air quickly from the inner area to outside.
The motor uses electrical energy to put more pressure on the incoming air that the air blower sends. It is responsible for the high airflow and is crucial to the fan.
Impellers contain numerous fan blades, and they allow the air to circulate properly. The shape of the air blades may vary on the basis of the fan shape.
6. Rotor Shaft
This shaft connects the motor with the blades, and it regulates the fan speed. Hence, blowing air would not be possible without a rotor shaft.
How Can You Differentiate Between An Air Blower And A Fan?
Fans are responsible for air circulation over a specific area. They work in a simple manner and push air around to keep the atmosphere cooler. Now, you might be thinking, why is my ceiling fan not blowing air? This happens if the fan blade rotation is incorrect. If your fan is moving in a clockwise direction, you may not be able to feel the airflow too much.
Moving on, air blowers ensure direct air movement towards a certain area.
These are more controlled and have great suction pressure. They use spinning blades to pull in the air and then remove it through the back. Hence, these are used for ventilation systems where air needs to be discharged.
Common Factors Between Fans And Blowers
If you are looking to move the air in a wet space and ensure quick drying, then air blowers should work well. You will find exhaust fans in bathrooms which are used to dry up the surrounding area.
Now for those wondering how exhaust systems or air blowers work, let us tell you that moisture is captured by air, but only a certain amount can be held. If you keep an air blower fan switched on at high speed, it will remove the moisture-laden air from the space. It will then be replaced by clean air that can absorb more moisture.
Having an extremely hot day and wanting some respite from it? A fan is your best bet. It can ensure the cooling of a large area, and you can now get modern features with it. Remote control can be used to control the fan and change the speed from where you are seated.
Now, if you are wondering what direction do fans blow, let us tell you that fans are supposed to move counterclockwise. This helps in creating a downdraft that leads to a cooling breeze. On the other hand, in winter, you will need the fans to move in a clockwise direction. This leads to an updraft that will circulate warm air in the room.
Air blowers are perfect for use in workshops. You will mostly be working with different materials, and you can expect a lot of dust, dirt, and wood dust to be in the air. An air blower can be used to increase the airflow in the area and remove the pollutant-laden air inside. You can use this for commercial applications as well, where large-scale work is happening.
If you are in charge of a fire pit or barbeque, then it is best to get air blowers for the place. Barbeques require more oxygen, and air blower fans can direct the airflow better. In fact, modern barbeques contain small air blowers that can help in lighting up the grill.
A hot kitchen can feel very suffocating to work in, but blower fans can help improve the air quality. They can remove the hot and humid air inside the kitchens, along with the smoke rising up from the food.
How Does A Blower Fan Work Frequently Asked Questions ?
Is a fan less efficient than a blower fan?
Blowers are less energy efficient when compared to fans but are hugely used in industrial equipment and for industrial applications. A fan is cheaper, but it does not create any suction pressure. On the other hand, a blower is often used by mechanical engineers to discharge polluted air.
What does a blower motor do?
If you can attach blower motors to fans, then they will convert the fans into HVAC systems. This will lead the air into the rooms after the air leaves the systems. The blower motor is responsible for controlling the temperature that is set on the thermostat in your house.
Also, blower motors are present inside air conditioning systems. These have rotating fan wheels, which remove warm air from inside the room. Go through our other article on how to test ac blower fan motor to know more on blower motors.

You will find centrifugal fans in most blowers, and they are quite powerful. They are often attached to a belt which means you can operate at higher and lower speeds. Plus, you can then get higher efficiency for lower operations.
On the other hand, for fans that are typically driven by motors, you can get higher power at greater strain. These fans are highly efficient and are made with top-quality materials. Also, the impellers rotate faster, which leads to higher pressures.
This can move air at high speeds, making it very important for industries and commercial hubs for high-pressure applications.
And almost all blowers have centrifugal fans that are optimized depending on the specific usage. A centrifugal blower fan can be used for drying, getting fresh air, cooling, inflating, etc.
Just make sure you choose the right option for the job at hand.
