Learn More About Technical Systems: Compressor, Blower, or Fan?

You should remember that we can easily segment turbomachinery based on the way it extracts or adds energy. Apart from energy, it is important to move and compress a fluid. In some situations, if the fluid is a specific gas, then the turbomachinery system can be either a compressor, blower, or fan.

The main idea is to understand the differences between these devices and when you should use them. Of course, we recommend you understand that we cannot provide you with a standard answer, meaning the processes can vary based on the country you reside in and the industry.

The facts state that some definitions are arbitrary, while others are relevant. The general rule states that the industry recognizes differences between compressors, blowers, and fans. We recommend you to check here to learn more about energy requirements for Heating, Air Conditioning and Ventilation systems.

Although these devices can generate a pressure rise in gas and provide you with a corresponding flow capability, they feature specific differences including pressure rise and applications among other things.

That is why you should understand each option before making up your mind. We recommend you stay with us to learn more about the differences that will provide you with additional insight. Let us start from the beginning.


You should remember that fans feature pressure ratios of 1.11. We are talking about pressure ratio, which is the combination of discharge pressure with the fan inlet pressure, which is something that we can also call suction pressure.

Generally, pressure ratios of 1.11 and lower are not as effective in the turbomachinery world, which is important to remember. The main idea is to consider a fan a device that will help you create a forced convection cooling of your skin because it will move the air across your area by using a certain, pre-determined velocity.

The best way to visualize is by considering the fan you are using in the room to keep you cool throughout the hot summer days. As you can see, the pressure increases are small compared with other devices we will mention in a further post.

The fan can overcome regular losses including the blading, resistance, and other parts of it such as downstream mixing and fan cage among other things. The pressure will go either downstream or upstream of the entire ambient, meaning the pressure rise will overcome the overall losses you will experience.

Remember that the pressure ratio for fans can be low, meaning the pressure rise will not depend on the overall ratio. That is why these devices can help you move large amounts of gas without increasing the overall pressure of the room’s air, which is vital to remember for industrial purposes and requirements.


You should remember that most people use the blower interchangeably with fans. However, it comes with higher pressure than a fan, meaning you will achieve the 1.2 option. The main idea is to ensure that the pressure rise depends on the discharge pressure combined with the inlet pressure.

That is why by visiting this website: https://www.serafimaint.com/ you will learn the ways to maintain your blower, fan, or compressor systems, which is vital to remember. It will help you picture a blower as a relevant device that will help you move a gas by using resistance such as ducting, which features higher resistance than a regular fan.

Of course, you have probably heard about hair dryers or blow dryers, which must overcome high system losses compared with regular fans, while you can accelerate the flow by using a specified nozzle for the process. In best cases, the blower is a device that can move significant levels of air across moderate resistance systems, which is vital to remember.


If you wish greater pressure for specific applications, you should use a compressor, because you will ensure the compression of the pressure, which will be greater than 1.2. The facts state that the main goal of a compressor is to boost the gas pressure, instead of moving it into a large amount as other options mentioned above.

A common example is a turbocharger you have in a vehicle. For instance, a turbocharger compressor can operate at a 3.5 pressure ratio, which will help you compress the air into the engine. In this application option, the system requires a higher-pressure level for thermodynamic properties and reasons.

If you wish to use it for other purposes, system losses will become much higher, meaning you will need a significant rise in pressure to overcome the process. The overall flow rate is small compared with furnace blowers or other options you can find on the market. Pressure ratios that are higher than 1.2 are common for compressors, especially if you use centrifugal.

You can also achieve options that can reach above ten in a single stage. Therefore, you should think of compressors as devices that will offer you a considerable pressure rise, which will boost the flow rates altogether.

Importance of Fans for Industrial Applications

You probably understand that we can differentiate numerous options when it comes to industrial fans and the way we mount them. We are talking about freestanding fans, panel and wall-mounted options, duct fans, and blowers. Each one comes with a specific purpose or function that will benefit your business.

For instance, freestanding fans do not require mounting. They are highly versatile compared with other industrial options because you can place them anywhere to boost air circulation and cool down the air that surrounds you. The category can include various portable options when it comes to blowers and industrial fans.

You should remember that a panel and wall-mounted options will enter the wall with the idea t ventilate a particular area. They will come with exhaust fans, which will remove unpleasant odors and harmful gases by using wall openings.

Blower and duct fans come in the form of duct monitoring, meaning you should mount them by using flanges or braces. Exhaust fans are also part of them, meaning ceiling ventilation options can be mounted inside the systems. They are highly effective for dealing with harmful fumes and hazardous emissions.
