Different Between Fans And Blowers
Both fans and blowers are commonly used equipment for cooling and providing air circulation throughout buildings, internal spaces, outdoor environments, and more. Fans and blowers may seem the same to most people, and at times may be used interchangeably.However, fans and blowers are technically different in terms of their working, structure, function, and applications.
The American Society of Mechanical Engineers (ASME) has defined fans and blowers based on their discharge pressure and suction pressure ratio. This way they have also defined compressors, and in a way distinguished between all these three devices. According to ASME, a fan is a device with a pressure ratio of up to 1.11. A blower has a pressure ratio between 1.11 And 1.2. On the other hand, the pressure ratio in a compressor is more than 1.2. Any kind of ventilation device when operational will bring in air and throw out some air which may also comprise dirt, dust, contaminants, and so on. Industrial blower fans may also be subjected to various oils, chemicals, fumes, high temperatures, and so on depending on the industry type. Here, we do a quick comparison of fans and blowers.
Fans vs Blowers
|
Fans |
Blowers |
|
Have blades for rotation or spinning |
Have impellers for rotation |
|
Are electrical devices |
Are mechanical devices |
|
Consume less electricity |
Tend to consume more electricity comparatively |
|
Provide moderate airflow based on capacity |
Offer better airflow compared to fans |
|
Types include axial fans, industrial axial fans, and propeller fans |
Main categories are centrifugal and positive displacement blowers |
Both assemblies have key benefits that will make them useful in your facility. The unique advantage of selecting a fan is its energy efficiency. They use less electricity than blowers that move the equivalent amount of air. Blowers, on the other hand, are advantageous because of the direct airflow and power they provide. Blowers also have a lower initial purchase price.
Should You Use a Fan or a Blower?
Now that you know more about the different uses and advantages of fans and blowers, you can better select the right fit for your needs. Consider these factors:- Pressure:
- If you need a tool that increases air pressure, choose a blower.
- If you need air pressure to remain the same, choose a fan.
- Power Source and Availability:
- If you have more power available, you can choose a blower.
- If you have less power available, choose a fan.
- Air Flow Requirements:
- If you need to direct air in a specific direction, choose a blower.
- If you need indirect airflow throughout a space, choose a fan.
Based on the particular functions and capabilities you need, there are multiple different fans and blowers to choose from. Fans come in axial, centrifugal, and cross-flow fans, each of which provides different types of air motion; blowers are available in centrifugal and positive displacement models, which use different types of force to move the air from the inlet through the outlet and in a specific direction.
