Fans and blowers are both commonly used cooling devices today. Many people consider these two fan lines to be the same. They are sometimes used interchangeably. However, technically, fans and blowers have different structures, functions and applications. What is the difference between fan and blower? Let’s find out more in this article.
Fans and blowers
Fan and blower are often referred to as interchangeable terms. However, in terms of structure and characteristics, they have differences.
Fan is a device used to create air flow under the action of propeller rotating on the air. Fan blades help create airflow with low pressure
A blower is a device used to produce large amounts of air with a moderate increase in pressure. Used to supply air at a specific location.
Difference between fan and blower
Fan |
Blower fan |
Used to circulate air in open spaces, air is blown out in all directions. |
Used to direct air flow in a specific direction |
Fan size is usually smaller than blower fan |
Big size |
Uses little pressure to produce a large amount of gas |
Using high pressure to produce a large amount of gas |
Pressure ratio below 1.11 |
Pressure ratio from 1.11 to 1.2 |
Complete area air supply |
Supply air at a specific location or point |
There are different types of fans such as:
– Axial fans
– Centrifugal fan |
Popular types are:
– Centrifugal blower
– Positive displacement blower |
Should I use a fan or a blower?
Should you choose a fan or a blower is a question many people ask. Now, after you know the difference between a fan and a blower, you should be able to answer this question, right? In addition, we share some more information below to help you choose the right fan or blower.
Do you need an air pressure booster?
– If you need equipment to increase air pressure, choose a blower.
– If you need to maintain the air pressure, you should choose a fan
Heavy power to consume less or more?
– If you have a lot of power available, you can use a blower,
– If there is little power, use a fan.
What kind of airflow do you need?
– If air flow in a specific direction is required, choose a blower
– If you want the air to spread throughout the space, choose a fan.
The above is the difference between fan and blower. Based on the needs of use, users can choose the appropriate fan or blower.
