Centrifugal fans and blowers have become a favorite choice for most of the industrial applications as a result of their relatively more straightforward design, durability, functionality, and higher efficacy.
As a standard centrifugal fan gets the ability to grow the speed of air flow coming through it, those fans are extensively utilized in industrial processes where large movement of gas or air is necessary.
To get the desired ruthless and volume presses, businesses utilize various kinds of centrifugal fans (Also known as “พัดลมแบบแรงเหวี่ยง” in the Thai language) with varied blade settings in series and parallel arrangements.
Yet, they may well not attain the desirable air flow movement which is required for that industrial process as a result of their reduced performance.
A centrifugal fan could have performance deficiencies predicated on the device design because there could be losses due to multiple structures of system components and their proximity to the inlet and outlet.
Fan performance is usually tested to standards by thinking about the perfect inlet and discharge venting conditions.
Some motives for the inferior operation of centrifugal fans are:
Non-uniform inlet flow
Airflow to the inlet needs to be straight and smooth in a uniform mode without any disturbance.
In case the atmosphere isn’t drawn in an evenly distributed shape, there will uneven load onto the fan wheels and also the consequence could be irregular, turbulent flow of air stream throughout the system.

Spinning atmosphere at the fan inlet
Another element that affects the operation is that the management of the airflow stepping into the wheel.
Air stepping into the fan can have a turning effect because of improper positioning of system components at the fan inlet.
Improper duct work at the socket
Duct work on the fan outlet has an excellent effect in performance. To achieve better efficacy, the release duct should be directly and have proper length & uniform cross section. The duct has to be near the outlet for smooth and evenly distributed airflow.
