Very good upload, thank you. For contaminated air extractor (example spray booth aplication), would backward curved centrifugal be better than axial fan, size for size power for power ofc? Also, which one could be quieter, if similar silencer methods are used? Thank you.
Better is axial fan in these application,Backward curved blades will accumulate dirt easily and it's difficult to clean.when it comes to noise axial fan creates more noise.If the application is high pressure and low volume go for centrifugal fan.if the application is low pressure and high volume ,then go for axial fan
Though backward-curved impellers are the most efficient in ideal conditions, they are prone to having contaminants build up on the various surfaces and edges of the blades. This buildup will _massively_ reduce their efficiency over a short amount of time. However, the backward-inclined design is less susceptible to this buildup on the surfaces, and the radial design is even less susceptible to buildup on the surfaces as well as on the edges, so even though they start with less efficiency, they will require much less cleaning maintenance than the backward-curved impeller and maintain their efficiency longer. There are also some applications where impellers with leading edges (backward-curved, backward-inclined, and forward-curved) would be directly damaged by the materials being blown through the fan. This is why radial impellers are used in contaminated air applications, as the blades "sweep" the air instead of "cut". The oldest boiler we still run at the plant (installed in the 60s) has a backward-inclined forced-draft fan supplying air to the burners and a forward-curved induced-draft fan directing the exhaust out the stack. The F.D. fan tends to get some lint buildup in the housing and on the leading blade edges (we handle textiles) but the I.D. fan stays very clean because any lint, dust, or other debris that gets through burns in the firebox.
Nicely explained
Thank you so much 🙂
very helpful for a beginner. Thank you
Glad it was helpful!
Good information ji sir tq so much

@@engineeringmaster9214 thank you 👍
Great
Many many Thnks
Pls can you advise me the best companies that supplier Centrifugal fans (V.belt drive,1500 RPM)

I dont understand the theory behind the decisions of choosing anything other than the Backward-curved impeller?
The price must be the same?
Impellers are selected based on application .I have compared about different impellers in this video itself.

Tell me the name of software that you use for this animation?
Blender
Can I download it and put it on my website?
No.
@@engineeringmaster9214 ok
Hi how can i reach u? i need help for my thesis project thank you
Yes ..you can ask me
Can you pls share me how to design a centrifugal fan include: the diameter of fan, thickness of fan.... Thanks for sharing.
