Maximum Centrifugal Fan Outlet Velocity
Maximum Centrifugal Fan Outlet Velocity
(OP)
Most specifications inherited from grandfathers have an outlet velocity limitation of 10~12 m/s for centrifugal fans.Does anyone know what is the basis for this limit?Couldn't we use a higher out velocity (say 16 m/s )for fan selection?This may result in a smaller fan.An expansion fitting can be used to connect the fan to duct work and bring down it down to duct velocity(which could be around 10m/s).
Any thoughts???

Therefore need to confirm if efficiency or cost is of greater importance to the project.

Dynamic balancing of fans becomes even more important, a small wear of the fan shaft or small chip on a fan blade will result into a large imbalance and will create serious vibrations.
The slower, the better.
