I am struggling with setting of bcs for axial fan. The methodology used is MRF for rotating part and stationary zone for remaing cell zones.
General setup - Absolute Velocity formulation
Cell Zone conditions-
rotating zone - MRF /5000 rpm/ (Relative to cell zone- absolute)
stationary zone - 0 rpm /(Relative to cell zone- absolute)
inlet - pressure inlet / default conditions
outlet - pressure outlet / default conditions
After 5000 iterations if I see the the pressure contour the range observed is -2.664 - +2.66 atm ...and velocity (0 - 693.19 m/s )...
Is it correct ? any suggestions are welcome..

I would suggest asking this in the FLUENT forum, and you should get much better answers (probably you need to provide a bit more information).
However, if the velocity you are reporting is with respect to a stationary frame of reference, then you can check it with the fan tip speed (fan radius * fan rotational velocity) to see if it is in the ball park.
For the pressure range, what is the driving pressure difference?
