In fluid dynamics, a stall is a reduction in the lift coefficient generated by a foil as angle of attack increases.This occurs when the critical angle of attack of the foil is exceeded. Fan Stall Stall is aerodynamic phenomenon which occurs when a fan operates beyond its performance limits and flow separation occurs around the blade. The stall region in axial fans is nowadays an accepted although undesirable phenomena in the industry.
