    Stall in an axial flow fan is a phenomenon due to an increase in the incidence angle at the low flow rates, which obtains unstable characteristics such as performance degradation, vibration, noise, and fluctuation. Consequently, the pressure-flow rate curve shows a saddle-like slope with positive gradients. Anti-stall fin (ASF) could be a revolutionary method to suppress these instabilities. Two-dimensional plates (fins) were attached inside the inlet casing and toward the shaft, so that disadvantages of conventional anti-stall methods, such as structural complexity, cost, installation space, and driving device, were no longer considered in the anti-stall fin. Most of all, the positive gradients on the pressure-flow rate curve were restored to be negative, and expansion of the stall margin could be considered for the axial flow fan with the anti-stall fin. The results were based on the experimental tests.
