The FPDA Axico Anti-Stall Fan is a vaneaxial fan with 100% stable operation. It has no stall area and no stall limit. The manually controllable fan can easily deliver the required flow or pressure in most situations by properly sizing the fan and then adjusting the blade angle. The FPDA's constant air volume fan impellers are equipped with mechanically-fixed, individually manually-adjustable blades that may only be re-pitched when the fan is stopped.
