Axico Anti-Stall Vaneaxial Fan Pneumatically Controllable



The FPAC Axico Anti-Stall Fan is a vaneaxial fan with 100% stable operation. It has no stall area and no stall limit. The pneumatically controllable fan can easily deliver the required flow or pressure in most situations by properly sizing the fan and then adjusting the blade angle of attack while the fan is energized. Model FPAC variable air volume fan impellers are equipped with an internal pneumatic diaphragm and external industrial-grade pilot positioner assembly to simultaneously vary the pitch angle of all blades identically while the fan impeller is rotating at motor speed.
