Speed regulation methods significantly impact energy consumption: VFD (variable frequency drive) provides the best energy savings, reducing power proportionally to the cube of speed reduction. Damper control is less efficient as it wastes energy through restriction. VFD can save 20-50% energy at reduced loads.
