I Ordered A 14' AirVolution, But Actually Needed A 16'. Can I Order Larger Blades?

The AirVolution and AirLegacy fan lines have a diameter range of 8'-24' in increments of 2', except for 22'. However, sizes are determined by the gearbox ratio rather than VFD programming. Each diameter has a different gearbox ratio, and some have different horsepower motors. If a different size is needed, a different motor and gearbox is needed.
