I Ordered A 10' AirLite, But Actually Needed A 14'. Can I Order Larger Blades?

The AirLite fan line has a diameter range of 8'-14' in increments of 2'. However, sizes are determined by the gearbox ratio rather than VFD programming. Each diameter has a different gearbox ratio. If a different size is needed, a different motor and gearbox is needed.
