How Can I Identify What Model Fan I Have?

Fan information, such as a model number or serial number, are located on a MacroAir branded sticker somewhere on the fan. Most direct drive models such as the AVD370 have this sticker on top of the motor, while gearbox lines such as the AirVolution have the sticker on the side of the frame around the motor/gearbox assembly. If you have any paperwork on your fan such as your original Purchase Order or Sales Order, your fan information can be found there as well.
