max excel 10" pro inline fan (with speed controller)

The Max-Excel® is the first fan that has been developed with a Computational Fluid Dynamics (CFD) program. CFDs are used for engineering aircraft propulsion engines. The perfectly designed 3D blades of the impeller and stator make this fan extremely powerful and energy-efficient. Compared with other inline fans, efficiency is 50%-100% higher. 6″ – 14″ come pre-wired with an 8 ft 120 V power cord. Excel-Fan® bring its innovation to market and sets a new standard for performance. The Max-Excel® is a more powerful and efficient fan that takes less energy to run
