Q-Max EC is a turbine or mixed flow fan with the highest aerodynamic efficiency and the best level of energy consumption, thanks to the new motor and EC technology, together with the 3D rotor stator system . The system of rotor, stator and two propellers makes Max-Fan one of the most powerful fans on the market, as well as having low noise and minimum power consumption. The rotor has the task of pushing the air out creating a vortex, while the stator transforms this vortex into a uniform jet of air thus avoiding pressure losses, with an efficiency rate 50% higher than any aspirator, a single propeller conventional.
