Good news｜Fans-tech obtained the National Invention Patent

    Recently, "A closed-loop feedback precise ventilation high-efficiency fan and fan control method" independently developed by Fans-tech obtained the invention patent authorization (certificate number: 5706725).

    The invention integrates high-efficiency paddle-type ventilation rotors, air volume test feedback devices, and air valve devices that can be linked to adjust the angle of the air valve blades, so that the fan of the present invention can measure the actual ventilation volume in real time, and achieve timely and accurate feedback of the air volume in the ventilation system , and adjust the motor output and/or adjust the angle of the damper blades according to the actual ventilation volume fed back, so as to maintain efficient, stable and accurate air volume output under higher pressure conditions.
