Intelligent operation modes: The intelligent programming function of the room to room fan provides three control modes: cooling trigger mode, heating trigger mode, and continuous mode. You can customize ventilation solutions according to seasonal needs to improve energy efficiency and comfort. Enhanced airflow performance: Featuring dual seven-blade fans, this room to room transfer fan delivers a robust airflow of 300 CFM, optimizing air circulation between rooms without disruptive noise. The airflow generated by the two fans is in opposite directions, creating better airflow circulation, realizing more effective air circulation and ventilation effects, and creating a more comfortable indoor environment.
