Engineered for ultimate comfort all year long, this fan boasts 6 precise speed settings with a maximum 8500 CFM high-volume airflow, delivering strong and uniform air circulation to cover medium and large-sized rooms efficiently. Equipped with a premium reversible silent motor, it supports forward and reverse rotation operation to adapt to seasonal temperature changes perfectly. In summer, the forward rotation generates refreshing downward airflow to accelerate air convection, quickly cool down indoor temperature and relieve stuffy heat, creating a cool and breathable living environment. In winter, the reverse rotation gently pushes accumulated warm air near the ceiling down to the ground, eliminating temperature stratification, balancing indoor heat distribution, and effectively reducing heating energy consumption to bring warmer and more uniform room temperature while saving household electricity costs.
