• 【Four speed regulation】:Designed with 4 speed setting（1417 CFM/3100 CFM/4339 CFM/4963 CFM) to meet different cooling needs. Allows you to enjoy cool convection fresh air in hot summer!
• 【100% BLDC Copper Motor】Our fan uses high-quality pure copper material as the motor winding, ensuring superior conductivity, reducing energy loss, improving motor efficiency, and extending the service life of the motor and fan.
• ★ This BLDC motor has a wide range of voltage adaptability: The fan can effectively cope with voltage fluctuations during use, and can continue to operate normally even in factories or construction sites with unstable power supply.
• ★ The motor is equipped with an intelligent protection chip: when the fan encounters a fault or is obstructed by external forces, causing the rotor to be unable to rotate, the chip will detect and activate the protection mechanism to prevent the motor from overheating or burning out; When the fan is installed improperly or runs idle without installing the fan blades, the chip can also detect and take corresponding measures to protect the motor from damage.
• ★ Energy saving and environmentally friendly: Built in rectifier improves energy efficiency and minimizes power consumption to the greatest extent possible. Compared with traditional AC motors, BLDC industrial fans can effectively save 40% to 80% of electrical energy. If used for 8 hours a day, reducing electricity consumption for a month is equivalent to saving the cost of a fan.
