Our HVLS industrial fan, is equipped with a self-developed direct-drive system of high torque and low speed, matched with a domestic top frequency converter to bring natural wind with low energy consumption (0.3kW/hr) to help ventilate surrounding air and reduce temperature. The fan cooperates with air conditioner and other ventilation systems well to distribute or move air to areas that needs it, creating the most energy-saving ecological environment with constant temperature and humidity. This product was also designed to function on a wireless network, allowing it to be controlled by a mobile application. Safer - Without a need for Gearbox, the transmission chain is shortened, allowing the system to run more smoothly and have a longer lifespan. - Gearless transmission greatly reduces the weight and unnecessary parts allowing the product to be safer when in use. Quieter - Low-speed motion during operation for less vibration, less noise. Low Maintenance - The system has fewer components leading to a more convenient installation, less maintenance and lower maintenance cost. Energy-saving - Low-speed and high-torque direct drive system improves the efficiency of the system and greatly reduce energy usage.
