Jiangsu Dawang Fans Co., Ltd. (DAWANG FANS) is a manufacturer of intelligent, energy-saving HVLS (High Volume-Low Speed) fans. Since its establishment, the company has been committed to the design, research and development, production, sales, and 4S maintenance of the next-generation ventilation and cooling equipment.
When using a ceiling fan, do not throw anything beneath it. Do not jump off the ceiling fan, and ensure the ceiling is lowered for the fan; prevent people and other objects from coming into contact with the rotating fan, as this may cause mechanical damage.

There are some edge resistors in industrial ceiling fan motors. These resistors should be checked for usage, especially at the contact points. Inspect the fan blades for cracks. If there are cracks that cannot be replaced promptly, the fan blades can easily fly out during use due to the force. The air valve is connected to multiple parts inside the machine. These connections are also prone to loosening. If any screws fall out, they should be replaced immediately. In addition to regular maintenance of the motor based on the above items, a major overhaul is required after one year of operation. The purpose of the inspection is to thoroughly check and maintain the motor, replace missing and worn parts, thoroughly clean dust and dirt inside and outside the motor, inspect the edge condition, clean the bearings, and check their wear. Identify and address issues promptly. At the same time, proper maintenance must be carried out to extend the service life of the motor and better utilize it.

Test the ceiling fan before use when no one is underneath. Through the trial run, ensure there's no swaying or smoke, and no burning smell. If you detect vibrations, noises, or smells during the trial operation, please stop using it immediately, identify the cause, make the necessary repairs, and then continue using it.
Large ceiling fans have excellent heat dissipation performance.
Our energy-saving and environmentally friendly fans should have good heat dissipation performance. After continuous high-speed rotation for more than one hour, the outer shell and front motor housing of the energy-saving and environmentally friendly fans will have some temperature, but will not overheat. If you want to know if the fan meets the standard, you can use a tool to test the temperature.
Dawang Ventilation has established numerous sales and service centers across China, completing production and environmental improvement projects for over 5,000 industrial and commercial sites both domestically and internationally, including FAW, Xizi Elevators, Guangzhou Metro, Taiyuan Heavy Industry Group, and Jordan, among others. Dawang Ventilation's industrial large fans have been widely adopted across various industries, setting industry standards and foundations. They effectively address challenges such as heat and humidity in tall spaces, stratified air currents, and persistent smoke and dust.
