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 under 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.

Industrial ceiling fan blades are typically manufactured through extrusion processes. Although the quality of extrusion is lower than that of bending, it meets the requirements for mass production and, with proper management, can still ensure the quality of the blades. Aluminum alloy extrusion for fan blades also varies in methods. Depending on the difference between the direction of metal flow during extrusion and the direction of the extrusion die movement, it can be categorized into forward extrusion, backward extrusion, and joint extrusion. During extrusion, the application of extrusion force is in the opposite direction to the product's流出 direction, which is known as the backward extrusion method. Currently, most manufacturers use forward extrusion to produce aluminum alloy fan blades, but the backward extrusion method offers more advantages.
Industrial ceiling fans, when used in conjunction with air conditioning, can increase the oxygen content in indoor air, alleviating the feeling of oxygen deficiency caused by long-term air conditioning use. They can raise the temperature by 1-2 degrees without compromising comfort, and when used together, they can reduce operating costs by 50%. Industrial ceiling fans are more suitable for large spaces over 4.5 meters high and are not suitable for small spaces. Installed on the ceiling, they pose no electrical hazards and are visually appealing.

Check the ceiling fan after about a year of use. Inspect the吊杆、screws、terminal block、blades, etc., for any signs of looseness, corrosion, cracks, deformation, or other anomalies. Tighten any loose screws immediately and replace any damaged parts as needed.
Da Wang Ventilation has established numerous sales service centers across China, completing production and environmental improvement projects for over 5,000 industrial and commercial sites both domestically and internationally.
