Explosion proof ceiling fan
The ceiling fan is divided into industrial ceiling fan and decorative ceiling fan (called ceiling fan lamp abroad). Most of the domestic families and factories use industrial ceiling fan. Industrial ceiling fans play a major role in China. The main sizes are 1050mm, 1200mm and 1400mm (900mm and 1500mm ceiling fans are seldom seen in the domestic market).
Decorative ceiling fans are mainly used abroad (mainly in the United States, the U. S. government proposes to install ceiling fans in air-conditioned rooms) as an auxiliary electrical equipment for air conditioning. Decorative ceiling fans have beautiful appearance, often equipped with different colors and styles of wind blades and lighting, generally using remote control.
In use, decorative ceiling fan has lower speed and less air volume than traditional industrial ceiling fan, and can be reversed. Its main purpose is to regulate air flow. According to foreign reports, the use of decorative ceiling fans in air-conditioned rooms can save 15% - 35% energy than that without ceiling fans.
