The round frame AC fan is an efficient indoor environment renewal device, which is developed and manufactured by Wah Yan Wing Plastic & Electronic Co. The fan has the following characteristics:

1. Energy-saving and high efficiency: the round frame AC fan adopts the working principle of energy conversion of electrical energy→electromagnetic energy→mechanical energy→kinetic energy, with high theoretical power and good heavy-duty characteristics, which requires less electrical energy to achieve high-efficiency operation, and it can play an excellent performance in high-temperature or odourous industrial production workshops and other places.

2. Low noise: Supported by ball bearings, the rotating speed is low and even, and the louvres are windproof, dustproof and rainproof, which effectively reduces the noise and will not cause interference to the surrounding environment.

3. Easy to maintain: the structure of the round frame AC fan is simple, easy to maintain and clean, only need to regularly replace the filter and clean the fan to keep it in good running condition.

4. Wide range of application: the round frame AC fan is suitable for commercial factories, supermarkets, offices, hotels, hospitals, stations, gymnasiums, dance halls, auditoriums, conference rooms, schools, factories, etc. It is especially suitable for high-temperature or odourous industrial workshops, as well as flower greenhouses, breeding and other places of the overall cooling and ventilation.

5. Safe and reliable: The round frame AC fan adopts negative pressure to extract air with super suction, exchange indoor and outdoor air, discharge heat, odour and dirty air, and introduce fresh air, so that the indoor temperature can be reduced to the same as the outdoor temperature, which ensures the safety and reliability of use.

All in all, the round frame AC fan is a high-efficiency, energy-saving, low-noise, easy-to-maintain, widely-applicable, safe and reliable equipment for renewing the indoor environment.
