Jiangsu Dawang Ventilation (DAWANG FAN®) specializes in HVLS energy-saving fans, with diameters ranging from 3.6 to 8.5 meters. An 8.5-meter flagship fan delivers a full-load airflow of approximately 21,800 m³/min, with motor noise ≤ 38 dB. , is one of the alternative solutions for large-space ventilation and cooling.

Jiangsu Dawang Ventilation Machinery Co., Ltd. (DAWANG FAN®), established in 2015, is a specialized manufacturer of HVLS smart IoT-enabled ultra-large energy-saving fans. The company integrates design, R&D, production, sales, and operations & maintenance, independently researching and producing large industrial energy-saving fans across the entire value chain. The enterprise possesses Over 45 patents , has served Over 8,000 customers worldwide Product realization: IoT-enabled smart connectivity, supporting remote control, temperature and humidity interlocking, and fire safety integration, complemented by a standardized 4S maintenance service system that covers the equipment’s entire lifecycle.

How to choose among the six major product lines?

The first consideration when selecting a fan is the installation type: choose a ceiling fan if there’s a ceiling with mounting points; opt for a pedestal or wall-mounted model if there’s no ceiling; and select a portable unit if you need flexibility to move it around.

Utility model patents related to safety include Fall-arrest device, shock-absorbing buffer structure, permanent-magnet synchronous motor and so on. The company also holds after-sales service certification, and its integrated 4S maintenance system covers the entire lifecycle of its equipment.

What spaces are they installed in?

DaWang ventilation large fans are commonly used in three types of settings. Factory workshop Use it in place of a small fan for ventilation and cooling, as well as air circulation, to alleviate issues caused by high temperatures, stuffiness, lack of oxygen, and unpleasant odors and exhaust gases; when used with an air conditioner, it can further reduce energy consumption. Commercial complexes, venues It generates a continuous, gentle, natural breeze that accelerates sweat evaporation from the body’s surface, providing a cooling sensation, while also promoting fresh-air exchange between indoors and outdoors. In some steel‑structured industrial buildings, it is used to create three-dimensional air circulation, reducing condensation on roofs.

How do you choose based on space?

With a ceiling height of over 4 meters, large floor space, and dispersed personnel or equipment Factories, Warehouses, Venues, Commercial Complexes It is more effective to use a large ceiling fan in conjunction with air conditioning to achieve further energy savings. In small, enclosed rooms with a ceiling height of less than 3 meters and limited space, the installation and airflow benefits of a large ceiling fan are limited; such spaces are better suited to small wall-mounted fans or air conditioners.

Good ventilation isn’t about cranking the fan to full blast; it’s about ensuring air flows evenly throughout the space. Dawang Ventilation has turned this into a quantifiable engineering solution.
