Dawangfan’s large garage ceiling fans are able to perform exhaust in large areas increasing curbside airflow while being effective in garages, warehouses and other commercial spaces. The performance of the fans increase only when external temperatures require such, enabling the fans to keep a low temperature while circulating a large amount of air with low movement. In putting its considerable amount in use we not only reduce the cost of running a room large ventilator but also get a chance to invest overtime into energy wastes on a business scale. The use of IoT technology allows the users to have a complete overview and control of the fan settings. This ensures the best performance in line with the demand.
