Product Name: Ruitai Feng Environmental Protection Air Conditioner RTF-25C (Top Out Air) Product Features: The core cooling component of Ruitai Feng evaporative air cooler is the high-efficiency evaporative wet curtain - "pure natural multi-layer corrugated fiber composite". By using a fan to blow air indoors, the outdoor air flows through a wet curtain soaked in water, and the air comes into full contact with moisture while absorbing sensible heat from the air, thereby achieving cooling, ventilation, and dust removal. Suitable locations: factory workshops, canteens, dormitories, storage centers, shopping malls, internet cafes, schools, gyms, car dealerships, stations, outdoor activity areas, and animal husbandry cooling equipment and cooling solutions.
