Rundongfang provides customers with a 26000 air volume permanent magnet evaporative air cooler. Environmentally friendly air conditioners, also known as evaporative air coolers, water air conditioners, or water-cooled central air conditioners, are cooling and ventilation units that integrate cooling, ventilation, dust prevention, and odor removal in one. In addition to providing fresh air and lowering temperatures for factory workshops, public places, and commercial entertainment venues, eco-friendly air conditioners have another key feature—energy saving and environmental protection! This is a brand-new green product with no compressor, no Freon, and no copper tubing. Its key components—the evaporative cooling water pad (a multi-layer corrugated fiber composite) and the 1.1KW main motor—consume only 1/8 of the electricity of traditional central air conditioners, delivering truly significant power savings across all industries.

This achieves cooling, ventilation, dust removal, and increased indoor oxygen content, making it especially suitable for high-temperature environments and crowded places. The main application fields are: Industrial: workshops of various automobile plants, hardware plants, electronics plants, machinery plants, electrical appliance plants, motorcycle plants, leather goods plants, garment factories, pharmaceutical plants, textile mills, shoe factories, plastics factories, and other factory workshops. Commercial: shopping malls, internet cafes, schools, stations, gyms, outdoor sports venues, restaurant kitchens, car washes, and more. Agricultural: agricultural-specific models can be used in various greenhouses, flower farms, livestock farms, etc. ![](https://rundongfang.com/wp-content/uploads/products-info-002.png) ### Low Investment, High Performance Compared with installing central air conditioning under the same conditions and area, this eco-friendly air conditioning equipment costs only a fraction of the total central air conditioning investment. ![](https://rundongfang.com/wp-content/uploads/products-info-004.png) ### Low Power Consumption — Only 1 kWh per Hour Compared with central air conditioning of the same area, eco-friendly equipment consumes only a fraction of the electricity required by central air conditioning. ![](https://rundongfang.com/wp-content/uploads/products-info-006.png) ### Good Air Quality “RunDongFang” integrates ventilation, air exchange, dust removal, and cooling in one unit, increasing oxygen content in the space and improving work efficiency, with free choice between natural air supply or targeted spot air supply. ![](https://rundongfang.com/wp-content/uploads/products-info-005.png) ### Powerful Cooling Effect In southern regions, the unit generally achieves a cooling effect of 4℃-10℃, while in hot and dry regions it can achieve 4℃-15℃, and cools down rapidly. ![](https://rundongfang.com/wp-content/uploads/products-info-007.png) ### Large Airflow, Long-Distance Air Delivery Large airflow of 18000 to 60000 cubic meters per hour, selectable according to customer requirements. Our units feature high air pressure and long-distance air delivery. ![](https://rundongfang.com/wp-content/uploads/products-info-008.png) ### Stable Performance, Reliable Quality Equipped with a 100mm thick “5090 evaporative filter pad” for strong cooling capacity, and featuring three-blade forward-swept axial fan blades for low noise and high efficiency. ![](https://rundongfang.com/wp-content/uploads/products-info-003.png) ### Humidity Regulation Regulates humidity in workplaces where increased air humidity is required. Reference air change rates for various settings Definition of air change rate: Air change rate (times/hour) = Total indoor air supply volume (m3/h) ÷ [Indoor area (㎡) × Indoor height (m)]; General environments require an air change rate of 30-40 times per hour; Densely populated public places require an air change rate of 30-40 times per hour; Densely populated, high-temperature locations or production workshops require an air change rate of 40-50 times per hour; High-temperature production workshops with severe pollution require an air change rate of 50-60 times per hour; In more humid southern regions, the air change rate should be appropriately increased, while in hotter northern regions it can be appropriately reduced. The calculation of the number of units depends on the type of air outlet required on site; The selection of models and quantities is flexible according to site conditions; Number of units used = Site volume × air change rate ÷ actual air supply volume of the unit; Spot cooling should be separately configured based on actual conditions, and the total air volume can be appropriately reduced; Indoor air supply ducts must match the model of the air cooler. Based on the actual installation environment and the required number of air outlets, design suitable air supply ducts and outlets - Excellent cooling effect: Can rapidly lower the indoor temperature - Excellent ventilation effect: Effective ventilation and air supply, with high indoor oxygen content - Excellent odor removal: Can promptly eliminate and reduce odors - Excellent air purification: Effectively purifies indoor airborne dust - Excellent harmful gas removal: Can quickly reduce harmful substances indoors ![](https://rundongfang.com/wp-content/uploads/products-info-009.png) ![](https://rundongfang.com/wp-content/uploads/rdf-tongfengjiangwen-jpg-2026-0009.jpg) High evaporation efficiency: The heat exchange area is approximately 100 times the surface area, with excellent water absorption and an evaporation efficiency of over 80%, delivering excellent cooling performance.
