Rundongfang provides customers with a 26000 air volume permanent magnet evaporative air cooler. Also known as an evaporative air cooler, water air conditioner, or water-cooled central air conditioner, the eco-friendly air conditioner is a cooling and ventilation unit that integrates cooling, ventilation, dust prevention, and odor removal. In addition to delivering fresh air and lower temperatures for factory workshops, public places, and commercial entertainment venues, eco-friendly air conditioners also have one key advantage — energy saving and environmental protection! This is a brand-new upgraded green product with no compressor, no Freon, and no copper tubing. Its key components are the evaporative cooling pad (a multi-layer corrugated fiber composite) and a 1.1KW main motor, consuming only 1/8 of the electricity of traditional central air conditioners, delivering more practical energy savings for all industries.

It is especially suitable for high-temperature environments and crowded places. Main application areas: Industrial: workshops of 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 plants, and other factory workshops. Commercial: shopping malls, internet cafes, schools, bus stations, gyms, outdoor sports venues, restaurant kitchens, car washes, etc. Agricultural: agricultural-specific models can be used in various greenhouses, flower farms, livestock breeding farms, etc. ![](https://rundongfang.com/wp-content/uploads/products-info-002.png) ### Low Investment, High Efficiency Compared with installing central air conditioning under the same conditions and area, this cooling equipment requires only a fraction of the total investment of central air conditioning. ![](https://rundongfang.com/wp-content/uploads/products-info-004.png) ### Low Power Consumption — Only 1 kWh per Hour Compared with central air conditioning installed over the same area, the power consumption of this eco-friendly cooling equipment is only a fraction of that of central air conditioning. ![](https://rundongfang.com/wp-content/uploads/products-info-006.png) ### Excellent Air Quality “Rundongfang” integrates ventilation, air exchange, dust removal, and cooling in one unit, increasing the oxygen content of the space and improving work efficiency. Natural air supply or targeted spot cooling can be selected as needed. ![](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°C–10°C; in hot, dry regions, it can achieve 4°C–15°C, with rapid cooling. ![](https://rundongfang.com/wp-content/uploads/products-info-007.png) ### Large Airflow, Long-Distance Air Delivery A large airflow of 18000 to 60000 cubic meters per hour is available and can be selected according to customer requirements. Our units feature high air pressure and long-range air delivery. ![](https://rundongfang.com/wp-content/uploads/products-info-008.png) ### Stable Performance, Reliable Quality Uses 100mm-thick “5090 evaporative cooling pads” with strong cooling capacity, and three-blade forward-swept axial fan blades for low noise and high efficiency. ![](https://rundongfang.com/wp-content/uploads/products-info-003.png) ### Humidity Adjustment Adjusts humidity in workplaces where increased air humidity is needed. Reference air change rates for various settings Definition of air change rate: Air change rate (changes/hour) = total indoor air supply volume (m3/h) ÷ [indoor area (㎡) × indoor height (m)]; General environments require 30-40 air changes per hour; Crowded public places require 30-40 air changes per hour; Crowded and high-temperature locations or production workshops require 40-50 air changes per hour; High-temperature production workshops with severe pollution require 50-60 air changes per hour; In the more humid southern regions, the air change rate should be appropriately increased, while in the hotter northern regions it can be appropriately reduced. The method for calculating the number of units depends on the type of air outlets required on site; The selection of unit models and quantities is flexible based on site conditions; Number of units = site volume × air change rate ÷ actual air supply volume of the unit; Spot cooling should be separately configured according to actual conditions, and the total air volume can be appropriately reduced; Indoor air supply ducts must match the air cooler model. Based on the actual installation environment and the required number of air outlets, design suitable air supply ducts and outlets. - Excellent cooling effect: rapidly lowers indoor temperature - Excellent ventilation effect: effective ventilation and air supply, high indoor oxygen content - Excellent odor removal: promptly eliminates and reduces odors - Excellent air purification: effectively purifies indoor dust from the air - Excellent harmful gas removal: quickly reduces 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 outstanding cooling performance.
