Cooling fan Features: ◆ blinds; high strength galvanized plate, using a unique device louvers automatically open Yancheng cool wind turbine, (push pull closing mechanism); ensure fully open and close blinds, under any circumstances to maintain 90 ° open, make blinds reach not choke, wind, rain, dust; ◆ blinds push pull closing mechanism: the excellent toughness industrial nylon injection molding, high strength, long life; the guide bar inlaid metal, increased strength of the guide bar, and enhance the reliability and service life of the opening and closing mechanism. Curtain fan cooling fan Description: curtain fan cooling system of special porous paper curtain, water system and axial fan components. Curtain and fan were installed in a closed room should be the opposite sides of the gable; the fan ventilation, causing indoor vacuum cooling fan manufacturers, forcing the outdoor air flow through unsaturated porous curtain wetted surface, causing the water to draw a lot of latent heat of evaporation, thereby reducing the temperature of the air itself, thus the steady flow of hot air into the room to cool. Curtain fan cooling system equipment is simple, low investment and operating costs of a large cooling load capacity, only one-tenth the cost of running the air conditioning unit. Cooling fan manufacturers, Qingzhou Minhua temperature control equipment (certified), the cooling fan is provided by the people of China Qingzhou temperature control equipment plant. Temperature Control Equipment Factory Qingzhou public Hua (www.minhuawenkong.com) (www.minhuawenkong.com) (www.minhuawenkong.com123) is an industry leader in Shandong Weifang, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation development, the principle of honesty and trustworthiness, and satisfy customer needs.
