Products (1) overall streamline arc, it is necessary to ensure ventilation body strength, is also effective in reducing ventilation body exposed to the formation of the large volume of the wind pressure ventilators body height and arc, and effectively improve the indoor air collection and emissions ability. The roof ventilators snow load capacity depends on the form of the design of the steel frame, the thickness of the material specifications of the steel frame and hood cover and other factors, including the choice of component materials specifications is very important, should first guarantee to meet wind and snow load requirements, while also Avoid unnecessary use large size. Product attributes to prevent the intrusion of rain and snow on the roof ventilators basic requirements. Peripheral fender, hood cover and the standardization of the pan of water board installation and construction is the the ventilation the rainproof ability of important guarantee: (1) the board is in place, according to the design drawings. Should generally years to reverse the position of the maximum frequency of wind direction as the installation starting point. (2), to determine the installation direction, the end edges of the sealing plate to install fixed, then the first plate is mounted in place, and fixed, to ensure that the vertical and purlins. (3), the second plate should be installed with the projections of the first plate along the overlap, by checking to ensure full contact of the outer edge of the two plates and flat, thus ensuring overlap intact, and with a ring of self-tapping screws purlin connected together. (4) between the color steel C purlin tapping galvanized screws, (5), fixed reliable or not directly related to the number of connections, spacing, connection quality. Set waterproof sealing material at the laying of the well in order to ensure inter-board water leakage phenomenon does not occur. The use fan no electricity, no impatient tone, and long-term operation. According to the the air natural laws and the principle of airflow, rationalization set in the top of the roof, the rapid discharge of hot air and polluted indoor gas to improve the indoor environment. Installation, maintenance, Liaocheng Sunshine Stainless Steel Co., Ltd. is currently the only company specializing in the production of roof ventilation equipment manufacturers. In recent years, under the joint efforts of the engineering and technical personnel, factory production of free electricity --- roof ventilation is currently one of the domestic specifications largest and most complete variety of manufacturers. 300, 360, 450 with residential buildings, the villa floor roof ventilation mouth, 500, 600, Model 680 is mainly used for exhaust ventilation plant workshop and large public places. All stainless steel body, cast aluminum support special double sealed bearings. World-class product sales over the face of the country, after-sales service. Windmill - wind pumps fuel, no electricity, manufacturing, and that is able to start. High tower fan blade diameter of 5-10 meters, all nine specifications can be designed according to the different needs of production. Colorful the weathervane widely used in the park, and the edge of the green belt, villas and corporate production environment, it can not only indicate the wind direction and speed levels can also add a dynamic and harmonious environment. The face of strong competition in the market, our factory always adhere to manufacture high quality products for the guidelines, adhere to honesty, excellent service up to the largest customer satisfaction Notes product characteristics: low noise · air volume, high efficiency · wind pressure stability · color soft Guangyan, enduring applications and suitable for industrial and mining enterprises, civil construction of the ventilation and cooling the other explanatory use of nature's natural wind power roof ventilators promote the fan turbine rotation and the indoor and outdoor air convection principle. Device on the roof of the factory, very good ventilation effect. Description of a transaction, deal face to face 2, online trading 3 auction Buy transaction
