SWF Series Francis (oblique flow) is a new fan centrifugal fan axial flow between applications oblique meridional flow acceleration method (also known as mixed flow fan) design temperature between Francis fan, it combines the advantages of both pressure compared with the same machine number of high axial fans, air volume compared with the same machine number large centrifugal fan with high efficiency, efficient wide area, low noise, compact structure, convenient installation. Fans of the series points single-speed and two-speed two models, you can change the angle of the wind turbine installation according to different occasions, to change the number of leaves and conversion speed reaches its requirements. Francis fan structure and characteristics: The basic structure of the type of inlet and outlet on the same axis (ie axial flow structure) Francis fan models, round shell as cones, leaves of varying width along the flow direction was like. There are straight cylindrical shape, a drum-shaped and curved plus three types of mufflers and other imports. According to the meridional flow acceleration principle, the fan has dual characteristics of centrifugal and axial flow, that is both high pressure have a larger flow and mixed flow fan with high efficiency, low noise and efficient wide area and so on. Francis fan selection of compact, light weight, easy installation, small footprint. Francis fan temperature, up Swiss mechanical and electrical (certified), Inner Mongolia Francis fan ventilation and air conditioning provided by the Swiss liter Electrical Equipment Factory. L Rui HVAC Electrical Equipment Factory (www.dzsrxfkt.com) is a leader in Dezhou, fans, ventilation equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. L Swiss leader in mechanical and electrical staff warmly welcome all inquiries negotiations to create liter Swiss electromechanical a better future.
