About Anhui Guangde towards Cheng Machinery Co., Ltd. is located in the industrial park-German Economic and Technology, Anhui, Zhejiang and Jiangsu provinces at the junction, geographic location. The company from Hangzhou, Hefei, Nanjing, capital is only two hours away. In Central, East provides a convenient excellent service and product sales. Anhui Wannan is the largest-scale production of ventilation equipment technology enterprises. This is a company specializing in research, development, design, manufacture of high-tech companies, high-temperature fire fans supporting motor production technology enterprises, the production of exhaust valves, fire dampers, muffler, HIP me, and other ventilation equipment in the field of backbone enterprises. Ventilation equipment has many years of design and manufacturing experience, through continuous efforts, through continuous research and development and the introduction of advanced products, has successfully broadened the scope of fans and other products, is already the country with a certain amount of professional ventilation equipment manufacturers. The company specializes in producing low-noise cabinet centrifugal fan, low-noise wind chassis, duct fans, fire temperature exhaust fan, mixing (oblique) flow fan, square wall fans, axial roof fan, centrifugal roof fans, induced fan, jet fan, subway wind magnesium composite duct, fan and valves and other fire products through the National Fire Equipment Quality Supervision and Inspection Center. Companies with new development, enhance their core competitiveness; quality of survival, and continue to create a high degree of performance; energy-efficient, and take the strategic objectives of sustainable development. Research and development of products using CFD and CAD software for the fan to simulate the flow field analysis to obtain the performance is more excellent products. Companies "advanced technology, improve the detection, inspection norms", enhanced product control standards; and require the company product standards higher than the national or industry standards. Fans of traditional technology is relatively backward, the company mold parts, operation mechanization and become an advanced enterprise in the ventilation industry. In this "sincerity toward the fan." Special thanks to product development, design process have been Fluid Machinery Research Institute, Xi'an Jiaotong University, Zhejiang University School of fluids associated Machinery Research Institute, Shanghai Jiaotong University School of Power and active, Shanghai Jiaotong University School of Automation, Telecom, etc. technical support and communication school and experts, improve product efficiency, energy saving, low noise performance and fan-controlled device implementation and optimization system for users to make some contribution to energy saving and emission reduction units. Good customer service and user visit system, improve the technical service system, so that customers feel towards sincere fan brand concept. Sincerity towards fans, the times, and sincerely welcome friends to visit, guidance!
