Our company’s fans fully meet your requirements for various parameters such as air volume and air pressure, and have a service life of over 25 years. The following are our product quality assurance measures:

From the receipt of raw materials to the shipment of finished products, all processes are rigorously inspected in accordance with the ISO9001 international quality system standards. The production, inspection, testing, and acceptance of each process are jointly carried out by the Production Department, Quality Inspection Department, and Technical Department, with detailed records kept and filed. We provide end-to-end tracking, quality management, and service for every customer’s product. For example, the design and manufacture of fans comply with GB/T 3235 “Basic Types, Dimensions, Parameters, and Performance Curves of Fans” and GB/T 3235 “Basic Types, Dimensions, and Parameters of Fans.” Purchased motors must meet the technical requirements specified in GB/T 3836.1. Product outgoing tests are conducted according to the GB/T 1236—2000 standard, covering ductwork processing, measurement point layout, raw data acquisition, data calculation, and result output. Steel materials must be accompanied by material certification reports provided by the manufacturer, and we also commission nationally recognized, qualified inspection agencies to verify the material composition; only materials that meet the required standards can be used. For matched motors, the motor manufacturer must provide performance test reports and no-load test reports. We provide customers with non-destructive testing reports for fan blades. Fan impellers undergo two-sided dynamic balancing tests in accordance with GB/T 9101 “Balancing of Fan Rotors,” and the outgoing dynamic balancing grade must reach G5.6 or higher—exceeding the national standard requirements. Upon shipment, we provide customers with dynamic balancing test reports for the impellers. The exterior painting of fans is performed according to the technical requirements specified in JB/T 6886 “Technical Conditions for Fan Painting.” Fan nameplates are manufactured in compliance with the requirements of GB/T 13306 “Nameplates.”
