Product Quality Commitment and Guarantee

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 time raw materials enter the factory to the moment products leave the factory, all processes are rigorously inspected in accordance with the JSO901 international quality system standards. The production department, quality inspection department, and technical team jointly carry out production, inspection, testing, and final acceptance at each stage, and all activities are meticulously recorded 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/T3235 “Basic Types, Dimensions, Parameters, and Performance Curves of Fans” and GB/T3235 “Basic Types, Dimensions, and Parameters of Fans.” All purchased motors must meet the technical requirements specified in GBT361. Product outgoing tests are conducted according to...
The pipeline network processing, measurement point layout, raw data acquisition, data calculation, and result output shall be carried out in accordance with the GB/T1356—20 standard. For steel products, manufacturers are required to provide material certification reports, and the materials must also be inspected by a qualified inspection agency accredited by the state. Only materials that meet the specified requirements may be used. For self-priming motors, motor manufacturers must provide performance test reports and no-load test reports. Users shall be provided with non-destructive testing reports confirming the absence of damage to the fan blades. The fan impeller shall undergo a two-sided dynamic balancing test according to GB/T9101 {Dynamic Balancing of Fan Rotors}. The factory-outgoing dynamic imbalance grade must reach G5 or higher, exceeding the national standard requirements. Upon leaving the factory, users shall receive an impeller dynamic balancing test report. The paint coating on the external surface of the fan shall comply with the technical requirements specified in JB/T6886 {Technical Conditions for Fan Painting}. The fan nameplate shall be manufactured in accordance with the requirements of GB/T13306 {Nameplates}.

Main features of the fan

1. Impeller arrangement: A direct-drive structure is adopted, in which the impeller is fixed to the hub via a key connection through the shaft.

2. The fan’s key components include a variable-diameter connecting duct, a flow collector, an electrically actuated manual butterfly valve (including electric heating), a connecting duct, a primary-stage main unit, a secondary-stage main unit, an explosion-proof frequency converter motor, a diffuser, a round-to-square transition piece, a silencer, a diffusion tower, a braking device, and support rollers, among others.

3. The fan is equipped with a combined manual and automatic braking device that can achieve normal startup and reverse airflow within 5 minutes, with the reverse airflow rate exceeding 60% of the forward airflow rate.

4. During fan design, we optimize the selection based on the parameters provided by the user and carry out personalized design to ensure that the fan operates with high efficiency both in the initial and later stages.

5. The fan casing is fabricated by welding Q235 steel plates. At the factory, it is primed twice with epoxy zinc-rich primer and coated once with epoxy zinc topcoat. All bolts are galvanized.

6. The silencing perforated plates are all made of galvanized steel, effectively extending their service life and reducing subsequent replacement costs.

7. The host casing and the rotating parts of the impeller are equipped with protective rings. The protective cylinder is securely fastened to the copper ring using an explosive welding composite process, ensuring it remains firmly in place, safe, and reliable.

8. Differences in blade fixing methods:

The blades made of cast aluminum alloy are secured using a conical clamping method. Although the machining process is complex, this method ensures a firm and reliable fixation while remaining easy to operate. Improvement measures and the application of new technologies.

1. In the design of conventional motors, the cooling fan’s heat dissipation capacity (ventilation cross-section) is calculated based on natural ventilation conditions. However, when a fan motor is installed inside an isolation bearing housing, its ventilation conditions are significantly restricted. To address this issue of poor ventilation, our company has taken two key measures: First, we have increased the length of the isolation cavity (so that the airflow does not abruptly deflect by 90 degrees but flows smoothly through the cavity); and we have also expanded the ventilation cross-section of the fresh-air duct (typically to more than twice the cross-section of the motor itself). Second, we have independently designed an advanced front thermal channel for the motor (leveraging the superior design capabilities of our own engineering team), enabling airflow to enter from the intake port and smoothly exhaust the heated air from the motor through the exhaust port.

⒉ The use of a streamlined diffusion tower has resulted in a certain reduction in fan outlet noise and an efficiency improvement of 2–4%.
