The oblique flow fan is a new type of low-noise, high-efficiency, energy-saving oblique flow ventilator with advantages such as low noise, low power consumption, and compact structure, and can be installed horizontally or vertically. It is widely used in the ventilation systems of industrial and civil buildings. The environment for the GXF oblique flow fan should be kept clean, with the fan surface being free of dirt, and no obstructions at the intake and exhaust air outlets. Dust and other debris inside the fan and pipelines should be removed regularly. If abnormal sounds, severe overheating of the motor, live casing, circuit breaker tripping, or inability to start are detected during the operation of the GXF oblique flow fan, the machine should be immediately stopped for inspection. For safety reasons, maintenance is not allowed during fan operation. After maintenance, the fan should be tested for about five minutes to ensure there are no abnormal phenomena before starting it up again.
