1. The side wall is directly driven by the motor, the leaf is presented, the low noise exterior or inner rotor, the square shell design, can be easily installed on the concrete wall, brick wall or light steel alien wall plate.The square rainproof cover structure is strong and beautiful.It has the characteristics of low noise, large air volume, reliable operation, wide range of performance parameters, and simple installation.It is widely used in the side wall ventilation of factories, mines and civilian commercial buildings.According to the requirements of the conveying medium, the anticorrosive explosion -proof type can be made.2. The side wall uses a low noise shaft impeller, a direct drive of the motor, and a square muffler shell (can further reduce the noise; make the whole machine into a square shape, and the square holes on the wall are simple and easy to install).The outlet is equipped with aluminum alloy self -hanging shutters (can prevent outdoor rain, dust, natural wind return indoors); 3. It has significant advantages such as beautiful appearance, low noise, stable operation, and firm installation.Widely used in the low -noise wall exhaust of civil commercial construction engineering and factory and mines.According to the application requirements, explosion -proof and anti -corrosion can be made.The side wall is directly driven by the motor, the leaf is plundered, the low noise exterior or inner rotor is designed, and the square shell is designed, which can be easily installed on the concrete wall, brick wall or light steel alien wall plate.The square rainproof cover structure is strong and beautiful.The side wall has the characteristics of low noise, large air volume, reliable operation, wide range of performance parameters, and simple installation.It is widely used for side walls of factories, mines and civilian commercial buildings.4. According to the requirements of the conveying medium, it can be made into anticorrosive explosion -proof type.The side wall is generally used for side wall exhaust, equipped with a 45 rain cover (or special 60) and insect -proof network (which can prevent insects from flying into the workshop at night).The side wall fan can be made into DWSP (WSP) as needed, equipped with a 90 rain cover (windproof, rainproof and dustproof) and insect -proof nets (preventing insects from flying into the workshop at night).5. The side wall adopts a high -tech front plunder wheel.The blade line gradually cut into the air, and the leaves are smooth.When they are separated from the air, the tilt angle of the outer edge of the blades reduces separation turbulence, so as to ensure low noise and large exhaust volume.During the design process, a sufficient stress analysis was performed.6. Strengthen the end of the end of the leaves to prevent the leaves from deforming and broken leaves.Low noise exterior rotor or internal rotor motor is directly driven, effectively reducing the impact of noise on the surrounding environment.The square shell is designed and installed on the concrete wall, brick wall or light steel alien wall, with a strong structure and a beautiful appearance.7. The side wall has the characteristics of low noise, large air volume, reliable operation, wide range of performance parameters, and simple installation.The performance of the present invention is stable and reliable, reduced the transmission loss, and reduces the weight of the machine.Because the motor is directly placed in the airflow, it can ensure good heat dissipation and extend the service life of the motor.The protection level is IP54, the insulation level is F, and the insulation level is B. The motor should be located in the airflow and can cool the motor. In this way, the side wall fan electrical opportunity is short -circuit due to high temperature.The aluminum plate has a clear and distinguished fan number, model and product name, rotation direction, airflow direction, etc.It can ensure the production date and history of the customers convenient query accessories, and provide conditions for maintenance.
The above is the characteristic of the wall fan
