To reduce the noise and vibration generated by the crossflow fan, you can choose the following methods:

1. Positioning and assembly: Ensure that the crossflow fan is installed in a firm position to prevent loosening or shaking. Use a suitable support frame or positioning device to firmly install the fan to the internal structure of the electric oven to reduce vibration and noise.

2. Isolation and shock absorption, use sound insulation and shock-absorbing materials to prevent vibration transmission between the fan and the electric oven. You can also add vibrationabsorbing pads or rubber pads between the contact area of the fan and the electric oven to reduce the transmission of vibration.

3. Reduce the fan load: Ensure that the fan load is effective and does not exceed its creative capacity. Excessive load may cause increased fan noise and vibration. According to the manufacturer's advice, ensure that the fan is used at its rated level.

4. Cleaning and maintenance: Clean and maintain the crossflow fan regularly, including removing dust and debris accumulation. Accumulated dust and debris may cause imbalance and increased noise. Follow the manufacturer's cleaning manual to clean and maintain the fan regularly.

5. Use noise reduction devices: Consider using specially designed noise reduction devices such as noise reduction pads, soundproofing covers or noise absorbing materials, and install them around the crossflow fan to reduce noise transmission and scattering.

6. Refer to the manufacturer's recommendations: Manufacturers generally provide specific recommendations for reducing noise and vibration. Check the user manual of the oven or fan, the manufacturer's website or contact the manufacturer's customer service to understand their recommendations.

By taking these measures, the noise and vibration generated by the crossflow fan can be reduced, improving application performance and indoor air quality.
