Quiet Cooling Solution for Sensitive Electronic Equipment

SZR's Low Noise DC axial fan series is designed for applications requiring stable ventilation with minimized acoustic interference. The fan structure balances airflow efficiency and quiet operation, making it suitable for electronic systems operating in noise-sensitive environments.

Acoustic Optimization

The fan blade profile is engineered to reduce airflow turbulence and lower operational sound levels during continuous rotation.

Compared with conventional cooling fans, the optimized motor and blade coordination decreases vibration transmission while maintaining effective airflow circulation. The brushless DC motor structure supports smooth startup performance and stable low-noise operation.

12V and 24V DC input options support compatibility with various electronic cooling systems.

Product Structure

The lightweight fan frame uses high-strength thermoplastic material resistant to thermal deformation and environmental stress.

Precision-balanced impeller construction improves rotational smoothness and reduces mechanical vibration during operation. Integrated bearing technology extends service life and enhances operational consistency.

Optional anti-vibration pads and PWM speed control functions are available for advanced noise reduction requirements.
