CDC-E Series Silent Fan

Summary：
CDC-E series silent fan adopts advanced EC technology motors and an integrated control system that enables stepless speed regulation. It is equipped with a double-inlet forward-curved impeller and a high-efficiency soundproof outer casing. This series features high efficiency, low noise, excellent performance, compact structure, and easy installation. 
CDC-E series silent fans come in four sizes: 200, 230, 315, and 335. Airflow: 2000-6000 m³/h, Total pressure: 230-630 Pa.
The fan has a simple and elegant appearance, making it widely used in ventilation and air exchange for buildings such as hospitals, schools, enterprises, hotels, and conference rooms.

Advantages：
1.High Efficiency: Compared to traditional motors, EC motors can achieve an efficiency of over 90%, saving up to 50% in energy consumption, thereby reducing the operating costs for users.
2.Compact Size: Since EC motors no longer require commutators and carbon brushes, the motor size is significantly reduced, resulting in a more compact fan structure. This minimizes installation space, making it suitable for applications where space is limited.
3.Low Noise: The box structure reduces noise, sound-absorbing materials further decrease noise, optimized airflow paths minimize noise, and the low-noise EC motor contributes to a quieter operation.
4.Real-time Speed Control: The EC motor, through its integrated control system, achieves stepless speed regulation, adjusting according to the working environment. This ensures smooth operation and a long service life.
5.Easy Maintenance: The direct-coupled drive of the motor simplifies maintenance. The inspection panel is easy to install and remove, making maintenance operations convenient and straightforward.
6.Durable and Aesthetic: The entire outer casing of the unit is treated with high-quality galvanized metal, providing resistance to moisture, corrosion, rust, and fire, ensuring both durability and an attractive appearance.
