CDZ Series Ultra-Low-Noise Axial Fans

Applications

In addition to the features of the T35-11 axial fan, this fan uses a wide-chord, forward-swept blade design with equal blade spacing. This reduces airflow separation over the blade surfaces and the formation of vortices, lowering secondary airflow losses inside the fan and reducing aerodynamic noise from the air source. The airflow is stable. Tests on the prototype confirmed that the fan meets the national ultra-low-noise standard. Its airflow, pressure, and noise performance are among the best in China for comparable products. It offers significant social and economic benefits by protecting the environment and saving energy.

Structural Features

CDZ series ultra-low-noise axial fans are made entirely of high-quality steel. They are available in three configurations: duct-mounted, fixed, and rotating. They are widely used for ventilation in industrial and mining enterprises, workshops, warehouses, laboratories, office buildings, sports venues, hotels, restaurants, and other civil buildings. They can also be connected in series or in parallel in duct systems to increase pressure or airflow for exhaust or supply ventilation. These fans are suitable for conveying non-flammable, non-corrosive gases containing no significant dust. The gas temperature must not exceed 40℃.
