The DWT Series Low-Noise Roof Ventilator is engineered for reliable, quiet, and efficient air movement in diverse industrial and commercial settings. Constructed from high-quality materials such as galvanized powder-coated steel, engineering plastics, FRP, and aluminum alloy, these fans are lightweight yet highly resistant to corrosion, flame, and explosion. Featuring a streamlined design with an imported gel-coat resin finish, they ensure both superior performance and an aesthetically pleasing appearance.

Structure & Components

Each DWT roof ventilator consists of a motor, impeller, air duct, wind cap, transmission assembly, louver damper, bird screen, and safety guard. Models up to size 11.2# employ a direct motor drive, while size 12# and above utilize belt drive or reducer drive systems for enhanced power and flexibility. Louver dampers are available in gravity-operated, manual, or electric types to meet various control needs. For ease of maintenance, models size 12# and above include an access door, while smaller models feature a removable wind cap.

These axial-flow fans are designed with the impeller mounted directly on the motor shaft, secured by keys, pressure plates, and bolts. The motor is efficiently cooled by integrated radiator fins on the base and the axial airflow generated during operation.

Applications & Versatility

The DWT Series is widely used across pharmaceuticals, chemicals, textiles, food processing, metallurgy, power generation, and various industrial or civil buildings as part of ventilation and air-conditioning systems.

• DWT (Ⅰ) Axial-Flow Roof Fans are ideal for applications requiring high air volume.

• DWT (Ⅱ, Ⅲ) Centrifugal Roof Fans deliver higher pressure performance for more demanding ventilation scenarios.
