QDBF ​Centrifugal Fan with External Rotor

The QDBF series centrifugal fan is designed with an external rotor, double inlet, removable full metal frame, and insulated sound absorbing panels. This air moving equipment is extremely convenient and flexible when it comes to installation. The horizontal type centrifugal fan is designed with a horizontal inlet and outlet while the vertical type centrifugal fan features a horizontal inlet and vertical outlet. This centrifugal fan is suitable for handling air that is non-corrosive, nonflammable, non-explosive, and where dust concentration is no more than 100mg/m3. The fan is able to withstand a working temperature range from -20℃ to 80℃. Widely used for air supply and exhaust for air conditioning systems, the centrifugal fan is often applied in factories, residential buildings, hotels, malls, hospitals, and many other environments.

Features The centrifugal fan is designed with an external rotor and double inlet. It features a compact structure with powerful ventilation efficiency, high airflow, high pressure, smooth running, and low noise. Air volume can be adjusted to meet different environmental conditions. This helps you minimize energy consumption when air flow demands are not as high. It can supply air to multiple ductworks with different orientations simultaneously. This series of centrifugal fan provides 102 different specifications for you to choose from. Its air volume and pressure can be modified by power regulation or power frequency conversion according to your requirements. An electric control box is optional and enables remote control functionality. Dimensions Specifications
