DKT External Extractor Blowers Inlet Centrifugal Cabinet Fan

Product Overview

The Inlet Centrifugal Fan features an innovative air - intake configuration. It can absorb airflow simultaneously, which is a unique design element not commonly found in other fans. This design significantly enhances the airflow efficiency and pressure output. Additionally, it effectively balances axial forces, reducing both vibration and noise during operation.

Key Features

High - Efficiency Inlet Design

The balanced axial force design in this fan is a major advantage. It minimizes mechanical wear by ensuring that all parts of the fan operate under a more uniform stress distribution. As a result, it not only extends the fan's lifespan but also enhances its operational stability over the long term.

Sturdy Construction

In this centrifugal fan, the impeller is directly mounted on the outer rotor motor. This one - piece design eliminates the issues associated with secondary assembly, such as alignment errors and part mismatches. It guarantees a high level of structural integrity, making the fan more reliable in various working conditions.

Energy - Saving Capabilities

Equipped with EC motors, the fan achieves remarkable energy savings of 20 - 30%. These motors support PWM/0 - 10V speed control, allowing for precise adjustment of the airflow according to different requirements. The aerodynamically optimized blades further contribute to its performance. They not only reduce noise levels (below 65 dB) but also improve the overall efficiency of the fan.

Product Applications

• Industrial Ventilation: It is suitable for applications like dust removal in factories, air supply for boiler combustion, and extraction of fumes. In these scenarios, the fan effectively maintains a clean and safe working environment.
• HVAC Systems: Whether it is for air - conditioning units, cooling towers, or humidity control devices, the fan can meet the requirements of different HVAC applications, providing stable and efficient airflow regulation.
• Material Handling: In the process of pneumatically conveying granular or powdered materials, the fan can generate the necessary air pressure and airflow, ensuring smooth material transfer.

Technical Advantages

• Flexible Operating Range: The fan is equipped with an adjustable three - way valve. This unique design permits users to switch between single - inlet and double - inlet modes, enabling the fan to optimize its performance under different flow demands.
• Convenient Maintenance: Access to the motor and impeller compartments is straightforward. This simplifies the inspection process and makes part replacement quicker, reducing downtime in case of maintenance needs.
• Certifications: The fan complies with CE, CCC, and RoHS standards. These certifications confirm that the product is designed with safety and environmental protection in mind, ensuring its acceptability in both domestic and international markets.

Ordering Information

• Standard models are ready for immediate shipment, which is beneficial for customers with urgent needs.
• For custom - specified products, including different voltage requirements, various flange types, or anti - static coatings, there is a lead time of 15 - 30 days. This allows customers to get products tailored to their specific needs while planning their projects accordingly.
