DKT Cabinet External Extractor Blowers Inlet Centrifugal Fan

Product Applications:

• The Inlet Centrifugal Fan adopts a air intake design, enabling simultaneous airflow absorption . This structure enhances airflow efficiency and pressure output while balancing axial forces for reduced vibration and noise . Ideal for industrial applications requiring high airflow and medium-to-high pressure, such as HVAC systems, ventilation, and material handling.

Inlet Efficiency
Balanced axial force minimizes mechanical wear and extends operational stability.



Robust Construction
Impeller directly mounted on an outer rotor motor, eliminating secondary assembly errors and ensuring high structural integrity .


Energy-Saving Design
EC motors reduce energy consumption by 20–30% while supporting PWM/0-10V speed control for precise airflow adjustment .
Aerodynamically optimized blades lower noise levels (<65 dB) and improve efficiency

Applications

• Industrial Ventilation: Dust removal, boiler combustion air supply, and fume extraction
• HVAC Systems: Air conditioning, cooling towers, and humidity control units
• Material Handling: Pneumatic conveying of granular or powdered materials

Technical Advantages

• Wide Operating Range: Adjustable three-way valve design allows switching between single/double inlet modes, optimizing performance under varying flow demands
• Easy Maintenance: Accessible motor and impeller compartments simplify inspection and part replacement
• Certifications: Compliant with CE, CCC, and RoHS standards for safety and environmental protection

Ordering Information

• Standard models available for immediate shipment.
• Custom specifications (e.g., voltage, flange types, anti-static coatings) require a 15–30-day lead time.
