Overview

The FNT Series is a line of high-performance centrifugal fans powered by advanced EC (Electronically Commutated) external DC brushless motors. These fans are engineered for applications requiring high static pressure, reaching up to 1600 Pa, and significant airflow capacities. Featuring backward-curved aluminum airfoil impellers, the FNT series offers a superior combination of energy efficiency, intelligent control, and quiet operation in a compact design.


Key Features


  • Smart Control: Integrated electronics allow for precise speed regulation via 0-10VDC or Modbus signals.
  • EC Motor Technology: High-efficiency brushless motors reduce energy consumption and heat generation compared to traditional AC motors.
  • Backward-Curved Impeller: Constructed from high-strength aluminum, the airfoil blades are designed for non-overloading characteristics and high static efficiency.
  • Robust Design: Designed to operate in a wide temperature range, typically from -25°C to +60°C depending on the specific model.
