Product Overview

The 230V-AC 310mm 500W Backward-Curve Centrifugal Fan delivers industrial-grade static pressure for demanding ventilation systems, powered by an external-rotor EC motor (Model: BLEC102) and a 7-blade glass-fiber reinforced polypropylene impeller. Engineered to generate 950 Pa maximum static pressure at 3,721 m³/h airflow, it excels in high-resistance applications such as industrial dust collection or multi-stage filtration. With wide voltage compatibility (184–270V AC) and integrated control interfaces, it adapts to unstable grid conditions or automated building management networks.


Core Features

  1. High Static Pressure Performance

    • Generates 950 Pa peak static pressure – capable of overcoming resistance in long duct runs, HEPA filters (MERV 16+), or industrial dust collectors.

    • Radial blade design optimizes airflow efficiency across operating ranges (0–100% via PWM/0-10VDC control).

  2. Precision Control & Monitoring

    • 0–10VDC/PWM Speed Input: Enables dynamic airflow adjustment for energy-efficient operation.

    • +10VDC Output: Provides reference voltage for external sensors or tachometer signals (FG output: 5 pulses/revolution).

    • RS485 Modbus Interface (RSA/RSB terminals): Supports integration with industrial automation systems.

  3. Robust Industrial Protection

    • Soft-start protection to limit inrush current

    • Overvoltage/undervoltage cutoff (184–270V AC)

    • Electronics and motor thermal overload protection.

    • IP54-Rated Housing: Sealed against dust ingress and water splashes for harsh environments.

    • Multi-Stage Safeguards:

    • Ball Bearings & Reinforced Impeller: Ensure continuous operation (S1 duty) from –25°C to 60°C.

  4. Optimized Acoustic Profile

    • Operates at 81 dB(A) under full load – engineered for industrial noise standards despite high-power output.

    • Electromagnetic Shielding: Encapsulated windings reduce interference in sensitive electronic environments.


Typical Applications

  • Industrial Dust Extraction: Primary fans for woodworking, metal grinding, or powder handling systems.

  • Large-Scale HVAC: High-pressure units in commercial air handlers or cleanroom ventilation.

  • Process Cooling: Forced airflow for industrial ovens, kilns, or laser cutting machinery.

  • Energy Recovery Systems: Boosters in heat-reclaiming ventilation units with dense heat exchangers.
