Product Overview

Engineered by Fanova (Suzhou) Motor Technology, this high-performance backward-curved centrifugal fan combines robust industrial design with intelligent control. Built for demanding ventilation applications, it features an external rotor BLDC motor (Model BLEC102), a 280mm aluminum impeller, and delivers exceptional airflow (up to 3780 m³/h) and static pressure (1100 Pa). With IP54 protection, wide voltage compatibility (184–270 VAC), and support for multiple control protocols, it excels in environments requiring reliability, efficiency, and adaptability.


Core Features

  1. High-Efficiency Airflow & Pressure Performance
    Optimized 8-blade aluminum impeller generates 3780 m³/h max airflow and 1100 Pa max static pressure at 3270 RPM. Ideal for overcoming system resistance in ducted HVAC, industrial exhaust, or air-handling units.

  2. Smart Control & Protection Suite
    Supports 0–10VDC/PWM speed control and RS485 (MODBUS) for seamless integration. Built-in protections include soft-start, over/under-voltage lockout, motor temperature monitoring, and reverse-polarity safety.

  3. Industrial-Grade Durability
    Operates reliably from -25°C to 60°C with ball bearings rated for 50,000 hours (L10). IP54 rating ensures dust/water resistance, while die-cast aluminum housing withstands mechanical stress.

  4. Flexible Installation & Compliance
    Mounts in any orientation with universal voltage compatibility (50/60 Hz). Certified for CE, RoHS, ISO9001, and ErP 2015, meeting EU and Chinese industrial safety standards.


Applications

  • HVAC Systems: Energy-efficient air circulation in commercial buildings.

  • Industrial Ventilation: Fume extraction, machinery cooling, or dust collection.

  • Air Purification Units: High-static-pressure support for HEPA filter systems.

  • Process Equipment: Thermal management in ovens, dryers, or industrial printers.


FAQ

Q1: Can this fan be controlled via building automation systems?
Yes. It accepts 0–10VDC analog signals, PWM input, or RS485 MODBUS communication for centralized control.

Q2: What happens if the voltage drops below 184VAC?
The fan’s under-voltage protection will safely shut it down to prevent damage, restarting automatically when voltage stabilizes.

Q3: Is it suitable for outdoor/condensing environments?
Yes. IP54 protection and -25°C cold-start capability make it resilient in damp or variable-temperature settings.
