FW3G910-4APM-8M EC Axial Fan with Wall Ring, 400VAC 3-Phase, 910mm, 34577 m3/h

The FW3G910-4APM-8M is a massive 910mm 3-phase 400VAC EC axial fan with integrated wall ring, engineered for the largest industrial and agricultural ventilation applications. Powered by the BLEC188 brushless EC motor delivering 3000W at 1080 RPM, it generates an extraordinary 34,577 m³/h airflow — the highest capacity fan in the FANOVA product lineup. Operating on standard 3-phase 400VAC 50/60Hz industrial power, it draws just 4.5A per phase across a 380-480 VAC range, providing compatibility with electrical grids worldwide. The 910mm diameter swept area with wall ring mounting delivers maximum air exchange efficiency for large-scale ventilation. Features IP54-rated protection — significantly more robust than IP44 — providing dust-protected and splash-proof operation for demanding agricultural and industrial environments. The motor features Class F insulation for elevated temperature operation. With integrated FG tach output and compatibility with 0-10VDC/PWM control, it enables variable-speed operation for demand-based ventilation energy optimization. Ideal for large-scale agricultural greenhouse and livestock ventilation, industrial factory air exchange, warehouse ventilation, mining ventilation, and large DC/EC cooling wall applications. CE and RoHS certified.

At the core of the FW3G910-4APM-8M is the BLEC188 external rotor brushless EC motor — the most powerful motor in the FANOVA EC lineup at 3000W — directly driving a 910mm axial impeller at 1080 RPM. The massive 910mm swept area enables extraordinary airflow generation: 34,577 m³/h from a single fan, making it suitable for applications that would otherwise require multiple smaller fans. The BLEC188 motor operates directly from 3-phase 400VAC 50/60Hz mains (380-480 VAC range) without an external inverter or VFD, providing plug-and-play EC efficiency in industrial power environments. The aerodynamic axial design with integrated wall ring mounting optimizes airflow distribution while simplifying installation into wall openings. The motor draws 4.5A per phase at 3000W, achieving 75-80% efficiency — representing 30-40% energy savings versus equivalent 3-phase AC induction motor fans. Variable-speed control via 0-10VDC analog or PWM digital input enables demand-based ventilation strategies, with FG tachometer feedback for closed-loop integration with climate control and building management systems. Built-in protection includes soft-start, current limiting, locked-rotor protection, over/under-voltage protection, phase-loss detection, and electronic thermal overload protection. The fan features IP54-rated dust-protected and splash-proof construction, Class F insulation for continuous operation at elevated temperatures, heavy-duty ball bearings, and a die-cast aluminum housing engineered for 50,000-hour L10 lifespan under continuous industrial duty.

I. When taking out the fan, do not directly lift the fan lead wire. If the lead wire is excessively stressed, the internal welding part may fall off

II. Do not plug or unplug the fan lead plug when the fan is running

III. If the fan does not work after starting, do not touch the impeller, rotor, or other parts, professional technical personnel are required to inspect the fan to prevent sudden start of the fan from causing hand or other personal injury

IV. Because of the soft start characteristics of the fan, to prevent personal injury, do not touch the impeller or other parts of the fan during powered on or running at low speeds

V. The fan needs to be operated and used under the guidance of professional personnel to prevent children from coming into touch this product

VI. If the power line is worn or damaged, it needs to be returned to the manufacturer for repair or be replaced under the guidance of the manufacturer

VII. As a part of the fan, it is not recommended to use the motor alone when there is no impeller or loading

1. Massive 34,577 m³/h Airflow: The FW3G910-4APM-8M delivers an extraordinary 34,577 m³/h — the highest capacity in the FANOVA lineup — from a single 910mm axial fan. One unit replaces multiple smaller fans, simplifying installation and reducing system complexity for large-scale ventilation projects.

2. 3-Phase 400VAC Industrial EC Power: The 3000W BLEC188 motor operates directly from standard 3-phase 400VAC 50/60Hz mains — no VFD, inverter, or transformer required. 75-80% EC efficiency delivers 30-40% energy savings versus equivalent 3-phase AC induction motor fans.

3. IP54 + Class F for Harsh Environments: Dust-protected and splash-proof IP54 construction with Class F insulation enables reliable operation in agricultural (greenhouse, livestock), industrial (factory, warehouse), and outdoor applications where dust, humidity, and elevated temperatures are present.

4. Large-Scale Industrial & Agricultural Applications: Purpose-built for agricultural greenhouse ventilation, livestock barn air exchange, industrial factory cooling, warehouse ventilation, mining air supply, and large-scale DC cooling walls. OEM/ODM available.

5. Variable-Speed Energy Optimization: 0-10VDC/PWM control plus FG tach feedback for precision climate control integration. Demand-based speed regulation maximizes energy savings during partial-load conditions. 3-year warranty.
