FW3G350-2APC-20圆形导风筒
Fanova
The FW3G350-2APC-20 EC Axial Fan from Fanova (Suzhou) Motor Technology is an industrial-grade ventilation solution engineered for high-performance airflow demands in large buildings and commercial HVAC systems. Equipped with a brushless energy-efficient EC motor (Model: BLEC102) and a 350mm glass-fiber-reinforced propylene impeller, this fan delivers an impressive maximum airflow of 4650 m³/h (2736.525 CFM) and a static pressure of 275 Pa (1.1 In.wg), ensuring reliable ventilation even in complex ducting systems. With an IP54 protection level, it withstands harsh industrial and commercial environments, while its energy-saving design reduces consumption by up to 30% compared to traditional AC fans. Compliant with CE, RoHS, and ISO 9001 standards, this axial fan is a trusted choice for demanding ventilation applications requiring durability, efficiency, and smart control.

The fan’s core is a brushless EC motor with integrated soft-start protection, thermal overload safeguards, and reverse polarity protection. Operating across a wide voltage range (184–270 VAC), it maintains efficiency in fluctuating power grids, cutting energy costs by 30% versus conventional AC motors. The motor’s design ensures smooth, low-noise operation, making it suitable for noise-sensitive commercial spaces.
For seamless integration into automated systems, the fan supports 0–10VDC, PWM, and RS485 (Modbus) control inputs. The FG (tachometer) signal provides real-time RPM monitoring, while a +10VDC output enables daisy-chaining of multiple fans for centralized control—ideal for large building HVAC networks.
Constructed with a die-cast aluminum alloy motor housing and fiberglass-reinforced propylene impeller, the fan offers exceptional resistance to corrosion, impact, and wear. Rated for continuous S1 duty operation at temperatures from -25℃ to 60℃, it features ball bearings with a 50,000-hour (L10) lifespan (tested at 40℃, 15%–65% RH), ensuring long-term reliability in heavy-duty applications.
Meeting global safety standards (CE, RoHS, ISO 9001), the fan includes multi-layer protections: over/under-voltage detection, locked-rotor protection, and thermal overload safeguards for both the motor and electronics. Dual alarm contacts alert operators to system faults, minimizing downtime and maintenance risks.
Designed for high-static-pressure ventilation in commercial ducting, the fan efficiently circulates air in shopping malls, office towers, and industrial facilities, complementing central air conditioning systems to enhance indoor air quality.
Ideal for cooling electronics enclosures, CNC equipment, and process machinery, the fan’s high airflow rate dissipates heat quickly, protecting sensitive components from overheating and extending equipment lifespan.
In server rooms and data centers, the fan supports hot-aisle containment and rack cooling, maintaining optimal operating temperatures for servers and IT infrastructure with consistent airflow and quiet performance.
Suitable for greenhouse climate control and livestock barn ventilation, the fan’s durable design withstands humid agricultural environments, promoting healthy plant growth and animal welfare through consistent air circulation.
Yes, the fan supports any installation orientation (horizontal, vertical, or angled) without compromising performance. Its robust construction and balanced impeller ensure stable operation regardless of mounting position, making it flexible for diverse HVAC layouts.
Reverse connection of power (L/N/PE) or control wires (PWM/FG/RS485) may damage the fan’s electronics. Always follow the wiring diagram (Section 4 of the user manual) and separate strong-current and low-current wires to avoid short circuits or component failure. The fan’s reverse polarity protection minimizes risks but does not eliminate them—proper wiring is critical.
This is a normal feature of the soft-start protection system, which prevents inrush current from damaging the motor. Allow 2–3 seconds for initialization; do not touch the impeller during startup. If the fan fails to start after this period, check the power supply, wiring, and locked-rotor protection status.
