FW3G250-2APD-70 Axial Fan, 230VAC, 250mm, 1220.3 m3/h

When your ventilation system must disappear into the background—both acoustically and electrically—the FW3G250-2APD-70 axial fan from FANOVA delivers the quiet, efficient performance that modern building and equipment designers demand. Operating on a standard 230VAC supply with a wide 184–277V input range, this fan's EC motor sips just 28.5W at full speed, making it an exceptionally low-energy solution for continuous-duty applications. Its 250mm impeller, molded from glass-fiber-reinforced polypropylene, generates an impressive airflow of up to 1220.3 m3/h while producing only 48.2 dB(A) of noise—quieter than a normal conversation. This combination of ultra-quiet operation and low power consumption makes it ideal for hospitals, laboratories, offices, and other noise-sensitive environments where long-running fans must not disturb occupants. The die-cast aluminum housing ensures robust mechanical integrity and effective heat dissipation, while the 20AWG cable simplifies installation. With variable speed control capability via 0-10V DC or PWM signals (depending on the controller), the fan can be precisely tuned to match system requirements, further reducing energy use. Certified to CE and RoHS standards, the FW3G250-2APD-70 is a drop-in upgrade for existing AC fans, offering superior efficiency and a longer service life. Choose FANOVA for reliable, quiet, and eco-friendly airflow solutions.

The FW3G250-2APD-70 is a 230VAC axial fan that exemplifies the next generation of energy-efficient ventilation technology. At its heart lies a brushless DC (BLDC) motor with an integrated EC (Electronically Commutated) controller, which delivers high efficiency across the entire speed range. The motor operates on a universal input voltage of 184–277VAC, making it suitable for both 230V and 277V electrical systems without the need for external transformers. At the rated 1500 RPM, the fan draws just 28.5W and 0.25A, consuming up to 70% less energy than a comparable shaded-pole or permanent split capacitor motor. This extraordinary efficiency not only reduces operating costs but also minimizes heat generation, extending the life of the motor and its components.

The impeller is crafted from polypropylene reinforced with glass fibers, a material chosen for its excellent strength-to-weight ratio, chemical resistance, and dimensional stability. The 250mm diameter impeller features an aerodynamically optimized blade profile that maximizes airflow while minimizing turbulence and noise. The fan achieves a maximum airflow of 1220.3 m3/h (718.1 CFM) and a maximum static pressure of 105 Pa (0.42 in.wg), allowing it to overcome the resistance of ductwork and filters in typical HVAC applications. The low noise figure of 48.2 dB(A) ensures that this fan operates well below the threshold of conversational speech, making it an unobtrusive choice for acoustic-sensitive spaces.

Speed control is handled by the EC controller, which accepts external control signals via a dedicated interface. The fan supports 0-10V DC analog control as well as PWM (pulse width modulation) input, allowing seamless integration with building management systems (BMS) or simple wall-mounted speed controllers. This flexibility enables the fan to modulate its speed in response to system demands, reducing energy consumption further and improving occupant comfort. The motor is fully protected against overcurrent, overvoltage, and overheating, ensuring reliable operation in demanding environments. Its insulation system meets Class B requirements, and the motor is rated for continuous operation at ambient temperatures up to 60°C.

The fan's end housing and impeller hub are manufactured from die-cast aluminum, providing a sturdy, corrosion-resistant frame that withstands mechanical stress and dissipates heat effectively. The rotor diameter is 72mm, and the entire assembly is balanced to G2.5 quality, ensuring vibration-free operation. The fan is equipped with a 20AWG lead wire for power and control connections; the cable length and connector options can be customized to suit OEM requirements. With a lifespan exceeding 50,000 hours under normal operating conditions, the FW3G250-2APD-70 is designed for long-term reliability. The product is CE and RoHS certified, and FANOVA's manufacturing facility is ISO9001 and ISO14001 certified, guaranteeing consistent quality and environmental responsibility. Whether used in fresh air ventilation units, heat recovery ventilators, air handling units, or industrial equipment, this fan offers a perfect balance of performance, efficiency, and acoustic comfort.

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.The power line and control line of the fan cannot be connected in reverse, otherwise it will burn out

Ⅴ.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

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

Ⅶ.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

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

1. High Efficiency: The FW3G250-2APD-70 delivers 1220.3 m3/h at 105 Pa while drawing only 28.5W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 250mm galvanized steel sheet impeller resists corrosion, wear and high temperatures, making the fan suitable for harsh industrial environments and corrosive gas streams.
