FK3G250-2AAF-6B Plug Fan, 230VAC, 250mm, 2930.3 m3/h

The FK3G250-2AAF-6B plug fan is engineered to replace multiple smaller fans in high-demand ventilation systems, delivering a massive 2930.3 m3/h airflow from a single 280 mm die-cast aluminum impeller. This 230VAC EC fan operates across a wide 184~270V input range, making it a true plug-and-play upgrade for existing AC installations. With a maximum static pressure of 1412 Pa, it effortlessly overcomes high-resistance ductwork, HEPA filters, and multiple outlet branches without sacrificing performance. The integrated BLDCEC102 motor consumes only 870 W at 4100 RPM, achieving energy savings of up to 50% compared to conventional AC plug fans under similar duty. Its die-cast aluminum construction ensures exceptional rigidity and thermal conductivity, prolonging bearing life even in continuous industrial operation. The fan includes an 18AWG cable (253 mm) and is designed for straightforward electrical integration with standard 230VAC supplies. Ideal for HVAC units, cleanroom equipment, and industrial process ventilation, this model meets rigorous performance and reliability standards. Each unit is factory-balanced and tested to deliver consistent, low-noise operation at 84 dB(A) while maintaining high volumetric efficiency. FANOVA's OEM/ODM flexibility allows customization of speed control interfaces, connectors, and packaging to match your exact system requirements. Choose the FK3G250-2AAF-6B to consolidate your fan count and simplify your BOM while boosting airflow and static pressure capabilities.

The FK3G250-2AAF-6B is a backward-curved centrifugal plug fan that combines a large 280 mm impeller with a high-efficiency BLDC EC motor to deliver industry-leading airflow and pressure in a compact plug-fan format. The impeller is precision die-cast from aluminum alloy, featuring a backward-curved blade geometry optimized for low turbulence and high aerodynamic efficiency. This construction minimizes noise generation while maximizing pressure build-up, making the fan suitable for systems that demand 1412 Pa of static pressure, such as multi-stage filtration units or long-span duct networks. The housing endcaps are also fabricated from die-cast aluminum, providing robust mechanical support and superior heat dissipation for the motor and bearings.

The motor technology is based on FANOVA's BLDCEC102 platform, a brushless DC motor with an integrated electronic commutation controller. Operating on a nominal 230VAC supply, the motor accepts a wide input range of 184 to 270VAC, ensuring stable operation under fluctuating grid conditions. The EC design allows for infinitely variable speed control via 0-10V DC or PWM signals, facilitating precise airflow modulation to match real-time demand. At full speed (4100 RPM), the fan draws 4.0 A and consumes 870 W of electrical power, delivering a maximum airflow of 1724.5 CFM (2930.3 m3/h). The motor's high power density enables this output while maintaining an efficiency level that reduces energy consumption by up to 50% relative to traditional shaded-pole or capacitor-run AC motors of equivalent size.

Electrical ratings include a current draw of 4.0 A at nominal voltage, with the motor protected against overcurrent, overvoltage, and overtemperature via internal electronic safeguards. The insulation system meets Class B standards, and the motor winding is designed for continuous duty in ambient temperatures up to 60 °C. The integrated electronics are potted to resist moisture and vibration, enhancing long-term reliability in harsh industrial environments. The fan uses a permanently lubricated, sealed ball bearing system that provides an L10 life of over 60,000 hours at rated conditions, ensuring maintenance-free operation for years.

Mechanical integration is simplified through a standard plug-fan flange layout, allowing direct mounting into equipment housings or duct plenums. The unit is balanced to ISO 1940 G2.5 grade, which minimizes vibration and reduces stress on downstream components. The electrical interface consists of an 18AWG lead cable with a length of 253 mm, terminated with bare tinned ends for flexible connection to terminal blocks or custom connectors. The cable is rated for 300V and is resistant to oil and mild chemicals, suitable for most HVAC and industrial applications.

The fan is manufactured under FANOVA's ISO 9001 quality management system, with each unit undergoing a 100% run-in test to verify electrical parameters, vibration levels, and noise output. The product is compliant with CE and RoHS directives, and the aluminum components are fully recyclable, supporting sustainability initiatives. For OEM clients, FANOVA offers customization options including alternative cable lengths, specialized connectors, conformal coating for corrosive atmospheres, and factory-programmed speed curves to match specific control systems. The FK3G250-2AAF-6B is the ideal choice for system designers seeking to consolidate fan count, reduce energy costs, and achieve reliable high-pressure performance in a single, compact unit.

AC Plug Fan
Type	FK3G250-2AAF-6B
Model	BLDCEC102

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
