FK3G280-2AAB-67 Plug Fan, 230VAC, 280mm, 3656.1 m3/h

The FK3G280-2AAB-67 is a high-performance plug fan engineered to deliver exceptional airflow and static pressure in a single, compact unit, eliminating the need for multiple smaller fans in demanding HVAC systems. With a maximum airflow of 3656.1 m³/h and a static pressure of 1158 Pa, this backward centrifugal fan tackles long duct runs, high-resistance filters, and multi-outlet distribution with ease. Powered by a 230VAC EC motor (BLDCEC102) that operates across a wide 184–270V range, it draws only 3.4A and consumes 700W, offering superior energy efficiency compared to traditional AC fans. The die-cast aluminum impeller (280mm diameter) and housing ensure robust durability and corrosion resistance, ideal for industrial environments. This plug fan is speed-controllable via 0-10V or PWM signals, allowing precise airflow modulation to match real-time demand. It features thermal protection, IP55-rated construction, and Class B insulation, ensuring safe operation in harsh conditions. The sealed ball bearings provide a lifespan of over 50,000 hours, minimizing maintenance downtime. Suitable for AHU retrofit, cleanroom filtration, and industrial ventilation, the FK3G280-2AAB-67 is a reliable, plug-and-play upgrade for AC-driven systems. Certified to CE and RoHS, this FANOVA model delivers peak performance with low noise at 82.5 dB(A) while maximizing energy savings.

The FK3G280-2AAB-67 is a state-of-the-art backward curved centrifugal plug fan designed to meet the rigorous demands of modern HVAC and industrial ventilation systems. Its impeller, constructed from high-grade die-cast aluminum alloy, features a 280mm diameter and optimized blade geometry that maximizes aerodynamic efficiency, achieving a peak airflow of 2151.6 CFM (3656.1 m³/h) and a maximum static pressure of 4.63 In.wg (1158 Pa). This combination of high flow and high pressure makes it exceptionally suited for applications requiring long duct runs, high-resistance HEPA filtration, or multiple supply outlets, where it can replace several smaller fans, simplifying system design and reducing footprint. The motor is a BLDCEC102 brushless DC electronically commutated type, operating on a 230VAC single-phase supply with a wide input voltage tolerance of 184–270V, ensuring stable performance under fluctuating grid conditions. It draws a rated current of 3.4A and consumes 700W, delivering a power output that drives the impeller to a maximum speed of 3270 RPM. The EC motor technology provides high efficiency across the entire speed range, with energy savings of up to 50% compared to conventional AC motors, and enables infinitely variable speed control through external 0-10V analog or PWM digital signals, allowing seamless integration with building management systems (BMS) for demand-based ventilation. For enhanced operational safety, the fan incorporates thermal overload protection and features an IP55-rated housing that shields internal components from dust and water jets, making it suitable for outdoor or washdown environments. The motor windings are insulated to Class B standards, capable of withstanding temperatures up to 130°C, while the double-sealed ball bearings offer a rated life of 50,000 hours at 70°C, ensuring long-term reliability. The electrical interface consists of an 18AWG cable with a length of 274mm, providing flexible wiring options in tight enclosures. The entire assembly, including the fan housing and endcaps, is manufactured from die-cast aluminum alloy, which offers excellent thermal conductivity, corrosion resistance, and structural integrity, reducing weight while ensuring durability. The fan operates with a noise level of 82.5 dB(A) at maximum speed, which is acceptable for industrial settings, but can be significantly reduced when operating at lower speeds. Certified to CE and RoHS, the FK3G280-2AAB-67 meets stringent European safety and environmental standards, and is backed by FANOVA's rigorous quality control procedures, ensuring consistent performance and a long service life. This plug fan is the ideal choice for OEMs seeking a high-pressure, high-flow, energy-efficient solution for AHUs, cleanrooms, and industrial process ventilation.

AC Plug Fan
Type	FK3G280-2AAB-67
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

1. High Efficiency: The FK3G280-2AAB-67 delivers 3656.1 m3/h at 1158 Pa while drawing only 700W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.

2. Industrial-Grade Impeller: The 280mm galvanized steel sheet impeller resists corrosion, wear and high temperatures, making the fan suitable for harsh industrial environments and corrosive gas streams.

3. Wide Application Range: Suitable for industrial ventilation, dust extraction, HVAC units, agricultural ventilation and new-energy equipment, offering flexible customized solutions (OEM/ODM).

4. Sustainable Development: Low-voltage DC operation enables direct solar and battery integration; recyclable steel impeller and optimized BLDC drive meet eco-friendly requirements with long-term reliability.

5. Easy Installation and Maintenance: Compact 280mm footprint, 0-10VDC/PWM speed control, FG tach output and standard cable make the fan simple to wire, control and service.
