The FB3G355-2APK-30 is a heavy-duty backward centrifugal fan engineered for industrial ventilation systems that demand both massive airflow and exceptional static pressure capability. This 355 mm fan delivers a maximum airflow of 6182.2 m3/h and a static pressure of 1092 Pa, making it a true workhorse for high-resistance ducting and filtration setups. Its integrated BLDCEC137 motor operates on 230VAC (184~270V range) and consumes 880 W, offering a straightforward drop-in replacement for traditional AC fans with superior efficiency. The glass-fiber reinforced polypropylene impeller ensures lightweight construction with excellent chemical resistance and dimensional stability, ideal for corrosive air streams. With a speed of 2400 RPM and a noise rating of 89 dB(A), this fan balances performance with manageable acoustics for industrial environments. The die-cast aluminum endcaps and housing provide robust mechanical protection, while the 18AWG cable (1000mm) simplifies installation. Designed for OEM/ODM projects, this model meets diverse certification standards and suits applications like HVAC, cleanrooms, and process ventilation. Choose FANOVA for reliable, high-pressure air movement backed by expert engineering and customization options.
The FB3G355-2APK-30 represents a pinnacle of backward curved centrifugal fan technology, combining a 355 mm impeller with a high-efficiency BLDCEC137 motor to achieve a unique performance envelope. The impeller, constructed from polypropylene reinforced with glass fiber (PP+GF), features a backward-curved blade design that optimizes aerodynamic efficiency while minimizing turbulence and noise. This material choice offers a significant weight reduction compared to metal impellers, reducing bearing load and enabling smoother operation at high speeds up to 2400 RPM. The rotor diameter is 137 mm, paired with a direct-drive configuration that eliminates belt maintenance and enhances reliability. The motor is a brushless DC EC type, powered by 230VAC (184~270V range) with a maximum current draw of 3.8 A, delivering 880 W of shaft power. This EC technology provides built-in speed control via 0-10V or PWM signals, allowing precise modulation of airflow from 0 to 3638.2 CFM (6182.2 m3/h) and static pressure up to 4.37 in.wg (1092 Pa). The motor incorporates electronic commutation, which reduces energy consumption by up to 30% compared to standard AC motors, and features overcurrent, overvoltage, and thermal protection for safe operation in demanding conditions. The housing and endcaps are precision die-cast from aluminum alloy, offering high thermal conductivity and structural rigidity to withstand industrial vibration and thermal cycling. Bearing systems are sealed ball bearings with a rated life exceeding 40,000 hours at 60°C ambient temperature, ensuring long-term durability. Electrical connection is via an 18AWG cable with 1000mm length, terminated with flying leads for flexible integration into control panels. The fan is rated IP44 as standard, with optional IP55 upgrades for dusty or washdown environments. All components comply with CE, RoHS, and UL recognized standards, and FANOVA's ISO9001 production process ensures consistent quality. This model excels in applications requiring high static pressure, such as HEPA filtration, long duct runs, and multi-outlet distribution systems, making it a versatile core for OEM equipment manufacturers.

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 FB3G355-2APK-30 delivers 6182.2 m3/h at 1092 Pa while drawing only 880W, achieving 30-40% energy savings over equivalent AC fans through FANOVA's BLDC motor technology.
