FB3G400-2APK-20
Fanova
The FB3G400-2APK-20 EC Backward Centrifugal Fan is a high-efficiency ventilation solution from Fanova, tailored for climate regulation in food cold storage systems and industrial applications. Powered by a 230VAC brushless EC motor, this fan delivers a maximum airflow of 5755 m³/h (3386.82 CFM) and an impressive static pressure of 785 Pa (3.14 In.wg), making it ideal for low-temperature, high-humidity environments. Featuring a galvanized steel sheet impeller (or glass-fiber-reinforced plastic option) and die-cast aluminum housing, it combines durability with energy efficiency—reducing power consumption by 30% compared to traditional centrifugal fans. With IP54 protection and compliance with CE, RoHS, ISO 9001, and ErP 2015 standards, it ensures reliable performance in food cold storage, factory ventilation, and commercial HVAC systems.

The fan’s BLEC102 brushless EC motor optimizes energy use, operating at a maximum 500W while delivering superior airflow and static pressure. Its wide voltage range (184–270 VAC) ensures stability in fluctuating power grids, making it perfect for remote or industrial locations. Compared to standard AC centrifugal fans, it cuts energy costs by 30%—a critical advantage for 24/7 operations like food cold storage.
Available with a galvanized steel sheet impeller or glass-fiber-reinforced plastic (GFRP) option, the fan is engineered for harsh environments. The GFRP impeller offers exceptional corrosion resistance, ideal for humid cold storage or chemical-rich factory settings, while reducing inertia for faster response times and lower wear on bearings.
Equipped with an RS485 (Modbus) interface (RSA/RSB wires), the fan integrates seamlessly with PLCs and building management systems (BMS). The FG signal (5 pulses/rev) provides precise RPM feedback for real-time monitoring, while 0–10VDC/PWM control allows for easy speed adjustment—critical for maintaining consistent temperatures in food cold storage.
The fan includes comprehensive safeguards: motor current limitation, soft-start protection, under/over-voltage detection, thermal overload protection, locked-rotor detection, and reverse polarity protection. These features prevent component damage, reduce downtime, and ensure compliance with food safety and industrial safety standards.
Designed to maintain stable temperatures and airflow in refrigerated warehouses, cold rooms, and food processing facilities, the fan’s high static pressure overcomes duct resistance, while its corrosion-resistant impeller withstands low temperatures (-25℃ min) and high humidity (5%–90% RH).
Ideal for welding exhaust systems, fume extraction, and general factory ventilation, the fan’s powerful airflow removes pollutants and hot air, improving indoor air quality and worker safety. Its durable construction resists industrial contaminants and frequent use.
In air handling units (AHUs) and ducted air supply systems for malls, hotels, and office buildings, the fan acts as a booster to enhance airflow in long duct runs, ensuring consistent comfort across large spaces.
Suitable for industrial ovens, drying systems, and machinery enclosures, the fan’s high static pressure and airflow efficiently dissipate heat from equipment, preventing overheating and extending operational life.
The glass-fiber-reinforced plastic (GFRP) impeller offers superior corrosion resistance compared to metal, making it ideal for humid cold storage or environments with chemical fumes. It maintains structural integrity at extreme temperatures (-25℃ to 60℃) and resists rust or degradation, ensuring a longer lifespan than metal impellers in harsh conditions.
Yes. Use the RSA/RSB wires to connect the fan to a Modbus-enabled control system (PLC/BMS). This allows you to adjust speed, monitor RPM, and receive fault alarms remotely—essential for managing large cold storage facilities or industrial ventilation networks efficiently.
The fan is designed for industrial and commercial settings. For noise-sensitive areas (e.g., retail attached to cold storage), install acoustic ducting or reduce speed via PWM/Modbus control. At lower RPM, noise levels decrease while maintaining sufficient airflow for most applications.
