I. Product Description
The FANOVA FB3G400-2APK-20 EC rearward centrifugal fan is an industrial-grade high-efficiency ventilation device developed and manufactured by Fanova (Suzhou) Motor Technology Co., LTD. It is specifically designed for harsh industrial environments, with core compatibility for climate control in food refrigeration systems. It can also be widely used in factory ventilation, HVAC pressurization, and industrial equipment cooling.
This fan is equipped with a BLEC102 external rotor EC motor, operating at a rated voltage of 230VAC, with a wide voltage adaptability range of 184-270VAC, capable of stably handling industrial power grid fluctuations. In terms of performance, its rated speed reaches 1500±5% RPM, delivering a maximum airflow of 5755 m³/H (3386.82 CFM) and a maximum static pressure of 785 Pa (3.14 In.wg), while power consumption is controlled at 500±10% W, balancing high-efficiency ventilation with energy saving.
In terms of structural design, the fan adopts a glass fiber reinforced polypropylene impeller, paired with die-cast aluminum alloy end caps and an electrophoretic black-coated rotor, which is not only lightweight but also possesses excellent corrosion resistance and rust prevention performance. It has an IP54 protection rating and Class B insulation class, enabling stable operation in environments with operating temperatures ranging from -25℃ to 60℃ and operating humidity from 5% to 90% RH. Its L10 lifespan is as long as 50,000 hours (at 40℃ room temperature and 15%-65% RH humidity), fully meeting the needs of long-term continuous operation of industrial equipment.
II. Product Advantages
1. High Efficiency and Energy Saving, Reducing Operating Costs
Compared to similar centrifugal fans, this product maintains a high static pressure output of 785Pa while consuming only 500W of power, reducing energy consumption by more than 30%. 1. Wide voltage design (184-270VAC) adapts to power grid fluctuations in different regions, avoiding energy waste caused by voltage instability. Long-term use can significantly save businesses on electricity costs, meeting EU ErP 2015 energy efficiency standards, combining economic and environmental value.
2. Durable and damage-resistant, suitable for harsh environments. The impeller is made of glass fiber reinforced polypropylene, which is more than 30% lighter than traditional metal impellers, with lower inertia and faster response speed. It can withstand the effects of harsh environments such as humidity and chemical corrosion, making it particularly suitable for the high humidity environment of food cold storage and factory fumes and exhaust gas scenarios. The ball bearing combined with the electrophoretic anti-rust rotor, along with the IP54 protection rating, effectively prevents dust and moisture intrusion, extending equipment life and reducing maintenance frequency and costs.
3. Intelligent and Controllable, Compatible with Industrial Automation Systems
Supports two basic control methods: 0-10VDC voltage control and 1-10KHz PWM pulse control. It is also equipped with RS485/MODBUS interfaces (RSA/RSB wiring), allowing seamless integration with PLCs, building management systems (BMS), and other industrial automation platforms. Through FG signal output (3 pulses per revolution), it can provide real-time feedback of speed data, enabling remote speed adjustment, status monitoring, and fault alarms. No manual on-site operation is required, adapting to the "unmanned" management needs of modern industry and improving overall production efficiency.
4. Multiple Protections Ensure Safe and Stable Operation
Built-in multiple safety mechanisms including motor current limiting, soft start protection, over/under voltage detection, electronic/motor thermal overload protection, stall protection, and reverse polarity protection, effectively addressing emergencies such as power grid anomalies, operational errors, and equipment failures, preventing fan burnout or damage. Leakage current is controlled to ≤3.5mA (270VAC test for 3 seconds), and insulation withstand voltage reaches 1800VAC 50Hz for 1 second, complying with multiple international safety and quality standards such as CE, RoHS, and ISO9001, ensuring ample safety and reliability.
III. Product Features
1. Core Performance Features
Strong Ventilation Capacity: A large air volume of 5755m³/H enables rapid air circulation in large spaces; a high static pressure of 785Pa overcomes ventilation challenges in long ducts and high-resistance scenarios, making it suitable for large industrial spaces and complex duct systems.
Low-noise design: Sound pressure level is controlled at 80±5% dB(A), meeting industrial noise standards. For use in semi-public areas, noise can be further reduced by adding acoustic ducting or PWM speed control.
Continuous and stable operation: Adopting S1 continuous duty, it can operate 24 hours a day without interruption, meeting the needs of industrial production, refrigeration, and other scenarios requiring continuous ventilation. Speed fluctuations are controlled within ±5%, ensuring stable airflow and static pressure output.

Customizable adaptation: Power cord length can be customized according to user needs. The communication protocol (default 0-10V/PWM) can also be changed by contacting the manufacturer's technical personnel to meet the personalized connection and control needs of different scenarios.
Clear Wiring System: High-voltage (brown L, black N, yellow-green PE) and low-voltage (control and communication lines) are clearly categorized with distinct wire color markings. Detailed wiring diagrams and simplified schematics facilitate quick installation and commissioning by professionals, reducing the risk of wiring errors.
3. Compliance and Environmental Features: Complies with multiple domestic and international standards, including EN ISO12100 safety standards for machinery, EN 60204-1 safety standards for electrical equipment, and GB12350 safety requirements for small-power motors. It is CE and RoHS certified, releases no harmful substances, and balances safety and environmental protection. The fan rotor balance meets JB/T 9101 G6.3 standards, resulting in low vibration during operation, reducing interference with surrounding equipment and improving the overall stability of the production environment.

During transportation, the fan must be secured in specialized packaging to avoid violent collisions and compression, preventing deformation of the impeller and casing or loosening of internal wiring;
The packaging must have sufficient moisture and dust protection to prevent rainwater and dust from entering the equipment during transportation;
The ambient temperature during transportation must be controlled between -40℃ and 75℃ to prevent damage to electronic components and bearings from extreme high or low temperatures;
When handling, do not pull the fan lead wire directly; use the equipment casing or a specialized handling structure to prevent the lead wire solder joints from detaching.
2. Storage Requirements
The storage environment must be dry and well-ventilated, with humidity controlled between 5% and 95% RH and a temperature range of -40℃ to 75℃. Avoid direct sunlight, rain, and proximity to heat sources or corrosive substances.
The fan must be placed on a flat surface, avoiding tilting or stacking to prevent structural deformation.
Before long-term storage (more than 3 months), check the fan's appearance for damage and ensure the wiring terminals are clean. During storage, a monthly visual inspection is recommended to ensure the equipment is free of rust and damage.
The storage packaging must be intact. If temporary removal for inspection is necessary, the packaging must be resealed afterward to prevent dust ingress.
