Brief Description
The FG3G400-2APN-20 is a large-diameter EC axial fan designed for ultra-high airflow and medium-to-low static pressure ventilation applications. Operating on 230VAC with a wide input range of 184–270VAC and compatibility with 50/60Hz mains, it delivers an exceptional airflow of up to 5900 m³/h at a static pressure of 240Pa. This fan features an advanced smart control interface that supports not only conventional 0–10VDC and PWM speed regulation but also includes an RS485 communication port for direct data exchange and centralized control via the MODBUS protocol with host systems or external controllers. Additionally, it incorporates an alarm switch for enhanced system monitoring reliability. It is well-suited for large-space ventilation, industrial exhaust, and cooling tower applications.
Product Specification
The FG3G400-2APN-20 is built around an external rotor EC motor and a 5-blade impeller made of glass-fiber reinforced plastic, with a diameter of 400mm, offering an optimal balance of light weight and structural strength. Its electrical features include a comprehensive set of control and communication terminals: a +10VDC reference voltage output, analog/PWM speed control input, FG tachometer output (5 pulses per revolution), RS485 communication lines (RSA/RSB), and independent alarm switch contacts (NC/COM). This allows users to achieve precise speed control, real-time status monitoring, and fault alarms through external control boards, enabling highly integrated automated management. The fan incorporates multiple safety mechanisms such as soft start, over/under voltage protection, locked-rotor protection, and reverse polarity protection, with a dielectric withstand voltage of 1800VAC. It boasts an IP54 protection rating, allowing continuous operation in temperatures from -25℃ to 60℃ and making it suitable for environments with dust and light water splashes. Mechanically, it features a die-cast aluminum housing and ball bearings, and supports installation in any orientation. Compliant with CE, RoHS, ErP, and international safety standards including EN ISO12100 and EN 60204-1, this fan is an ideal choice for high-airflow ventilation systems requiring intelligent networked control.

Safety Requirements
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 ou
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
