Product Overview

The FG3G450-48PL-20 Axial Flow Industrial Fan from Fanova is a high-capacity, low-noise cooling and ventilation solution engineered for demanding industrial environments. With a 450mm diameter, 48V DC brushless (BLDC) motor, and propylene with glass-fiber reinforced impeller, this fan delivers an impressive maximum airflow of 5450 m³/H while operating at just 63 dB(A)—making it a quiet high-volume axial fan ideal for extended use. It features an IP44 protection rating, Class B insulation, and a durable guard grille, ensuring resistance to dust, moisture, and accidental contact. Designed to tolerate voltage fluctuations (3657VDC), it integrates PWM/010V speed control and FG tachometer output, making it compatible with off-grid power systems, battery backups, and industrial automation setups.

Key Features

High-Volume Airflow Delivery

This axial flow fan moves up to 5450 m³/H of air, making it perfect for cooling heavy machinery, ventilating large warehouses, and clearing fumes or dust from expansive spaces. The 7-blade impeller design optimizes airflow efficiency while resisting corrosion and wear.

Ultra-Quiet Operation

With a sound pressure level of just 63 dB(A), the fan operates significantly quieter than standard industrial axial fans—ideal for environments where noise pollution is a concern, such as workshops, labs, and commercial facilities.

Stable 48V DC Performance

Optimized for industrial power systems, the fan tolerates voltage drops to 36VDC without performance loss. It is compatible with battery backups, solar hybrid systems, and off-grid setups, making it a versatile choice for renewable energy applications.

Safety & Durability

The fan includes a removable guard grille to prevent accidental contact with blades while maintaining unimpeded airflow. The IP44 rating protects against dust and water splashes, and the propylene with glass-fiber reinforced impeller resists oil mist, coolants, and abrasive particles.

Intelligent Control & Monitoring

Pre-wired for 0~10VDC / PWM speed control, the fan allows seamless adjustment via external controllers. The FG tachometer output (4 pulses/revolution) enables real-time RPM tracking, supporting maintenance alerts and operational oversight.


Applications

Industrial Machinery Cooling

Cools CNC machines, laser cutters, and hydraulic systems in workshops. The corrosion-resistant impeller withstands oil mist and metal shavings, ensuring long-term reliability in harsh industrial conditions.

Large-Space Ventilation

Ventilates warehouses, factories, and agricultural barns, clearing heat, dust, and fumes. The high-volume airflow ensures consistent air circulation across expansive areas.

Renewable Energy Thermal Management

Extracts heat from solar inverters and battery storage cabinets. Its 48V DC compatibility aligns with off-grid power systems, making it a sustainable choice for renewable energy setups.

Commercial Ventilation Support

Boosts airflow in restaurant ductwork, lab exhaust systems, and retail spaces. The IP44 rating handles steam and occasional splashes, while the quiet operation suits customer-facing environments.

Agricultural Ventilation

Ideal for ventilating barns and greenhouses, regulating temperature and humidity to protect livestock and crops. The durable design resists agricultural dust and moisture.


FAQ

How do I clean grease or dust from the impeller?

Wipe the blades with a non-abrasive degreaser or damp cloth. Avoid high-pressure water, as this may damage the fan’s electronics.

Can I remove the guard grille?

Yes, the guard grille is removable for cleaning or maintenance. However, reinstallation requires torque calibration (refer to the user manual), and the fan should never operate without the grille.

Is it possible to daisy-chain multiple fans to one controller?

Absolutely. You can link the PWM control wires of multiple fans to a single controller to synchronize speed across units, simplifying centralized control.

What is the fan’s operating temperature range?

The fan operates reliably between -25℃ (minimum) and 60℃ (maximum). The IC heat sink can withstand up to 115℃, and the lead wire is rated for 120℃.

Does the fan work with solar power systems?

Yes, the fan’s 48V DC voltage and 36~57VDC range make it compatible with solar hybrid systems and battery backups, making it an excellent choice for off-grid applications.
