The FK3G450-48AL-20 is a large-scale centrifugal fan engineered for high-volume ventilation in industrial and commercial spaces. Combining a massive 450mm aluminum impeller with a pre-installed mounting bracket, it delivers exceptional airflow (4,080 m³/h) at low noise levels (63 dB(A)) while operating on 48VDC power. Designed for easy deployment and durability, it excels in applications requiring efficient air exchange without structural complexity.
Industrial-Grade Airflow Capacity
Moves 4,080 m³/h air—equivalent to large-scale HVAC systems—while consuming only 265W. The 6-blade aluminum impeller ensures optimal energy transfer at low RPM (1,050 min⁻¹).
Integrated Bracket for Rapid Installation
Pre-attached mounting bracket enables single-person installation in ducts, ceilings, or equipment frames—reducing setup time by 50% compared to modular assemblies.
Quiet High-Efficiency Operation
Operates at 63 dB(A)—unusually quiet for its size—thanks to precision-balanced aluminum impeller and low-speed EC motor. Ideal for noise-sensitive environments like theaters or laboratories.
Large-Space Ventilation: Auditoriums, aircraft hangars, convention centers.
Industrial Air Management: Foundry exhaust, paper mill drying systems, bulk material handling.
Renewable Energy Integration: Solar/wind farm battery cooling, off-grid ventilation.
Agricultural Mega-Structures: Grain silos, livestock mega-barns.
Q: Why aluminum over plastic for the impeller?
A: Aluminum provides superior strength for large diameters (450mm), preventing flex at high torque while resisting corrosion in humid environments.
Q: Can it run on solar power without inverters?
A: Yes—compatible with 48V DC solar systems (36–57VDC range). Avoids AC conversion losses.
Q: How to handle the 15kg+ weight during installation?
A: Use the integrated lifting lugs (see product drawing); always mount with ≥4 M8 bolts.
Q: Is the 63 dB(A) noise sustainable at full load?
A: Verified at max airflow (4080 m³/h). Noise reduces linearly with speed via PWM control.
