The FK3G355-48PK-20 is a large-format industrial centrifugal fan engineered for high-volume ventilation in demanding applications. Featuring a massive 355mm impeller powered by a robust 48V DC brushless motor (BLDC102), it delivers exceptional airflow while operating within a wide voltage range (36–57V DC). Its corrosion-resistant glass-fiber-reinforced plastic impeller and IP44-rated die-cast aluminum housing ensure durability in harsh environments, compliant with CE, RoHS, ISO9001, and ErP 2015 standards.
Industrial-Scale Airflow:
Moves 3,600 m³/h max airflow—ideal for large-space ventilation, factory cooling, or high-volume exhaust systems.
Low-Speed High-Torque Operation:
Optimized 1,450 RPM design reduces noise (77 dB(A)) while maintaining static pressure (580 Pa) for energy-efficient performance.
Heavy-Duty Construction:
102mm rotor diameter and 7-blade fiberglass-reinforced impeller withstand industrial particulates and mechanical stress.
Real-Time System Monitoring:
FG tachometer output (3 pulses/revolution) enables precise RPM tracking for predictive maintenance.
Factory Ventilation: High-bay cooling, welding fume extraction, or foundry exhaust systems.
Agricultural Infrastructure: Grain drying facilities, livestock barn ventilation, or greenhouse air circulation.
Industrial Process Cooling: Large machinery cooling, plastic injection molding, or industrial oven exhaust.
Energy Facilities: Transformer room ventilation, turbine hall cooling, or battery storage thermal management.
Q: Why choose low-RPM operation for industrial fans?
A: Lower RPM reduces wear, noise, and energy consumption while maintaining torque for high-resistance systems.
Q: Can this fan handle dusty environments?
A: Yes—the fiberglass-reinforced impeller resists abrasion from airborne particulates.
Q: Is it suitable for outdoor installation?
A: With IP44 rating, it withstands rain splashes and dust ingress—ideal for covered outdoor applications.
Q: How does the FG signal aid maintenance?
A: 3-pulse/revolution resolution alerts to speed drops indicating bearing wear or airflow blockages.
