The FB3G355-48AY-20 is an industrial-grade DC backward centrifugal fan engineered for high-efficiency air movement in demanding environments. Driven by a robust BLDC102 external rotor motor, it combines high static pressure (580 Pa) with substantial airflow (3,350 m³/h). Its die-cast aluminum impeller and IP44-rated housing ensure durability in harsh conditions, while compliance with CE, RoHS, and ErP standards guarantees safety and environmental responsibility.
High-Performance Air Handling
Delivers robust 580 Pa static pressure and 3,350 m³/h airflow, optimized for systems requiring strong ventilation against resistance (e.g., HVAC, industrial enclosures).
Intelligent Control & Feedback
Supports 0–10V DC or PWM speed modulation for dynamic airflow adjustment, paired with an FG tachometer signal (3 pulses/revolution) for real-time RPM monitoring and system integration.
Industrial-Grade Resilience
Features an all-aluminum construction, ball bearings, and wide voltage tolerance (36–57V DC). Multiple protections (soft-start, over/under-voltage, thermal shutdown, reverse polarity) ensure reliability in -25°C to 60°C environments.
Plug-and-Play Flexibility
Operates in any mounting orientation with standardized wiring. Optional cable customization and communication protocol swaps (beyond default PWM/0–10V) offer application-specific adaptability.
Industrial HVAC systems requiring high static pressure.
Server racks/electrical enclosures for critical heat dissipation.
Manufacturing equipment (e.g., laser cutters, ovens) demanding reliable cooling.
Renewable energy installations (battery cooling, inverter thermal management).
Q: Can the fan be wired for reverse rotation?
A: No. The impeller rotates clockwise (viewed toward the rotor); reversing polarity triggers protection circuitry.
Q: What does the FG (tachometer) signal output?
A: It generates 3 pulses per revolution, enabling real-time speed monitoring or system feedback loops.
Q: Is the power cable user-replaceable?
A: No. Damaged cables require factory repair/replacement (Section 7) to ensure safety and compliance.
