The FB3G355-2APK-20 is a high-performance EC centrifugal fan engineered for extreme-duty industrial applications demanding massive airflow and static pressure. Featuring a 355mm fiberglass-reinforced impeller, IP54-rated housing, and advanced control interfaces, it delivers unparalleled ventilation power (4,720 m³/h) for harsh environments while complying with CE, RoHS, and ErP2015 standards.
Industrial-Grade Airflow & Pressure
Generates colossal 4,720 m³/h airflow with exceptional static pressure (825 Pa)—ideal for overcoming resistance in long-duct systems or dense industrial equipment cooling.
Smart Control Integration
Supports MODBUS-RTU via RS485 (RSA/RSB terminals) for networked automation, plus +10VDC output, FG tachometer (5 pulses/rev), and dry-contact alarms (NC/COM) for failure alerts.
Enhanced Environmental Resistance
IP54-rated construction exceeds standard IP44, providing superior protection against dust ingress and water jets in foundries, chemical plants, or outdoor installations.
Energy-Efficient Powerhouse
Optimized 7-blade design achieves high airflow at moderate RPM (1,850±5%), reducing energy consumption (500W) while minimizing acoustic impact (84 dB(A)).
Heavy Industrial Ventilation: Welding fume extraction, furnace cooling, mining ventilation shafts.
Power Generation: Turbine hall cooling, transformer thermal management, high-capacity UPS systems.
Process Industries: Plastic extrusion cooling, industrial dryer exhaust, paper mill machinery.
Large-Scale HVAC: Commercial air handlers, data center cooling units.
Q: Can MODBUS override local speed controls simultaneously?
A: Yes—MODBUS-RTU commands take priority over 0–10VDC/PWM inputs for centralized system control.
Q: What triggers the alarm contacts (NC/COM)?
A: Contacts open during motor overload, bearing failure, or locked rotor—connect to PLC/SCADA for real-time alerts.
Q: Is the fiberglass impeller suitable for corrosive environments?
A: Yes—glass-reinforced polypropylene resists mild chemicals. For acidic/alkaline exposure, request optional PP+GF30 variant.
Q: Minimum clearance for side intake?
A: Maintain ≥30% impeller diameter (107mm) unobstructed space around inlet (§5) to prevent airflow starvation.
