The FB3G190-48PY-71 is a high-efficiency 190mm backward centrifugal fan engineered for demanding industrial cooling applications. Powered by a 48V DC brushless motor (BLDC72), it delivers robust airflow and static pressure within a wide voltage range (36–57V DC). Featuring a corrosion-resistant glass-fiber-reinforced plastic impeller and IP44-rated die-cast aluminum housing, it complies with CE, RoHS, ISO9001, and ErP 2015 standards for reliable operation in harsh environments.
Optimized Pressure-to-Power Ratio:
Generates 480 Pa max static pressure at 665 m³/h airflow with only 72W power consumption, ideal for energy-conscious industrial ventilation.
Chemical-Resistant Design:
Glass-fiber-reinforced plastic impeller withstands corrosive fumes and humid conditions, extending service life in aggressive environments.
Real-Time System Diagnostics:
Provides FG tachometer output (2 pulses/revolution) for precise RPM monitoring and supports PWM/0–10VDC speed control for dynamic thermal management.
Robust Electrical Protections:
Integrated safeguards include reverse polarity, motor lock detection, and over/under-voltage cutoffs—ensuring stability in volatile power conditions.
Chemical Processing: Fume extraction in laboratories, solvent handling stations, and mixing tanks.
Food Production: Cooling for industrial ovens, packaging machinery, and refrigeration units.
Electronics Manufacturing: Thermal management in SMT reflow ovens, test chambers, and power supply racks.
Water Treatment: Ventilation for control panels in pump stations and filtration facilities.
Q: Is the impeller suitable for high-humidity environments?
A: Yes—the glass-fiber reinforcement provides excellent moisture and chemical resistance.
Q: What direction does the impeller rotate?
A: Clockwise when viewed toward the rotor (standard for backward centrifugal designs).
Q: Can I customize the cable length?
A: Yes—standard leads can be modified for specific installation requirements.
Q: How accurate is the FG tachometer signal?
A: It outputs 2 pulses per revolution, enabling precise speed feedback for system diagnostics.
