The FB3G190-24PY-70 is an ultra-efficient DC centrifugal fan engineered for precision cooling in compact, low-power systems. Powered by a 24VDC brushless motor (BLDC72), it delivers focused airflow up to 621 m³/h (365 CFM) and static pressure up to 403 Pa (1.61 in.wg). Designed for silent operation and exceptional energy efficiency, it excels in applications where space, weight, and power constraints are critical.
Ultra-Low Power & Voltage Flexibility
Operates at just 57W (±10%) across a wide 16–28VDC range, making it ideal for battery-powered devices, portable equipment, and solar-powered systems where energy conservation is paramount.
High-Speed Quiet Operation
Achieves 2950 RPM (±5%) while maintaining a remarkably low 68 dB(A) noise profile—enabling powerful airflow in noise-sensitive environments like medical devices or residential settings.
Lightweight & Chemically Resistant
Features a unique 7-blade plastic/glass-fiber impeller (190mm) that reduces weight and resists corrosion, paired with an IP44-rated aluminum housing for durability in humid/dusty conditions.
Portable Electronics: Cooling drones, projectors, or portable diagnostic tools.
Lab/Medical Devices: Ventilation for microscopes, analyzers, or handheld medical instruments.
Low-Voltage Systems: Solar-powered enclosures, RV ventilation, or battery-backed cabinets.
Compact Appliances: 3D printers, small-scale HVAC units, or IoT environmental controls.
Q: Can it run on unstable DC sources (e.g., batteries)?
A: Yes—its wide voltage range (16–28VDC) tolerates fluctuations during battery discharge/recharge cycles.
Q: Why choose plastic/glass-fiber blades over metal?
A: Lighter weight (reduces inertia), corrosion resistance, and lower noise at high RPM—critical for portable devices.
Q: How does its 403 Pa pressure handle ducted systems?
A: Optimized for short ducts or filters in compact setups (e.g., air purifiers), not heavy industrial ductwork.
Q: Is speed control simple for low-voltage projects?
A: Yes—basic 3-wire control (+24VDC, PWM, GND) integrates easily with Arduino/Raspberry Pi controllers.
