The FB3G250-24PL-91 is a high-pressure DC centrifugal fan engineered for demanding industrial cooling applications. Combining a 250mm fiberglass-reinforced impeller with a 24VDC BLDC motor (Model BLDC92), it delivers robust airflow (1,475 m³/h) and exceptional static pressure (885 Pa) while maintaining moderate noise levels (71 dB(A)). Designed for IP44 protection and wide voltage input (16–28VDC), it excels in systems requiring powerful ventilation against high resistance.
High-Pressure Performance
Generates 885 Pa static pressure—ideal for overcoming dense obstructions in ducted systems or compact enclosures, while moving 1,475 m³/h of air.
Optimized Energy Efficiency
Operates at 2,950 RPM (±5%) with 192W power consumption, balancing high output with controlled energy use via 0–10VDC/PWM speed modulation.
Industrial Durability
Features a fiberglass-reinforced plastic impeller, ball bearings, and IP44 protection for reliable 50,000-hour operation (L10) in temperatures from -25°C to 60°C.
Plug-and-Play Control
Standardized wiring (24VDC input, PWM control, 4-pulse FG tachometer) simplifies integration, with soft-start and reverse-polarity protection.
Industrial Cooling: High-resistance thermal management in CNC machines, laser cutters, or power converters.
HVAC Systems: Pressure-boosting in ducted ventilation or air-handling units.
Medical Equipment: Cooling for MRI/CT scanners requiring stable, high-pressure airflow.
Server Racks: Overcoming restricted airflow in densely packed data centers.
Q: Why is static pressure (885 Pa) critical?
A: Essential for pushing air through filters, long ducts, or dense electronics—ensures consistent cooling where standard fans fail.
Q: Can it withstand dusty environments?
A: IP44 rating resists dust ingress but avoid direct particulate blasts; periodic cleaning recommended.
Q: How does the 7-blade design help?
A: Blades are aerodynamically tuned to reduce turbulence at 2,950 RPM, minimizing noise while maximizing pressure.
Q: Safe for continuous 24/7 operation?
A: Yes—rated for 50,000 hours (L10) at 40°C with ball bearings preventing wear.
