The FK3G250-48PL-91 is a high-performance bracket-mounted centrifugal fan engineered for demanding cooling applications where space efficiency and extreme static pressure are critical. Featuring a robust 250mm fiberglass-reinforced impeller and 48VDC brushless motor (Model BLDC92), it delivers powerful airflow (1,475 m³/h) and industry-leading static pressure (885 Pa). Designed for industrial enclosures, machinery, and HVAC subsystems requiring reliable thermal management in compact footprints.
Extreme Static Pressure Performance
Generates 885 Pa of force—ideal for overcoming dense filters, long duct runs, or confined spaces—while maintaining 1,475 m³/h airflow via its optimized 7-blade fiberglass impeller.
Industrial-Grade Resilience
IP44-rated housing resists dust/moisture ingress; operates reliably from -25°C to 60°C. Ball bearings ensure 50,000+ hours (L10) of continuous duty in harsh environments.
Smart Speed Control
0–10VDC/PWM input enables precise airflow tuning (20–100% speed). Integrated tachometer (FG signal) provides real-time RPM monitoring for system diagnostics.
Server Farms/Data Centers: High-pressure cooling for densely packed server racks.
Industrial Ovens & Dryers: Forced heat extraction from high-temp processing equipment.
EV Charging Stations: Thermal management for power electronics in compact enclosures.
Q: Why choose 48VDC over AC power?
A: 48VDC reduces electrical noise, improves efficiency, and simplifies integration with battery/solar systems—critical for off-grid or mobile applications.
Q: Can it handle vertical mounting?
A: Yes—the universal bracket supports 360° orientation adjustments for flexible installation.
Q: Is the fiberglass impeller durable?
A: Reinforced polypropylene resists warping at high temps and exposure to mild chemicals/oils.
Q: How to reduce noise (71dB at full speed)?
A: Use PWM control to run at 60–80% speed; noise drops significantly while retaining 70%+ static pressure.
