The FK3G250-48PL-20 is a high-pressure DC centrifugal fan engineered for applications demanding extreme static pressure performance. Operating at 48VDC, it delivers exceptional force (1248 Pa) while maintaining substantial airflow (1941 m³/h), making it ideal for compact systems requiring powerful ventilation against high resistance. Equipped with a universal bracket and IP44-rated construction, it combines rugged reliability with flexible mounting for industrial environments.
Ultra-High Pressure Output
Generates industry-leading 1248 Pa static pressure—designed to overcome severe resistance in dense filtration systems, pneumatic conveyors, or pressurized enclosures.
Optimized Power Density
420W DC motor with 3720 RPM delivers maximum force in a compact 250mm footprint. Wide voltage input (36–57VDC) ensures stability during power fluctuations.
Industrial Protections
Integrated soft-start, reverse polarity, and thermal overload safeguards. Ball bearings rated for 50,000 hours (L10) at 40°C ensure longevity in continuous operation.
Precision Control & Feedback
Supports 0–10V/PWM speed modulation with FG tachometer output (3 pulses/rev) for real-time RPM monitoring and system synchronization.
Industrial Filtration: High-pressure HEPA/ULPA filters in cleanrooms or medical facilities.
Material Conveying: Pneumatic transport systems for powders or granular materials.
Laboratory Equipment: Fume hoods, biosafety cabinets, and analytical instrument cooling.
Pressurized Enclosures: Electronics cooling in sealed industrial control panels.
Q: Why is power consumption higher than similar-sized fans?
A: High pressure (1248 Pa) requires significant energy. Efficiency is optimized for resistance-heavy applications.
Q: Can it run continuously at maximum pressure?
A: Yes, but monitor temperature. Thermal protection activates at >85°C (electronics) or >80°C (bearings).
Q: Is the plastic impeller durable enough?
A: Glass-fiber-reinforced polypropylene resists deformation at high RPM/stress. Avoid abrasive particulates.
Q: How does FG pulse count (3/rev) affect monitoring?
A: Lower resolution than 5-pulse models but sufficient for speed alarms. Use averaging for precise RPM calculation.
Q: Can two fans operate in parallel?
A: Yes—doubles airflow at similar pressure. Ensure independent power circuits to avoid overload.
