The FK3G190-48PY-70 is a compact DC backward centrifugal fan engineered for high-static-pressure applications. Operating at 48VDC, it delivers focused airflow (621 m³/h) with exceptional static pressure (403 Pa), ideal for confined spaces requiring forceful ventilation. Featuring a 190mm glass-fiber-reinforced impeller and IP44-rated construction, it combines durability with flexible bracket-mounting for versatile industrial integration.
High-Pressure Performance
Generates 403 Pa static pressure—optimized for overcoming resistance in ducted systems or filtration units. The backward-curved centrifugal design maximizes efficiency while reducing turbulence noise (68 dB(A)).
Extended Operational Resilience
Wide voltage input (36–57V DC) with built-in protections (reverse polarity, over/under-voltage, thermal overload). Rated for 50,000 hours (L10) at 40°C with ball bearings and industrial-grade materials.
Smart Control Integration
Supports 0–10V/PWM speed modulation and provides FG tachometer output (2 pulses/revolution) for real-time RPM feedback, enabling seamless automation compatibility.
Space-Optimized Mounting
Includes a universal bracket for multi-directional installation (vertical/horizontal). IP44 protection ensures reliability in dusty or humid environments (e.g., enclosures, machinery).
Electronics Cooling: High-pressure cooling for server racks, power supplies, and inverters.
Filtration Systems: Airflow boost in HEPA filters, dust collectors, or fume extractors.
Medical Equipment: Ventilation for diagnostic devices or sterilization units.
Transportation: Thermal management in EV charging stations or rail electronics.
Q: Why choose centrifugal over axial fans?
A: Centrifugal fans excel in high-pressure, low-airflow scenarios (e.g., ducted systems), while axial fans suit high-volume, low-resistance applications.
Q: Can RPM be monitored without FG wiring?
A: No—FG output (2 pulses/rev) is required for tachometer feedback. Omit wiring if unused.
Q: Is the bracket corrosion-resistant?
A: The aluminum housing offers inherent corrosion resistance. Avoid acidic/alkaline environments.
Q: Why does airflow decrease at higher static pressure?
A: This is intrinsic to centrifugal designs. Refer to the performance curve for optimal operating points.
Q: Can two fans operate in series for higher pressure?
A: Not recommended—may cause instability. Consult support for custom high-pressure solutions.
