The FK3G190-85PS-90 DC Centrifugal Fan by Fanova (Suzhou) is a compact yet powerful airflow solution engineered for high-static-pressure applications. Featuring a backward-curved impeller and bracket-mount design, it delivers exceptional pressure (782 Pa) with low noise (73 dB(A)). Its 85VDC brushless motor ensures energy-efficient operation in confined spaces like electronics enclosures and industrial machinery.
High-Pressure DC Performance
Powered by a robust 85VDC motor (Model: BLDC92), this fan achieves 782 Pa static pressure—ideal for overcoming airflow resistance in dense systems. Wide voltage tolerance (68–102 VDC) ensures stability under fluctuating power conditions.
Optimized Centrifugal Design
The 190mm fiberglass-reinforced impeller with 7 backward-curved blades maximizes air displacement efficiency. Generates 903 m³/h airflow while maintaining quiet operation (73 dB(A)), critical for noise-sensitive environments.
Plug-and-Play Control
Simplified wiring supports 0–10VDC/PWM speed modulation and tachometer (FG) output (4 pulses/revolution). Pre-installed bracket enables tool-free mounting in any orientation.
Industrial Resilience
Rated IP44 for dust/moisture resistance and operates continuously (-25°C to 60°C). Ball bearings ensure 50,000-hour lifespan (L10) under 40°C/65% RH conditions.
Compact Electronics Cooling: Server blades, UPS systems, and power supplies requiring high-pressure ventilation.
Medical Equipment: MRI machines, diagnostic devices, and laser cooling.
Industrial Automation: CNC control cabinets, robotics, and PLC enclosures.
Transportation Systems: EV battery thermal management and train electronics cooling.
Q1: Is this fan suitable for 24/7 operation?
A: Yes. Its S1 continuous duty rating and thermal protections allow uninterrupted use.
Q2: Can PWM control replace the 0–10VDC input?
A: Absolutely. Both control methods are natively supported via the yellow wire (see Section 5).
Q3: Why choose centrifugal over axial fans here?
A: Centrifugal designs excel in high-static-pressure scenarios (e.g., pushing air through filters or dense components), whereas axial fans prioritize high-volume/low-pressure flow.
Q4: Does the FG signal require external pull-up voltage?
A: No—unlike EC fans, this DC model’s FG output is self-powered. Connect directly to monitoring systems.
