The FK3G225-85PY-90 is a high-performance DC centrifugal fan designed for applications requiring a balance of strong airflow, static pressure, and quiet operation. Operating on an 85VDC system (with a wide 68-102VDC range), it delivers 1,202 m³/h (1,707 CFM) of air against a static pressure of 514 Pa (2.06 in.wg). Its efficient brushless DC motor (BLDC92) and optimized backward-curved impeller make it an ideal choice for demanding cooling and ventilation tasks where electrical noise, energy consumption, and acoustic performance are concerns.
High-Efficiency DC Operation & Wide Voltage Range
Engineered for 85VDC systems but stable across a broad 68-102VDC range, this fan is highly adaptable to voltage fluctuations common in industrial and renewable energy settings (e.g., battery banks, solar systems). It achieves a high airflow-to-power ratio, consuming only 144W at full load.
Optimized for High Static Pressure & System Resistance
The backward-curved centrifugal design and 7-blade glass-fiber reinforced plastic impeller are engineered to move air efficiently against significant resistance (514 Pa), making it perfect for pushing air through dense heat sinks, long ducts, or filtration systems.
Low Acoustic Footprint
Despite its high performance, the fan operates at a remarkably low noise level of 68.3 dB(A), a key advantage for use in noise-sensitive environments like medical facilities, laboratories, or office equipment.
Robust Build with Integrated Protections
Housed in an IP44-rated casing for protection against dust and water splashes, it includes critical electronic safeguards: soft-start, over/under-voltage lockout, thermal overload protection, and locked-rotor detection, ensuring reliability and longevity (50,000 hours L10 life).
Telecom & Network Infrastructure: Cooling high-density servers, routers, and 5G base station cabinets.
Medical & Diagnostic Equipment: Providing reliable, quiet cooling for imaging machines (CT, MRI) and analyzers.
Industrial Power Electronics: Ventilation for variable frequency drives (VFDs), PLC enclosures, and power converters.
Specialized HVAC: Energy recovery ventilators (ERVs) or small air handling units (AHUs) requiring DC power.
Q: Can this fan be used with a standard 48V or 24V power supply?
A: No, it is specifically designed for an 85VDC nominal voltage. Using a significantly lower voltage will prevent it from starting or operating correctly. A DC-DC converter is required to step up the voltage from a lower source.
Q: How does the plastic impeller handle high RPMs and is it durable?
A: The impeller is made from propylene reinforced with glass fiber, a material chosen for its high strength-to-weight ratio and resistance to fatigue. It is specifically engineered and balanced (to G6.3 standard) for reliable, vibration-free operation at its rated 2700 RPM.
Q: What is the purpose of the FG (tachometer) signal?
A: The FG wire (white) provides a speed feedback signal, outputting 4 pulses per revolution. This can be used by a controller to monitor real-time fan speed for system health monitoring or to implement speed-based alarm functions.
