FK3G190-48PY-71
Fanova
The FK3G190-48PY-71 is a premium high-pressure 48V DC centrifugal fan integrated with a sturdy support bracket, specifically engineered to meet the demanding ventilation needs of confined spaces and industrial environments. Powered by an advanced BLDC motor (72W rated power, 36~57VDC voltage range), this compact 190mm fan delivers exceptional performance with a maximum airflow of 665 m³/h and a robust 480 Pa static pressure—making it the ideal choice for overcoming air resistance in ducted systems, filtered enclosures, and dust emission applications in workshops.
With an IP44 protection level, aluminum alloy motor, and glass-fiber-reinforced impeller, this backward centrifugal fan combines durability and fashion design, ensuring reliable operation in high-vibration industrial settings, medical equipment, and HVAC subsystems. Its 50,000-hour working life (L10 at 40℃) and S1 continuous duty rating make it suitable for 24/7 operation, while precision control options and comprehensive safety features elevate its usability across diverse professional scenarios.

This high-speed centrifugal fan generates an impressive 480 Pa static pressure, a critical advantage for pushing air through dense filters, narrow ducts, or dust-laden industrial paths while maintaining a consistent 665 m³/h airflow. Its wide voltage tolerance (36~57VDC) ensures stable performance even in variable power conditions, making it reliable for workshops and industrial machinery.
Equipped with a reinforced support bracket, the fan enables secure mounting in high-vibration environments—perfect for industrial equipment like laser cutters and CNC control cabinets. The glass-fiber-reinforced impeller and high-quality ball bearings support continuous 3300 RPM operation (S1 duty), while the aluminum alloy motor enhances heat dissipation, contributing to a 50,000-hour service life.
Supporting 0~10VDC/PWM speed modulation, the fan allows precise airflow adjustment to match specific application needs. The FG tachometer output (2 pulses/revolution) enables real-time speed monitoring. Integrated safeguards include soft-start, reverse polarity protection, thermal overload protection, motor current limitation, and locked-rotor protection, preventing damage during operational anomalies.
Ideal for cooling laser cutters, 3D printers, CNC control cabinets, and other industrial equipment, where high static pressure is required to overcome enclosure resistance. It also excels in dust emission systems for workshops, efficiently removing particulate matter.
Suitable for ventilation in sensitive medical devices such as MRI/CT imaging machines and sterilization units, where reliable airflow and low maintenance are critical. The IP44 protection level and clean design meet medical industry hygiene and durability standards.
Perfect for air handling in cleanrooms, fume hoods, and paint booths, where consistent airflow through filtration systems is essential. The fan’s ability to maintain pressure through dense filters ensures a contaminant-free environment.
Serves as an auxiliary pressure boost in ducted residential and commercial HVAC systems, improving airflow in restricted ductwork and enhancing overall system efficiency.
Centrifugal fans excel in high-pressure scenarios (e.g., filtered/ducted paths or dust emission systems), where axial fans struggle to overcome resistance. This 48V DC model delivers targeted airflow in confined spaces, making it more suitable for industrial and medical applications requiring consistent pressure.
The bracket provides fixed mounting points for secure installation. For custom orientations, mechanical adaptation is required to ensure stability, especially in high-vibration industrial settings.
At full load, the fan operates at 70 dB(A), which is well-suited for industrial workshops and manufacturing facilities. However, in quiet environments like laboratories or offices, additional dampening measures may be needed to reduce noise.
Yes, it is rated for S1 continuous duty with a 50,000-hour lifespan (L10 at 40℃), making it reliable for round-the-clock operation in critical applications such as medical equipment and industrial production lines.
