FK3G190-85PS-90
Fanova
Fanova’s 85V DC backward centrifugal fan FK3G190-85PS-90 is a compact yet powerful airflow solution engineered for high-static-pressure applications. Designed with a bracket-mount configuration and a backward-curved impeller, this waterproof centrifugal fan delivers an impressive 782 Pa static pressure and 903 m³/h (531.42 CFM) airflow, making it ideal for overcoming resistance in dense systems such as filtered enclosures and precision equipment. Powered by a robust BLDC92 brushless motor, it operates within a wide voltage range of 68~102VDC, ensuring stability under fluctuating power conditions. With an IP44 protection level, 50,000-hour (L10) lifespan, and S1 continuous duty rating, this industrial centrifugal bracket fan is built to withstand the rigors of 24/7 operation in industrial, medical, and transportation environments.

Driven by a BLDC92 brushless motor, this 85V DC centrifugal fan excels in high-resistance environments, delivering 782 Pa static pressure to push air through filters, dense components, and restricted pathways. The wide voltage tolerance (68–102VDC) ensures consistent performance in industrial settings with fluctuating power supplies, while the 175W power consumption balances performance and energy efficiency.
The fan features a 190mm fiberglass-reinforced polypropylene impeller with 7 backward-curved blades, maximizing air displacement efficiency while minimizing noise (73 dB(A)). This design prioritizes static pressure over sheer airflow volume, making it superior to axial fans in applications where air must overcome significant resistance. The lightweight yet durable impeller also reduces motor strain, extending the fan’s overall lifespan.
With native support for both 0~10VDC and PWM speed control, the fan offers flexible airflow adjustment to match specific application needs. The FG (tachometer) output provides 4 pulses per revolution for real-time speed monitoring, and no external pull-up voltage is required—simply connect to monitoring systems for seamless integration. The pre-installed bracket enables tool-free mounting in any orientation, reducing installation time and effort.
Rated IP44, this waterproof centrifugal bracket fan resists dust and moisture, making it suitable for use in harsh industrial and semi-outdoor environments. It operates continuously within a temperature range of -25℃ to 60℃, adapting to extreme cold and heat. The ball bearing construction ensures a 50,000-hour (L10) lifespan under standard operating conditions, and integrated protections (motor current limitation, thermal overload, locked-rotor protection) prevent damage from abnormal operating conditions.
Server blades, UPS systems, and power supplies often require high-pressure ventilation to overcome the resistance of dense components and filters. This centrifugal fan’s 782 Pa static pressure ensures efficient heat dissipation, protecting sensitive electronics from overheating and extending their service life.
MRI machines, diagnostic devices, and laser systems demand reliable, low-noise ventilation to maintain precision performance. The fan’s quiet operation (73 dB(A)) and high-pressure output make it an ideal choice for cooling critical medical equipment, where temperature stability is essential for accurate results.
CNC control cabinets, robotics, and PLC enclosures in industrial settings generate significant heat and require robust ventilation. The fan’s industrial-grade durability, IP44 protection, and continuous duty rating make it suitable for 24/7 operation in factory environments, ensuring uninterrupted performance of automation systems.
Electric vehicle (EV) battery thermal management and train electronics require compact, high-performance cooling solutions. This 85V DC centrifugal fan’s bracket-mount design and wide voltage range make it compatible with transportation systems, providing reliable heat dissipation to protect batteries and electronic components from extreme temperatures.
The fan’s high-static-pressure capability makes it ideal for high-precision fluid transportation applications, where consistent airflow is required to move fluids through narrow pathways or specialized equipment. Its durable construction and waterproof design ensure reliability in demanding fluid handling environments.
Yes, it features an S1 continuous duty rating and integrated thermal protections, allowing for uninterrupted operation in critical applications such as industrial automation and medical equipment.
Absolutely. Both control methods are natively supported via the yellow wire (see product manual Section 5), offering flexible airflow adjustment to match specific application requirements.
Centrifugal designs excel in high-static-pressure scenarios (e.g., pushing air through filters or dense components) by generating greater pressure to overcome resistance. Axial fans, by contrast, prioritize high-volume, low-pressure airflow, making them less effective in resistance-heavy environments.
No—unlike EC fans, this DC centrifugal fan’s FG output is self-powered. Simply connect it directly to monitoring systems for real-time speed tracking without additional components.
The ball bearing construction minimizes maintenance needs. To ensure optimal performance, keep the fan free from dust buildup and avoid direct water exposure (consistent with its IP44 rating). Regular visual inspections are recommended to check for debris or damage to the impeller.
