The FB3G190-110PS-90 is a high-voltage DC centrifugal fan built for extreme pressure demands. Its 190mm backward-curved impeller (glass-fiber-reinforced plastic) delivers 903m³/h airflow and 782Pa static pressure at 110VDC—perfect for compact, high-resistance systems. The brushless motor (BLDC92) ensures quiet, efficient operation across an 88–132VDC range.
High-Pressure Dominance
Achieves industrial-grade static pressure (782Pa)—equivalent to larger AC fans—enabling airflow through dense filters or narrow ducts in tight spaces.
High-Voltage Efficiency
Optimized for 110VDC systems, reducing current draw (1.6A) versus equivalent 24V/48V models. Broad voltage tolerance (88–132VDC) handles grid fluctuations.
RPM-Resilient Design
Glass-fiber-reinforced plastic impeller withstands 4300 RPM stress without deformation, while ball bearings ensure vibration-free operation.
Intelligent Safeguards
Integrates soft-start, reverse-polarity protection, and thermal cutoffs—critical for 175W high-voltage applications.
Industrial Dust Collectors: Pushing air through HEPA/carbon filters.
Laser Cutting Machines: Cooling optics in confined chambers.
3D Printing Enclosures: Ventilating high-temperature polymer fumes.
Laboratory Equipment: Fume extraction in chemical hoods.
Electric Vehicle Chargers: Thermal management in compact cabinets.
Q1: Why 110VDC instead of standard 24V/48V?
A: Higher voltage reduces current draw for the same power (175W), minimizing wire heating and enabling longer cable runs.
Q2: Can it handle 4300 RPM continuously?
A: Yes. The glass-fiber impeller and ball bearings are engineered for sustained high-RPM operation (50,000+ hours L10).
Q3: Is wiring different for 110VDC?
A: Use thicker gauges for long runs. Always follow the color code: red (+110V), yellow (PWM), white (FG), blue (GND).
Q4: What if my power supply fluctuates?
A: Works down to 88VDC and up to 132VDC. Outside this range, undervoltage/overvoltage protection engages.
Q5: Can I mount it vertically?
A: Yes. Supports any orientation (IP44-rated), but avoid directing airflow upward against gravity for optimal performance.
