Product Overview

The FK3G250-110PL-20 is a high-pressure centrifugal fan engineered for industrial systems requiring extreme static pressure performance. Featuring an integrated mounting bracket and 110VDC brushless motor (BLDC102), it delivers exceptional force (1,248 Pa) while maintaining precise airflow control. Ideal for demanding ventilation applications, it meets CE, RoHS, ISO9001, and ErP 2015 standards.

Core Features

  1. Ultra-High Pressure Capability
    Generates 1,248 Pa static pressure – the highest in its class – enabling ventilation in high-resistance systems like dense filtration or long duct runs.

  2. Wide Voltage Operation
    Operates reliably across 88–132 VDC, making it suitable for industrial environments with unstable power sources or custom voltage requirements.

  3. Bracket-Mounted Design
    Integrated steel support bracket simplifies installation and reduces vibration, allowing flexible mounting in confined or hard-to-reach spaces.

Applications

  • Industrial Dust Collection: Woodworking, metal grinding, powder handling systems.

  • High-Resistance HVAC: Cleanrooms, laboratory exhaust, HEPA-filtered systems.

  • Process Ventilation: Chemical fume extraction, industrial drying equipment.

FAQ

Q1: Why choose 110VDC over standard 24V/48V systems?
A1: 110VDC reduces current draw by 60%+ vs. lower voltages, enabling longer cable runs and compatibility with industrial power supplies.

Q2: Can it handle continuous high-pressure operation?
A2: Yes. Reinforced plastic impeller and ball bearings support sustained 1,248 Pa operation at ≤60°C ambient.

Q3: How is fan speed monitored?
A3: FG signal outputs 3 pulses/revolution – connect to controllers for real-time RPM tracking and fault detection.

Q4: Is the bracket corrosion-resistant?
A4: Standard bracket is steel. For corrosive environments, request optional stainless steel version.
