Product Overview
The FK3G310-2AAL-20 is a high-pressure AC centrifugal fan engineered for industrial cooling in space-constrained applications. Featuring a 310mm aluminum impeller and 102mm EC motor, it delivers exceptional static pressure with optimized energy efficiency. Designed for continuous operation (S1 duty) with IP54 protection, it supports advanced control protocols for demanding environments.


Key Specifications

  1. High-Pressure Dominance: Generates 888 Pa static pressure (45% above standard 310mm fans) to overcome dense filtration systems or compact ductwork.

  2. Optimized Power Efficiency: Operates at 230VAC with wide voltage tolerance (184–270VAC), reducing current draw by 25% vs. comparable 380VAC models.

  3. Smart Control Integration: Features RS485/MODBUS communication alongside 0-10VDC/PWM inputs and 5-pulse tachometer output for automation compatibility.

  4. Acoustic Performance: Maintains 80.4 dB(A) noise levels at 2826 m³/h airflow – 15% quieter than industrial benchmarks.


Applications

  • Industrial Machinery Cooling: High-static-pressure ventilation for CNC equipment and laser cutters

  • Commercial Kitchen Exhaust: Hood systems requiring >800 Pa static pressure

  • Medical Imaging Equipment: Thermal management for MRI/CT power cabinets

  • Packaging Machinery: Drying/cooling stations with space limitations
