Product Overview

The FK3G280-2AAL-30 is a high-performance industrial centrifugal blower designed for demanding ventilation applications. Combining a 280mm die-cast aluminum impeller with a 700W EC motor, it delivers 3,621 m³/h airflow and 952 Pa static pressure—ideal for systems requiring robust airflow against significant resistance. Operating on 230V AC (184-270V range), it excels in industrial settings where reliability and smart control are critical.


Core Characteristics

  1. Industrial-Grade Power & Durability

    The die-cast aluminum impeller withstands high-RPM operation (2,900 max) in abrasive environments like metalworking or wood shops. Class F insulation allows sustained use near heat sources (up to 115°C), ensuring longevity in foundries or boiler rooms.

  2. Precision Monitoring & Control

    Features a 5-pulse/revolution FG tachometer—delivering 2.5× more RPM data than standard models—for real-time performance tracking. Combined with 0-10V/PWM speed control, it enables predictive maintenance (e.g., detecting airflow drops before system failure).

  3. Smart Factory Integration

    Integrates RS485 MODBUS (RSA/RSB ports) for seamless communication with building management systems. Monitor energy use, adjust airflow remotely, or receive instant alerts via NC/COM alarm contacts during faults—reducing production downtime.

  4. Plug-and-Play Resilience

    Handles 184–270V AC voltage swings common in aging industrial grids. The IP54-rated housing protects against dust and water splashes, suitable for harsh workshop environments.


Typical Applications

  • Factory Fume Extraction: Removing welding smoke or chemical vapors in manufacturing cells.

  • Industrial Oven Cooling: Ventilating high-temperature processing lines near furnaces.

  • Large-Scale Dust Collection: Powering central systems in woodworking/metal grinding facilities.

  • Smart Facility Upgrades: Retrofitting legacy ventilation with MODBUS-enabled predictive maintenance.
