Product Overview
The 230V-AC 280mm 195W External-Rotor Centrifugal Blower Fan integrates an EC motor and glass-fiber reinforced impeller into a compact external-rotor unit. Designed for moderate-pressure applications, it delivers 452 Pa maximum static pressure and 2,517 m³/h airflow, targeting ventilation systems with standard resistance requirements.


Features
External-Rotor EC Motor
Direct impeller drive eliminates intermediate components, ensuring efficient power transmission and reduced mechanical complexity.

Balanced Pressure & Airflow
Generates 452 Pa static pressure to overcome resistance in ductwork or filtration systems while maintaining consistent airflow.

Optimized Noise Control
Operates at 71.5 dB(A) under full load, suitable for commercial or light industrial environments.


Applications

  • Commercial Ventilation: Air handling in retail spaces, offices, or small workshops.

  • Light Industrial Exhaust: Fume extraction or cooling for machinery with moderate resistance.

  • Filtration Support: Pushing air through standard filters in purification or HVAC units.

  • AC-Powered Equipment: Integration into systems requiring reliable 230V operation.
