Product Overview
The 48V-DC 355mm 320W External-Rotor Centrifugal Blower Fan integrates motor and impeller into a compact external-rotor unit. With a die-cast aluminum impeller, it delivers 810 Pa maximum static pressure and 3,230 m³/h airflow, targeting high-resistance systems like industrial ductwork or multi-stage filtration.
Features
External-Rotor Motor Design
Direct impeller drive eliminates intermediate components, ensuring efficient power transmission and reduced mechanical complexity.
High Static Pressure Capability
Generates 810 Pa static pressure to overcome dense filters, long ducts, or complex ventilation resistance while maintaining airflow stability.
Optimized Noise Performance
Operates at 71 dB(A) under full load, balancing power output with moderate acoustic impact for industrial environments.
Wide Voltage Tolerance
Supports 36-57V DC inputs, adapting to unstable power sources in off-grid or mobile applications.
Applications
Industrial HVAC: High-pressure air handling in factories, warehouses, or large commercial buildings.
Heavy-Duty Filtration: Pushing air through HEPA/carbon filters in manufacturing cleanrooms or exhaust systems.
Process Cooling: Ventilation for machinery, generators, or high-heat industrial equipment.
Ducted Systems: Overcoming resistance in extended or multi-bend ductwork.
