Efficient Airflow Solution for Compact Ventilation Systems
SZR's 100mm DC centrifugal fans are engineered for medium-volume cooling applications requiring concentrated airflow and stable pressure performance. The compact blower structure supports continuous heat dissipation inside confined industrial and electronic systems while maintaining low power consumption and operational stability.
Mechanical Structure
The fan frame adopts reinforced die-cast aluminum construction with anti-oxidation surface treatment for improved durability in industrial environments. The impeller is produced from high-strength UL94V-0 thermoplastic material to ensure dimensional precision and fire resistance.
Its centrifugal airflow design accelerates air through a side exhaust channel, helping improve cooling efficiency where axial airflow is insufficient. Internal balancing treatment minimizes vibration during high-speed operation and supports long-term thermal stability.
