Large-Airflow Cooling Solution for Heavy-Duty Equipment
SZR 225mm DC centrifugal fans are developed for large-scale thermal management systems requiring high airflow capacity and stable pressure output. The blower design supports industrial ventilation environments where continuous heat extraction and durable operation are essential.
Structural Composition
The housing adopts reinforced metal construction with anti-corrosion coating treatment for improved mechanical strength. The fan wheel is formed from durable flame-retardant engineering polymer material to ensure balanced high-speed performance.
Its optimized centrifugal air channel structure improves airflow concentration while reducing internal resistance. The motor assembly incorporates precision balancing technology to maintain smooth and stable operation under heavy-duty workloads.
