Sunon fan 12V DC series EB/EE/LFI/MB/MF/HA 

4-pole DC fans are designed to provide efficient and reliable cooling for various applications. These fans feature impellers and frames made of filled thermoplastic PBT (UL94V-0), which ensures durability and resistance to high temperatures. The magnetic levitation system further enhances the performance by reducing noise levels, increasing airflow, and extending the lifespan of the fan. They have a choice between three different bearing systems: sleeve bearing (EE_S_), ball bearing (EE_B_), or vapo bearing system (HA_, M_). This allows users to select an option that best suits their specific needs in terms of noise level, speed range, operating temperature range, etc.
