Fully Sealed IP68 DC Fan for Extreme Moisture and Harsh Environmental Cooling
SZR's IP68 DC waterproof fan series is specially designed for electronic cooling applications requiring complete protection against water immersion, moisture penetration and corrosive operating conditions. The brushless DC motor structure combines high efficiency, low power consumption and long operational life, making these fans suitable for demanding environments including outdoor communication equipment, marine electronics and energy storage systems.
Product Construction
The fan housing adopts reinforced thermoplastic material with waterproof sealing treatment to ensure stable mechanical performance during long-term exposure to humid conditions.
High-precision fan blades are balanced dynamically to improve airflow uniformity and reduce rotational noise during high-speed operation.
The brushless DC motor integrates waterproof encapsulation technology that protects internal electronic components from water intrusion and condensation damage.
Sealed dual ball bearings improve operational stability while extending service lifetime under continuous industrial workloads.
