Lubricant Free. Operation in extreme temperature from -40 to 100 degree Celsius guaranteed!
In 60 degree Celsius operation environment, traditional ball-bearing and sleeve-bearing fans are likely fail due to thermal expansion contraction and lubricant dry out. In contrary to traditional bearings, Nano technology needs no lubricant. Nano fan passed rigorous test and operating 4 hours under 100 degree Celsius environments and no worries for lubricant leak or dry-out. The Nano bearing shaft has low expansion coefficient and runs smoothly in tough environment conditions.
Remark: -New production uses lubricant for easy assembling parts. Nano fan does not require lubricant. -Test setup compliant to MIL-STD-202
Waterproof, Dust-proof (IP 5 / 6)
Because there's no lubricant needed, Nano fan is both water and dust proof and compliant to EN60529: 1991-IP5X (dustproof test) and EN60529: 1991-IPX8 (water proof test).
Nano fan can be dissembled for wash and making it always stays in best condition, yielding low noise and maximizes air flow. Even the traditional ball-bearing fan with dust and water treatment, it is likely to fail due to excessive friction between the dust and rust, and lubricant leakage.
