Teflon Nano Bearings (TNB)


Self-lubricating TNB are quieter than other fans because of their exceptional resistance to high temperature, vibration, and abrasion (MTBF 200,000 hours).



IP56 (Ingress Protection Rating)


High-level dust and water protected, resulting in an extended lifetime.



Noise Canceling Adapter


An extra cable converts the motor noise to silence.



Rubber Fixing Pins


Another option for securing your fan. Allows choices in customized cases or when screws aren’t needed.



Advanced 11-Blade Design
