- PREMIUM DURABILITY: A Loop Dynamic Bearing (LDB) with sealing is rated at the highest dustproof level of IP6X and includes a performance lifespan of up to 160,000 hours and 5-year warranty
- SMART FAN ENGINE: Low starting voltage reduces power demand, while an intelligent jam detection sensor with auto-resume functionality protects the blades against damage when obstructed
- ANIT-VIBRATION SCREWS: Secondary noise output caused by frame mouting is virtually eliminated with the included 4 rubber anti-vibrarion screws
