Detailed Product Description

Advanced EC Motor Technology for Industrial Efficiency

The SXDOOL 70mm EC Cooling Fan integrates electronically commutated (EC) motor technology, combining AC voltage input with DC-driven performance. This hybrid design ensures linear energy consumption relative to speed adjustments, unlike inefficient AC fans that spike in power usage under load variations . With an operational voltage range of 90-270V AC, this fan guarantees stable airflow (27.6 CFM) in diverse electrical environments, from North American 115V to European 230V systems .

Durability Engineered for Demanding Applications

Featuring dual ball bearings, this fan outperforms sleeve-bearing models with a 50,000-hour service life—equivalent to over 5 years of non-stop operation. The IP65-rated construction (upon customization) protects against humidity and particulate ingress, making it suitable for harsh settings like factory floors or food storage units . Its reversible rotation capability allows flexible airflow direction for intake or exhaust configurations .

Optimized for OEMs and System Integrators

As a leading industrial cooling fan manufacturer, SXDOOL provides OEM-ready solutions with modular designs. Customize blade angles, motor windings, or housing materials to match specific static pressure requirements or noise limits. Compliant with international standards including CE, RoHS, and UL, our products ensure seamless integration into global supply chains .
