High-Airflow EC Cooling Fan for Industrial Ventilation Systems
SZR's 120mm EC axial fan series is engineered for medium-scale thermal management applications requiring balanced airflow efficiency, intelligent speed regulation and reduced power consumption. The electronically commutated motor design improves operational stability while maintaining lower heat generation during long-term continuous service. These fans are widely applied in telecom cabinets, inverter systems, industrial control enclosures and energy storage equipment.
Product Construction
The external frame adopts reinforced die-cast aluminum with anti-oxidation coating to improve structural rigidity and corrosion resistance in industrial environments.
Fan blades are manufactured from UL94V-0 certified thermoplastic material, providing excellent dimensional accuracy and thermal endurance under elevated operating temperatures.
The EC motor integrates electronic control circuitry that supports efficient variable-speed operation and lower electromagnetic interference compared with conventional AC fans.
Optimized blade geometry improves airflow concentration while reducing rotational turbulence and operating vibration.
