Yuanxiang YSWF series external rotor axial fan is engineered for air compressor cooling systems, providing reliable forced-air cooling across oil coolers and aftercoolers. Available in impeller diameters from 200mm to 710mm with power ratings from 90W to 1500W, these fans feature a compact external rotor motor design that eliminates belts and external bearings. The axial flow configuration delivers high air volume with low noise, maintaining stable airflow even against system resistance. Constructed with a die-cast aluminum or steel housing and dynamically balanced impeller, the YSWF series operates on AC 220V single-phase or 380V three-phase power. Typical models such as YSWF102L35P4-522N-450B deliver 4000-5000 m³/h airflow at 1360 RPM, making them a direct-fit replacement for many Atlas Copco, Ingersoll Rand, and Sullair compressor cooling applications. With IP54 protection and Class F insulation, these fans are rated for continuous duty in demanding industrial environments.
