YWF Series External Rotor Axial Fan (Square)
| Product | YWF Series External Rotor Axial Fan (Square) |
| Category | Refrigeration Fans |
| Description | The YWF series external rotor axial fan is developed by Jiayi Fan with technical strength from many domestic universities, featuring high efficiency, low noise, low vibration, compact structure and beautiful appearance. The impeller is fixed directly on the motor outer circle for a short axial dimension — reaching the international advanced level. The square type (FA) uses a square frame structure for flexible installation, especially suited to cooling support for refrigeration equipment, condensers and evaporators, and can also be used in kitchens, mines and other places with serious oil, smoke and dust. Blade diameters cover 200–600mm with single/three-phase and 2/4/6-pole motors, airflow of 510–13000 m³/h and 220V/380V voltage, replaceable for conventional axial fans. |
