YWF Series External Rotor Axial Fan (Low Profile)
| Product | YWF Series External Rotor Axial Fan (Low Profile) |
| Category | Refrigeration Fans |
| Description | The YWF series external rotor axial fan is a new product developed by Jiayi Fan combining technical strength from many domestic universities through repeated research and trial production. Compared with conventional axial fans, it features higher efficiency, lower noise, lower vibration, compact structure and beautiful appearance. The impeller is fixed directly on the outer circle, making the axial dimension shorter — a major breakthrough reaching the international advanced level. Thanks to high efficiency, low noise, low vibration and short axial size, it can replace conventional axial fans and is also suitable for kitchens, mines and other places with serious oil, smoke and dust. The low-cylinder (A type) structure is compact for space-limited installations. Blade diameters cover 200–600mm, with single/three-phase and 2/4/6-pole motor options, airflow of 510–13000 m³/h and 220V/380V voltage. The clear model naming (e.g. YWF2D-400S-5L) makes selection easy. |
