The instruction for AC fan

The frame of AC fan is Durable-cast Aluminum ,and the impeller is PBT (Thermoplastic  black Ul-94-VO),There are two kind of bearing system: ball and sleeve. Clients can choose the bearing system according to their requirement. Jianzhun  fan widely applies to accurate apparatus,generating equipment,warm-air blower,electric welder. Before leaving factory, jianzhun fan is strictly tested(including dielectric strength,moisture-proof,cold resistance,thermostability,impact strength,longvity experiment,etc.)It can be used safely.
