全金属机体设计，静电喷涂，耐高温、不易生锈。金属合金风轮与高质防热电机配合使用实现了大风量，超静音。安装维修方便，隐蔽机体，实现超低静音。
Designed entirely with metal and sprayed by static electricity,it’s able to bear high temperature and rustiness-resistant.In order to produce mass wind but super sound, it combines alloy wheel with high quality heat-proof electric moter to work. With hidden enginery and litter volice, it’s convenient to fix and maintain.
