通风器直销电话【1】通风器节能环保        安全可靠　　本产品不用油不用电，无须维修，安装简单。只需3.2公里/小时的微风或室内外温差超过3摄氏度即可全天侯运转，并能达到通风换气之目的。        设计精密　坚固耐用　　通风器的主材全部采用韩国蒲金生产的304#不锈钢为原材料，通过模具一次冲压成型，核心部分采用双密封特制哈尔滨轴承，铝铸支撑。确保不锈钢屋面通风器的使用寿命达20年以上。        车间厂房应用　功能齐全　　通风器应用于车间、厂房时，除可有效排除室内的蒸汽、湿气、废气、烟雾、化学气味和粉尘等有害物质外，还可以配合消防的需要，为工作人员创造一个舒适、清新的工作环境。        住宅应用　效果显著　　通风器应用于别墅、住宅楼时，会使排风道内产生负压效果，并形成较强的抽取效应，能彻底清除厨房、卫生间的异味，并避免上下楼        的窜味、窜烟排气不畅等弊病，为屋室创造一个清新、舒适的居住环境。        防结露、防雨水　　风机全天候运转，能有效降低室温，并能防止冬天室内屋顶结露，且运转时会产生离心力，雨水绝对无法渗入INOX—304#抛光不锈钢板叶片材质特点：              
1、        进口304#抛光不锈钢板制作的叶片具有优良的不粘性和自洁性；              
2、        外观明亮、持久如新；              
3、                抗碱抗腐蚀酸性强，耐磨损，不生锈等。机压一体成型弧形双峰波纹叶片更加坚固。              
——普通通风器叶片的性能差异              
免电力通风器最关键的是确保不渗漏雨水，不变形，全天候正常顺时针方向运转，抵抗台风和沙尘暴。要达到以上目的最关键是叶片的设计。目前市场上出现的免电力通风器其叶片是采用两
