GF4-72型(C式)玻璃钢离心通风机
GF4-72(C式)型玻璃钢离心通风机采用聚脂玻璃钢材质，它具有强度高重量轻、耐腐蚀性能良好不易老化、噪声低等特点，是较理想的新型防腐蚀风机，叶轮采用水冷座或油冷座经角带与电机传动。其好处是减少腐蚀电机、减速、降低电机负荷等作用，从而增加风机使用寿命

GF4-72 (type C) FRP centrifugal fan
GF4-72© type glass steel centrifugal fan using polyester FRP material, it has the advantages of high strength, light weight, good corrosion resistance, not easy ageing, low noise chaacteristics, is a new type anti-corrosion fan ideal, impeller using water or oil cooled by a seat belt angle and transmission electric machine. Its advantage is to reduce the effect of corrosion motor, decelerate, reduce motor load and so on to increase the service life of the fan.
