GDF型离心式管道风机是在吸取技术的基础上加以改进，自主研制的新型产品，风机静压高、运转平稳、噪声低、安装尺寸小，方便安装，可直接与风管连接，广泛用于工业与民用建筑内的通风换气。输送空气和其他无腐蚀、无粘性物质对人体无害的气体，所含尘土及硬质颗粒物≤120mg/m³，气体温度范围-20℃-60℃。

GDF centrifugal duct fan is a new type of product independently developed on the basis of absorbing foreign advanced technology. The fan has high static pressure, stable operation, low noise, small installation size and convenient installation. It can be directly connected with the air duct. It is widely used for ventilation in industrial and civil buildings. Transport air and other non corrosive and non viscous substances harmless to human body, with dust and hard particles ≤ 120mg / m ³， Gas temperature range - 20 ℃ - 60 ℃.
