T30系列轴流通风机是30K4-II型的基础上改进的，具有结构合理、风叶强度高、噪声小、效率高等特点，本风机分为普通型和开合型二种。主要用于气体抽出或排送及其它不含油、水、尘埃气体，所输送的为非易燃易爆、无腐蚀、无显著粉尘气体，介质温度≤50℃，还可作为一般工业管道串联加压、送风和排气之用。

　　T30A/C series are based on the type of 30K4-II and featured by rational structure, low noise, high efficiency, high blade strength and etc. The series consist of common type and open type, which are used for ventilation and pipeline compression in industrial pipeline, to supply and exhaust high temperature gas and gases with oil, water and dust. The gased should be non-flammable, non-corrosive with the temperature no higher than 50℃.
