T30C式軸流通風機是30K4-Ⅱ型的基礎上改進的，具有結構合理、風葉強度高、噪聲較小、效率較高等特點，本風機分為 普通型和開合型二種。主要用于氣體抽出或排送及其它不合油性、水性、塵埃氣體，所輸的為非易燃易爆，無腐蝕、無顯著粉塵氣體，介質溫度≤50℃，還可作為一般工業管道串聯加壓、送風和排氣之用。
T30c axial fan is improved on the basis of 30K4 - Ⅱ. It has the characteristics of reasonable structure, high blade strength, low noise and high efficiency. The fan is divided into ordinary type and open close type. It is mainly used for gas extraction or discharge and other non oily, aqueous and dusty gases. The transmitted gas is non flammable and explosive, non corrosive and non significant dust gas. The medium temperature is ≤ 50 ℃. It can also be used for series pressurization, air supply and exhaust of general industrial pipelines.
