HF-I轴流风机与HF-II多翼型可调轴流风机具有比一般轴流风机风量大、风压高等特点，可广泛用于工业管道加压、厂矿企业、民用建筑等通风换气，而HF-II的叶片、轮毂采用优化设计、叶型包铬造型，由优质铝合金精密压铸而成，具有高强度和一定的耐腐能力，可适用于环境不含易燃易爆气体、腐蚀性气体及介质温度不超过80℃中使用，风叶角度可任意调节。
Compared with the common axial fan, HF- I type axial fan and HF- II multi-blade adjustable axial fan have a larger air volume, a higher pressure and other features, which is widely used for ventilation in the mining factories, civil buildings and etc. In addition, the profile of HF-II is shape with chromium blade and the angle adjustment can be arbitrary. With the optimal design, the hub and the blades are casting from good quality aluminum alloy in precision, which allows high intensity and a certain ability to decay. HF- I / II are suitable for the places that don’t contain flammable, explosive and corrosive gases with the temperature no higher than 80℃.
