The first-stage impeller rotates clockwise, the second-stage impeller rotates counterclockwise, and the air enters the first-stage impeller from the collector to obtain energy and then directly enters the second-stage impeller, and is sent out after being pressurized. The role of the secondary impeller, in addition to increasing the airflow energy, also has the function of static guide vanes in other types of axial flow ventilation. Noise is reduced. https://www.hengdingfan.com/Content/upload/video/202217923/video202211021400546106415.mp4 2019-05-11T15:21:49+08:00 yes no https://www.hengdingfan.com/mining-fan/boiler-centrifugal-exhaust-and-induced-draft.html https://www.hengdingfan.com/uploads/202217923/small/boiler-centrifugal-exhaust-and-induced-draft11277115391.png Howden Axial Fan Howden axial fan, it can transport air and other gases that do not spontaneously ignite, are harmless to human beings, and are not corrosive to steel.
