1. Purposes:
4-72 type centrifugal fan as a general factories and large buildings with indoor ventilation, and air and other transportation is not spontaneous, harmless to the human body, not corrosive to steel gas. B4-72 fan can be as volatile flammable gas ventilation use. Gas is not allowed within the viscous substances contained dust particles and rigid, not more than 150 mg / m 3.
B4-72 fan of the performance and selection of 4-72 and consistent with the size of the foundation, according to their choice. Fans of the basic structure of the same type with 4-72, motor selection and the corresponding Y Series YB series.
2. Features: Air good performance, high efficiency and smooth operation.
