SI-Back A fans are designed for installations requiring large air deliveries with relatively low pressures, in duct mounted applications. For instance: ventilation and conditioning of industrial and commercial plants, car parks, marine and mining applications, etc.
This line consists of 15 sizes with impeller diameter from 250 up to 1250 mm.
SI-Back A line is characterized by the extreme sturdiness due to the rigid construction in enamelled sheet metal and the thickness of the materials. Another feature is the variety of models and versions composing the series, consenting to find the suitable solution for many ventilation problems. Impeller is available in different classes (I-II-III) according to the maximum RPM admitted for the relevant diameter.
