Our centrifugal blower - backward curved fan comes in two types, namely, SISW (single inlet single width), and DIDW (double inlet double width). These fans have basically backward curved impellers with backward curved blades, having special profile to give maximum efficiency at low noise levels. These impellers are statically and dynamically balanced. These blowers are suitable for various applications where high volume air displacement is required. These are widely used for commercial and industrial ventilation.
