Single Width Single Inlet (SWSI) fans are most commonly used when suction duct is required on the fan inlet. The single width fan has the advantage of providing a connection from the duct directly to the fan inlet, without the use of inlet boxes. Single inlet single width fans (SISW) are used mainly for handling Clean Air and for high capacity and low pressure applications.

The product features aerodynamically designed casings and inlet cones, low noise levels and impeller design that allows for air expansion over the entire blade width, with relatively low velocity and minimum turbulence resulting in superior performance.
