EXPANSION SECTION - D

When an element requires a uniform air ow (for example noise suppressors, lters), then between this
element and the fan an expansion section - D should be installed. This section is equipped with
diaphragm made of perforated sheet, to ensure a laminar prole of air ow. In well cases this solution
can be also used on the suction side of Plug-type fans.
