for example, from Ø150mm to Ø120mm, first reduce from Ø150 to Ø135, use a straight section 0.5-1m
long of Ø135 and then apply a second reduction from Ø135 to Ø120mm
.
Ø150 Ø135 Ø120
(c) Do not place curves or bends just before or after a reduction .

smooth as possible, in the case of flexible conduits, stretch them out well so the corrugated walls are as
smooth as possible, this will improve suction as well as reduce noise levels
.
