Figure 38: Pipe designs
Change of direction in the pipe system can increase the flow resistance.
Light change of direction (e.g. with 90 ° pipe bends or air sampling hose) are
already approved as part of the project according to EN 54-20 or ISO 7240-
20 and need not be considered further.
If the pipe system includes 90 ° angles, the maximum overall length of the
pipe system will be reduced. In this case, a 90 °-angle corresponds to a
straight pipe length of about 1.5 m air sampling pipe.
