Direction change
90° angles and bends (elbows) increase flow resistance. They are there-
fore to be avoided as much as possible.
90° swept bends should preferably be used, as 90° elbows have a high
flow resistance. So 90° elbows should only be used where they cannot
be avoided because of structural restrictions.
equivalent straight pipe length
90° elbow
1,5 m
90° swept bend
0,3 m
If 90° elbows or swept bends are used, the maximum overall length of the
pipe system is reduced.
90° swept bends are to be preferred over 90° elbows.
Too many changes in direction will seriously influence the detection
time.
Special cases
If because of structural restrictions the pipe system does not correspond
to the design guidelines given here, each case must be calculated sepa-
rately by WAGNER.
Checking
In critical applications, check there is safe detection by carrying out simu-
lated smoke tests (see chapter 7.5). Check also for proper suction pres-
sure at the individual aspiration holes.
To increase the transport speed in the pipe system in critical areas, the
fan voltage can be raised in steps from 9 V (Standard) to 13.5V.
