Blowing direction
Do not attempt to blow grain downwards, where gravity
will add to the conveying speed. Damage to the grain
and pipes (bends) will occur due to the high speed.
Flexible piping
Do not attempt to blow through flexible down pipe
sections. Damage to the grain and to the flexible pipe
will occur.
Supports
The pipe line shall either be supported or suspended
at a distance of max. 4 metres. Furthermore, it is re-
commended to support the pipe as close to the bends
as possible.
Connections and centering
When connecting the pipes, bends and other material,
which are designed for high speed conveying , it is
important to center the pipes as precisely as possible
at the connecting points.
Right
OK160 clamp
OK160 pipe
Do not rely on centering the pipe with the clamps
alone. The clamp is designed for pressing the OK-pipe
ends very hard together in order to ensure a very high
tightness. This causes the friction between the pipes to
become so high, that the clamp is unable to center the
pipes. Check gap between clamp and pipe to ensure
it is similar on both sides. Check the pipeline visually to
secure a straight line.
If the pipes are not centered, the wear on the connec-
tion result in a fast wear out.
If a completely tight connection is required, the conne-
ction can be winded with sealing tape before installing
the clamp.

Cyclones
When installing a cyclone in the pipe system, it is im-
portant to obtain the right entry angle.
Min. 1 m
Right
Do not install a bend turning in the opposite direction
of the cyclone right in front of the entry. If this is done,
the effect of the cylone is more or less neutralized.
If it is necessary to install a bend prior to the cyclone,
it shall bend in the same direction as the cyclone, or
a straight pipe of minimum 1 meter must be installed
between them.
OKD downpipe material
Do not use OKD downpipe bends and diverters in a
pneumatic conveying system. Down pipe components
are not airtight, resulting in loss of capacity and da-
mage to the grain.
