Cyclones
When installing a cyclone in the pipe system, it is
important to obtain the right entry angle.
Min. 1 m
(3.3 ft)
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 m (3.3 ft) must be installed
between them.
Back-pressure
If material is being blown into for example a container
with inadequate air outlet the back pressure will reduce
Pipe layout
Direction of pipeline
Keep the pipeline horizontal or vertical. Longer sloped
rising or falling distances will result in wear on the
pipes, risk of plugging of pipes, damage to the material
and capacity loss. The only time sloping pipe layout
is advisable is right before the material reaches its
destination.

the conveying capacity. Open the container to allow air
to escape.
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
damage to the material.

Conveying to two or several difficult accessible
destinations
When conveying grain through areas, where service
is difficult, e.g. high silos, it can be considerably less
expensive long term to use several separate pipelines,
as in example 1. Investment is slightly more expensive
than example 2, but it is normally easier and less
expensive to make service on this plant, and wear on
the pipes is reduced considerably, becausen not all
grain for both silos should pass through the same pipe.
