Safety
1. Take care that all the guards
 areincorrectpositionandxed
during operation.
2. Always stop the machine prior to
greasing, adjusting or repair.
3. Blower noise can be irritating.
Ear protection should be used
under long-term continuous
exposure.
4. Use eye protection when work-
ing in the vicinity of the intake
nozzle.Kernelscanyoutofthe
secondary air opening, causing
eye damage if proper protection
is not worn.
5. Avoid open suction pipes.
Clothing or objects can be
drawn into the machine and
cause injury to a person or
damage to the machine.
6. After conveying treated grain the
machine and the pipe system
should be carefully cleaned out.
7. Always use a discharge cyclone
to decelerate the grain and to
separate it from the air stream.
First Start-up
Instructions
1. All wiring must be made by a
certiedelectrician.
Min. fuse at 3 x 380 V
(recommended):
SUC 100E: 25 Amp.
SUC 150E: 35 Amp.
SUC 200E: 35 Amp.
SUC 300E: 63 Amp.
SUC 500E: 100 Amp.
2. Make sure that the direction of
rotation of blower and rotary
valve is correct (see arrows on
blower and rotary valve).
3. Check that the belt tension is
correct.
4. Make sure that all bolts are
tightened. Retighten the bolts
aftertherstdayofoperation.

Starting and Stopping
Starting
See that the slide of the suction
head is fully open or the suction
head removed from the grain be-
fore starting the machine.
Lock the air regulator of the blower
in starting position before start-up.
Release the pointer when the blow-
er has reached full speed (does
not apply to blowers provided with
air regulators closing automatically
during start-up).
Stopping
Stop conveying by removing the
intake nozzle from the grain or
open the slide on the intake nozzle
completely. Run blower and pip-
ing system clean - then stop the
blower.
Adjustment for maximum Capacity
Open the slide on the intake nozzle
fullu and place the end of the intake
nozzle in the grain.
Then slowly turn the slide on the
intake nozzle from the fully open
position towards the closed posi-
tion.
Just before the pointer of the
blower air regulator enters the red
area the suction hesd slide is
correctly adjustted.
The function of the slide is to en-
sure correct balance between air
and grain.
open
Closed
Start
Conveying
If the slide is open too far, there will
be too much air and too little grain
conveyed.
If the slide is closed too far, there
will be too little air and the grain will
settle in the pipe system, and may
block the pipe system completely.

Piping Instructions
Note: The poly-hose is designed
for clean-up only. For prolonged
operations of the blower use the
heavydutyexiblesteelhosesand
pipes only.
Use only one poly-hose in the
suction line. More poly-hoses will
reduce the conveying capacity
considerably.
Avoid connecting the poly-hose
directly to the suction cyclone. This
puts too much stress on the hose
and may cause a sharp bend re-
ducing capacity.
3. Keep the pipeline as short as
possible. Do not use more
bends and diverters than
necessary. This provides opti-
mum capacity and the gentlest
conveying.
4. Always use the OK160 dimen-
sions for the entire pipe system.
Even a short piece of either
bigger or smaller diameter will
reduce conveying capacity con-
siderably.
5. Air leaks between pipes will
reduce conveying capacity. This
is more important on the suction
line than on the pressure line.
Therefore, take care to avoid
leaks on suction line. It should
be recommended to use the
sturdy OKR clamps on the suc-
tion side.
6. If possible, all pipes should run
either horizontally or vertically.
Sloping pipes reduce capacity
and increase pipe wear.
7. Pipelines can be suspended in
long free spans but do not allow
these to exceed 4 m outdoors
and 5 m indoors without sup-
port.
2. Suction from a hopper:
 Usetheshortsuctionlineofexible
steel hose only. The highest capac-
ity is obtained if the intake nozzle is
placed as vertically as possible.
The capacity of the blower depends to
a large extent on the arrangement of
the pipe layaut.
The following points should be
observed:
1. Clean-up operations:
 Connectthetwoexiblesteelhoses
or a 45º bend and a steel hose to
suction cyclone and use the hoses
to bring the suction line uniformly
down to the ground. Then extend it
withrigidpipesandusetheexible
poly-hose just before the intake
nozzle.
45° bend

5
Selection of Intake Nozzle
Open the slide on the intake nozzle
completely, or raise the intake noz-
zle clear of the grain to see if the
blower itself can clear the system.
If this is not possible, separate and
empty the pipe system. Adjust the
slide on the intake nozzle for max.
conveying capacity.
Bin clean-up
The best procedure and sequence
for bin clean-up is normally to clean
onehalfrstandthentheother
half,asshowning.1-2-3.
Clearing a Blocked Pipe System
Use the correct intake nozzle for
your conveying job to ensure maxi-
mum conveying capacity and ea-
siest operation.

Maintenance
Warning
Always stop the machine prior to
greasing, adjustment or repair.
Greasing
SUC 100E, SUC150E, SUC 200 E,
SUC 300E:
All bearings are lubricated for life
and require no further greasing.
SUC 500E:
Grease the bearings on the blower
belt side every 200 working hours.
Use a lithium base grease of mini-
mum quality as Mobil Mobilux EP2
Belt Adjustment
Check V-belt tension regularly, espe-
cially when they are new. New V-belts
normally require adjustment after 15
minutes and again after 2- 3 hours
work.
Belt tension check
To inspect the V-belts remove the belt
guard. Use, for instance, a tension
tester to check the belts.
Order No.: 121 130 071.
Check the tension of all the belts. If it is
not possible to adjust one set of belts
so that all the belts have the proper
tension the whole set must be replaced.

with approx. 20 cm3= 20 g each
time. Never overgrease the bea-
rings.Ifthecasingislledwithtoo
much grease, the bearing will get
hot.
Cleaning
The screen inside the top of the
cyclone should be cleaned regu-
larly.
The material conveyed will determi-
ne how often cleaning is required.
If the screen is blocked the capacity
of the blower will be reduced.
Motors
Do not cover up the motors. Keep
them free of dirt reducing the coo-
ling.
Retightening
On a new blower all bolts and
screws are to be retightened after
therstworkingday.Apartfrom
that make sure that they are tight at
all times.
Storage
Clean and grease the suction
blower before storage.
To prevent rust, store the machine
in a dry place protected against
wind and moisture.

tion of 9.5 mm the force should be
between 3 and 5 kg.
Rotary valve:
Depressoneofthebelts.Atadeec-
tion of 3.5 mm the force should be
between 1.5 and 2 kg.
If the belts are too tight both the bearin-
gs and the belts will be overloaded and
their life considerably reduced.
If the belts are too slack they will slide
on the belt pulleys and wear quickly. At
the same time the blower will run too
slowly reducing conveying capacity.
How to use the tension meter
1. Position the lower rubber ring at
thedeectiondistanceonthelower
scale. Leave the upper rubber ring
against the the edge of the sleeve.
2. At center of span length apply force,
with tension tester perpendicular
to the span, large enough to make
thedeectiondistancecorrespond
to the edge of the adjacent belt. A
straight edge across the belts will
insure accuracy of reading.
3. Remove the tension tester and
 readthedeectionforceon 
upper scale, at the top edge of
the rubber ring.
4. If the force is too high, belts should
be slackened, and if the force is too
low, belts should be tightened.
Tightening of belts
Make sure that the belt pulleys remain
aligned during tightening. Check by
putting a straight board against the pul-
leys to see whether both pulleys bear
against the board.
The rotary valva will remain aligned
during belt tightening.

Trouble Shooting
Problem
Poor capacity
No capacity but
the blower is
working
Cause
Intake nozzle not correctly adjusted
Belts worn or need tightening
Air regulator cannot move freely
Pipe system not correctly arranged
Screen in cyclone blocked
Conveying air released from pressure side
builds up pressure in silo, hopper, etc.,
which lacks vent
Moist grain
Dirty grain
Rotary valve seals at side covers worn
Rubber blades in rotary valve worn
Wrong direction of rotation (see arrows on
blower and rotary valve)
Blocked pipe system
Rotary valve stopped due to a foreign ob-
ject jamming the drum
Rotary valve stopped due to a worn or
slack V-belt
Remedy
Adjust intake nozzle. See the paragraph
»Adjustment for maximum Capacity«.
Replace or tighten the belts.
The air regulator has not been released from
the starting position or its functioning is ham-
pered by dirt.
The pipeline should be kept as short as pos-
sible. Do not use more bends and diverters
than necessary. See also the paragraph
»Piping instructions«.
Unclip bend from the top of the cyclone and
clean the screen.
Open so that the conveying air may escape.
Whenmoistureishightheowrateispoor
and the capacity is reduced.
Duetoreducedowrateandlowerspecic
gravity the capacity is reduced when hand-
ling dirty grain.
Replace the seals.
Replace the rubber blades.
Ask the electrician to reverse the direction of
rotation.
Clear the pipe system. See the paragraph
»Clearing a blocked pipe system«.
Remove the object and check for damage to
the rotary valve.
Replace or tighten the V-belts. See the
paragraph »Maintenance«

Conveying Capacity
The conveying capacity depends
on the piping layout and the type of
material to be conveyed.
In the examples the conveying ca-
pacities apply to materials with the
followingspecicgravities:
Specic gravity
Material kg/m3
Barley .......................................670
Wheat .......................................750
Oats ..........................................500
Rye ...........................................700
Maize ........................................700
Rape .........................................700
Peas .........................................800
The capacities are based on pre-
cleaned material with a moisture
content of 15% (grain, maize and
peas) or 9% (rape). Unclean crops
and higher moisture contents will
reduce the capacities.
The tables on page 8 show the
conveying capacities for barley, rye,
oats and maize with three different
types of standard suction pipelines
and one standard pressure pipe-
line. The tables on page 12 show
corresponding capacities for wheat,
rape and peas.
Each table gives the capacities of
the different blower sizes at differ-
ent conveying distances.
The conveying distance is the total
length of all horizontal and vertical
piping on the suction and pressure
side. The length of suction hose
is included, but bends and suction
head are not taken into account.
If a long suction head is used, the
conveying distance must be in-
creased by 1.5 m. For each exten-
sion there will be a further increase
of 0.65 m.
Pneumatic conveying is based on
the use of atmospheric air to carry
the crops through the pipelines.
Thusfactorsinuencingtheair
condition (temperature, barometric
pressure) will also effect the con-
veying capacity. The capacities
shown are based on a barometric
pressure of approx. 760 mm Hg
and an air temperature of 20 C.
The examples given are only in-
tended as a guide as many other
factors may affect the capacity.

Principle of Operation
Intake nozzle
Suction side
Suction
cyclone
Blower Rotary valve
Pressure side
Discharge cyclone
The suction blower consists of a
powerful blower and a rotary valve.
Conveying is started by using the
suction air of the blower to lift and
accelerate the grain towards the
blower.
Just before the grain reaches the
blower housing it is separated
from this air stream in a cyclone
and dropped into the rotary valve,
whereas the air continues to the
blower. The rotary valve conveys
the grain from the suction side in
the cyclone to the pressure side in
the transport pipe.
Grain is carried to the outlet cy-
clone in air stream. In order to
secure a balance between air and
material, the suction blower is
equipped with an adjustable intake
nozzle.
Function and Use of Air Regulator
The blower is provided with an
automatic air regulator positioned in
the pipe between the cyclone and
the blower intake.
The purpose of the air regulator
is to limit the max air speed of ap-
prox. 25 m/sec. Thus grain damage
owing to excessive speed as well
as overloading of blower will be
avoided.
The air regulator is a spring-loaded
butteryvalve.Whenthebloweris
stopped the air regulator is com-
pletely open. When the blower is
startedtheairowwillclosethe
regulator so that the air speed does
not exceed approx. 25 m/sec.
When the back pressure drops, the
airregulatorwillclosesufciently
to prevent the air speed exceed-
ing approx. 25 m/sec. A typical
example is the variations in back
pressure which occur at clean-up
operations.
The air regulator will only be effec-
tive if the spring of the regulator is
properly adjusted. Therefore, never
adjust the spring unless the proper
equipment is used to check that
the ideal conveying speed is main-
tained.
If the spring of the air regulator is
too slack, max air speed will be
reduced and thus conveying capac-
ity will fall. At the same time there
is the risk of material settling in the
pipes and plugging could occur.
If the spring is overtightened, the
max air speed will be increased,
increasing risk of damage to the
product conveyed. Capacity will not
be increased but blower and trac-
tor will be under more load. Hence
belts and bearing of the blower will
be loaded in excess of what they
are designed for. Consequently,
their life will be considerably
shortened.
