Blower units and axial blowers
PRESENTATION OF THE 5.5 kW, 7.5 kW, 11 kW and 15 kW RADIAL
BLOWER UNITS
Blower units are available in four sizes. A model equipped with a 5.5 kW or a 7.5 kW motor. The external dimen-
sions of both models are the same, but their weight is di󰀨erent.
As well a model with a 11 kW motor and a model with a 15 kW motor. The external dimensions of both models
are the same, but their weight is di󰀨erent.
- The blower unit comprises a blower and a base. In addition, in the delivery is included a conversion part between
the blower and the pipe, exible bellows on both sides of the blower, an air amount adjuster and the required
bolts and bands.
- Blower units are available with both left-handed and standard handedness with pipe outlets of either D630 or
D800, see the table below presenting our number for the item and, further down, the handedness.
- If the pipeline is long or there are several elbows, we recommend pipe-size D800 for the 15 kW blower units.
This way it is possible to prevent unreasonably high pressure loss in the pipe.

CHANGING HANDEDNESS OF THE 5.5 kW AND 7.5 kW BLOWER MODELS
Fig. 1.
Fig. 3.
Fig. 2.
Fig. 4.
The handedness of the 5.5 kW and 7.5 kW blower models can be changed. This is achieved by switching places
of the blower legs. These instructions illustrate how to convert a standard (right-handed) blower to a left-handed
one. Also the rain cover must be transferred to the other side.
1. Turn the blower against the oor. Remember to put pieces of wood under the blower chamber to make
the legs easier to remove and prevent the blower from breaking. Fig. 2. Remove the legs from the
blower chamber.
2. Fig. 3. Fix the legs on the other side of the blower chamber as illustrated. Fix the bolts carefully and
wrench them tight. It is vital that also the xing bolts for the side supports are put back in place. (en-
largement in Fig. 4)
3. Fig. 4. You can lift the blower upright as soon as the legs of the chamber have been xed. Remember
to put the xing bolts for the side supports back in place.
4. Note!Fig. 4: Also the motor cover must be transferred to the other side. This is achieved by removing
the motor cover with its support irons (2 pcs.) The picture illustrates how to x the motor cover and the
support irons.

NOISE EMISSION OF THE BLOWER UNIT
NOTE! Always use hearing protectors near the blower units while the suction fans are in operation.
- Measuring point at a distance of 1 m from the suction opening of the blower unit L Aeq 92 dB
- Measuring point at a distance of 10 m from the suction opening of the blower unit L Aeq 75 dB
WEIGHT OF THE BLOWER UNITS

- Blower unit 7.5 kW 177 kg
- Blower unit 11 kW 267 kg
- Blower unit 15 kW 295 kg
FLEXIBLE AIR PIPE PART
Put a exible part between the blower and the piping in both the suction and pressure connectors. This prevents
possible vibrations from passing on to the piping or heavy loads created in the piping from passing on to the blower
unit. So the piping must be supported and the exible part must not be subjected to any excess load resulting from
the weight of the piping.
INSTALLATION
The blower unit is heavy and because of possible vibrations resulting from its unbalance, it must be placed on a
rm base. The blower unit must always be attached to its base using bolts.
The air amount adjuster of a radial blower can be located either between the dryer and the blower or in the pipe
on the pressure-side of the blower.
NOTE! The adjuster must never be located in the pipe between the heater and the dryer.
The blower delivery also includes a protective net which must be removed before connecting a pipe either before
or after the blower. Any net installed will gather dirt and you must be able to clean it regularly.

PRESENTATION OF 17,2 kW and 8,66 kW AXIAL BLOWERS
The blowers are available in two di󰀨erent sizes. Those are equipped with either a 17.2 kW or a 8.66 kW motor.
The blower shall be installed outside the dryer, inside the air channel.
The motors are by one size smaller than stated in the nameplate, but the given output, however, is correct. Run-
ning at a greater load is possible, provided that the cooling e󰀨ect is su󰀩cient.
- The delivery of the axial blower includes a suction bell, to be installed as shown in the drawing, taking note of
the installation practice applied.
- Also a re thermostat is delivered with the blower. There are installation points for both the re thermostat and
the outlet temperature sensor in the blower frame.

SERVICING
The cooling ribs and the impeller blades of the electric motors of both radial and axial blowers must be cleaned. If
the cooling ribs get dirty or the blower starts vibrating because of dust accumulated on the impeller, the cleaning
may have to be repeated even during the operating season. In addition, we recommend keeping an eye on the
essential parts of the blower for any signs of corrosion/fatigue and on the screws for tightness.
ELECTRIC INSTALLATION; FIRE THERMOSTAT
- Ensure the correct direction of rotation of the blower.
- Carry out the electric connection of the heater in accordance with the wiring diagrams for the electric centre.
- Install the re thermostat.
The re thermostat shuts down all the operations of the dryer immediately after the pre-set temperature has been
reached, for example, as a result of re inside the dryer. The re thermostat is delivered with the blowers. A re
thermostat is installed in every outlet pipe from the blower. Normally the thermostat is adjusted to 60 °C. The ther-
mostat comes with a 2-metre-long capillary pipe, which makes it possible to install the thermostat box in a location
where it is easy to access. The manually operated reset button at the side of the thermostat box must always be
reset after the temperature has risen to the switch-o󰀨 limit. In normal operation the temperature never rises to
such a high level. Such an exceptional situation may occur while the dryer is being test run empty whereupon the
temperature may easily rise to the pre-set switch-o󰀨 value.
