IMPORTANT - Please study all the instructions
before mounting and commissioning.
Please keep these instructions in a safe place and
instruct all users in the function and operation of
the product.
Do not dismantle any factory-mounted parts, since
it impedes the commissioning of the equipment.
1.1 Danger
Explosive media –The Fan is not suitable for the
extraction of aluminium dust, flour, textile dust nor
for sawdust or other media, which are connected
with danger of explosion, without specific approval
from Geovent A/S.
Removing the protection net on the fan whilst in
operation involves a risk of mutilation.
Always switch off the current when mounting
something on the Fan or when servicing it.
1.2 Field of application
The GEOVENT transportable Fan PM-225 is
typically used for comfort ventilation as well as for
smaller process extraction jobs, where a high
pressure is not required. The Fan is applied for
process extraction within the industry for the
extraction of welding smoke, vapours, and other
jobs where a fixed installation is not possible
GEOVENT PM-225 may NOT be started
without the hose mounted, since this may
result in motor overload.

The sound level depends on various factors under
various circumstances. For instance, where in the
room the Fan has been installed, the size of the
room, the temperature in the room, the sound of
the room and also the connection (hose><pipe) of
the Fan influences the sound level of the Fan.
The actual ampere consumption and the kW of
the motor are shown on the metal sign on the
Fan.
1.4 Construction
Fan housing: 100% hot-galvanized steel for
optimal corrosion resistance. Carrying feet have
been mounted on all Fans with fitted vibration
dampers as well as inlet nozzle with safety net.
Fan wheel: Forward curved sirocco-fan wheel (F-
wheel) in hot-galvanized steel sheet.
Motor: B5 flange motor, directly driven in
protection class IP 55.
Shield Powder Coated

Hose/hood 2x5m ø200mm flexible and lightweight
hose with coupling brackets for easy mounting
and dismounting. Power coated extraction hood
with 1 strong power magnet.
Cable 10m rubber cable, 16A CEE plug.
2.0 Installation
The Fan is supplied in complete/assembled
condition, ready for connection to piping and to
the mains.
If at all possible, please avoid bends just before
the intake and after the outlet, since otherwise this
would reduce the yield of the Fan.
Connection of the Fan to the mains:
1. The Fan should be connected to 3x400V
50Hz, as standard.
2. Circuit diagram 3-phase motor (non-
adjustable). Should only be changed by
qualified electrician, in case the direction of
the impeller is wrong.
3.0 User instruction –application
When extracting large quantities of air, containing
dust, the fan wheel may get out of balance due to
dirt on the wheel.
In many cases, the Fan is started by pushing the
green button on the motor protection switch (if
automatics are not used).
The Fan does not work according to the purposes,
if …
- unauthorised parts have been mounted on the
Fan (e.g. unauthorised wheel).
- the wheel runs in the wrong direction. It will still
work, but the capacity will be reduced to a third
of the normal capacity.
- no motor protection switch is used.
4.0 Maintenance
Periodic maintenance
•In principle, the motor is maintenance-free
because of the factory-mounted, completely
closed special ball bearings, which do not
require any maintenance. Exchange of worn
bearings should only be handled by an
electrician.
•The wheel and the fan housing should be
cleaned every year or according to
requirement. The wheel and the housing may
be cleaned by means of a washing-up brush
and dishwater. Remember to disconnect the
power before the washing and to wipe the
parts afterwards with a dry cloth. This
operation results in a longer life of the Fan.
4.1 Trouble-shooting
Remember always to use a motor protection
switch!
Always use adjustment damper!
In case of problems with the Fan, the following
items may be reviewed in order to check whether:
The volume of air or the pressure is below the
stated level:
•Wrong direction of operation of the wheel.
May be due to wrong electrical
installation. Please double-check the
direction of rotation. Change two phases,
if necessary.
•Leaky channel system.
•Poor inlet/outlet possibilities near the Fan
may reduce the yield (e.g. 90° bend
before the inlet).
•Damaged wheel.
•The rotation speed has been set lower.

•If the temperature deviates substantially
from the lab measurements, where the
temperature was 20°C with an
atmospheric pressure of 101.4 kPa.
•The dampers have not been correctly
adjusted.
•The central lid on the sound box is turned
the wrong way and thus blocks the air.
•The suction net has been blocked by
cotton waste, a cloth or the like.
Vibrations and noise
•The base is not even/stable.
•Elements coming from the outside are
stuck in the Fan.
•Damaged wheel or motor.
•The wheel is loose.
•The wheel may have become unstable,
for instance as a result of dirt on the
impellers.
•The wheel is rotating in the wrong
direction.
•The Fan supplies more air than for which
the equipment has been dimensioned.
Use adjustment damper.
•Loose bolts or screws.
The motor is overtaxed
•The cabling of the motor is not correct.
•The shaft has been bent.
•The Fan has over-capacity in relation to
the resistance in the system. Use
adjustment damper.
•The speed of the motor is too high.
•Defective motor –please contact your
dealer!
