1.0 General safety precautions
IMPORTANT – Please study all the instructions before
mounting and use.
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 use of the equipment.
All electrical installations must be carried out by an
authorised electrician.
1.1 Dangers
Danger of mutilation when dismounting the hose/nozzle
from the exhaust. Be careful.
Hoses mounted with spring balance F/LR: Guide it
slowly. If released it will accelerate out of control.
To minimize the risk of danger all instructions in this
manual must be followed carefully.
1.2 Field of application
GEOVENT Pneumatic rail system is developed for the
extraction of exhaust. When installed
correctly the Pneumatic rail system allows a vehicle to
be placed in position in a safe manner.
The hose is extended and fastened to the exhaust of the
vehicle.The Pneumatic rail system must not be used for
extraction of aluminum dust, flour, textile and wood dust
or other explosive media without written prior consent
from Geovent.
When in doubt, contact Geovent A/S.
1.3 Technical Specifications
Temperature extracted air: Max. 170°C
Temperature, surroundings: Min. 0 - 50°C
If the extracted air is hotter than 170°C the standard
hose will melt. To prevent this, several precautions can
be taken. See trouble shooting in section 4.1.
Noise
The Pneumatic rail system in itself does not produce any
noise. The noise level relies on a number of factors,
primarily the diameter of the hose and the extracted air
flow. If the hose is too narrow, noise will occur.
Optimal air flow
A number of factors must be taken into consideration
when selecting the hose for the Pneumatic rail system.
An important factor is the air flow:
Hose ø100 mm 400 m3/h
Hose ø125 mm 600 m3/h
Hose ø150 mm 1.000 m3/h
1.4 Construction
Pneumatic rail system example
A: Fan MSFG-200-3 1,1kW – can deliver up to 2.100
m³/h.
B: Trolly with mounted spring balance.
C: Connection for rail system. Rails come in lengths of 2
meter and can be combined to suit your needs.
D: Suspension bracket for ceiling mounting.
E: Decoupling switch.
F: End stop.

4
Mount the spring loaded stop and the end plate.
The exhaust pipe
The side mounted exhaust pipe should be positioned ac-
cordingtothedrawingandpointatrightanglesoruptomax.
45° backwards. The pipe should be straight and lie flush
with or be slightly angled out from the side of the vehicle.
Be aware that it may be necessary to make
modifications to the exhaust system of the vehicle to
ensure the best possible position of the exhaust pipe.
Mount the exhaust clamp on the exhaust pipe.
Mount it approximately 50 mm from the exhaust pipe
outlet.
The specific position of the exhaust clamp may have to
be adjusted when the system is tested.
2.0 Installation
The Pneumatic rail system is delivered in separate parts.
Recommended height of installation is 3 to 5 meters.
Use one suspension bracket approximately every 2 me-
ters of alu profile: One in each end and one at each joint.
Installation should be carried out by a trained profes-
sional.
Before installing, consider the optimal placement for the
Pneumatic rail system. Is there sufficient room and is it
possible to perform duct work and service the system.
The Pneumatic rail system can be installed on both a
plane and slanted ceiling.
Depending on the individual solution some components
may not be included.
The nozzle has to be pulled downwards at connection.
Then the balancer will be activated.
Installation on either the right or the left side of the vehicle.
Procedure:
Place all the profiles on the floor and screw the profiles
together with the extension bracket.

Safety coupling
The safety coupling is placed in the lower part of the
hose – between the pneumatic switch and the nozzle.
The safety coupling disconnects if the nozzle does not
disconnect from the exhaust pipe when the fire truck le-
aves the station.
The force to make the safety coupling disconnect is from
the factory set to a minimal level.
You must adjust the 4 screws on the side of the safety
coupling (see picture below) in order to a. Make the
connection stay connected in normal use b. Make the
coupling disconnect if the nozzle does not disconnect
from the exhaust pipe when the fire truck leaves the sta-
tion.
After a disconnection the safety coupling must be re-
attached by pushing the 2 parts of the safety coupling
together.
Check that it is properly reattached by pulling the hose.

2.2 Test run
After installation, make sure that the trolly can move
freely along the entire rail. Test that the nozzle stays
attached to the vehicle while in motion and that it
disconnects in time.
If the nozzle is not tight or it does not stay fixed on the
exhaust pipe – or if the nozzle does not disconnect in
time, the position of the exhaust clamp may have to be
adjusted.
Exhaust clamp, approximately 50-55mm from the tip.
3.0 Daily usage – user instruction
• Open the station door and start the exhaust extraction
fan (as an alternative, the fan can be connected to an
automatic start/stopsystem).
• Reverse the vehicle so that the exhaust pipe is just
outside the station door.
•
Locate the nozzle of the flexible hose on the exhaust
pipe. Fasten the nozzle by activating the pneumatic
switch on the hose.
•Reverse the vehicle into its parking space. The hose
should always be connected to the exhaust pipe while
the vehicle is parked in the station.
Disconnection
• Make sure the extraction hose is connected to the
exhaust pipe and that it is firmly fastened.
• Start the fan and open the station door. Drive the ve-
hicle straight out from the garage with a maximum
speed of 20 km/h (12 mph). The hose automatically
disconnects when the vehicle is driven out.
The Pneumatic rail system will not work as
intended if:
• Unauthorized parts are used on the rail system.
• The system is used for other purposes than described
in this manual.
• The fan is turned off.
(This will result in the hose melting.)
The flexible hose can withstand 170 °C for con-
tinuous running. Use at higher temperatures will
shorten the life of the product.
Therefore, avoid tasks that require extended
periods of continous running which will genera-
te high exhaust temperatures.
4.0 Maintenance
Periodic maintenance
• Maintain trolleys on suitable intervals for optimum
performance.
• Avoid running over the hose to reduce wear and tear.
• Make sure that the hose is not bent right after the
exhaust pipe.
• Measure the air flow on the Pneumatic rail system at
least once a year. If the air flow is too small the hose
can melt.
The entire Pneumatic rail system should be checked at
least once a year by a trained professional.
4.1 Trouble shooting
In case of a problem with the Pneumatic rail system
check the following issues:
Typical problems when installing the
Pneumatic rail system:
Noise problems
• The Pneumatic rail system is not properly fastened to
the ceiling or the ceiling is not stable enough.
• More air is run through the system than intended. Use
balancing damper.

8
Hose problems
• The hose melts near the nozzle. This will happen if the
air flow is not sufficient or if the hose is bent too much
and too close to the nozzle. In this case straighten the
hose and/or increase air flow.
Alternatively use a high temperature hose near the no-
zzle.
