Safety
Read this manual carefully before starting or us-
ing the device. Store the manual near the device
or its site of use!
Observe the following instructions:
• Do not use the device in potentially explosive
rooms.
• Do not use the device in atmospheres contain-
ing oil, sulphur, chlorine or salt.
• Set the device up in an upright and stable po-
sition.
• The device is designed for indoor use. Do not
use the device at a humidity level of more than
90 % or in the rain.
• Ensure that the air inlet and outlet are not ob-
structed.
• Ensure that the suction side is kept free of dirt
and loose objects.
• Do not cover or transport the device during
operation.
• When using cable drums, always unroll the
cable completely.
m
During damage restoration, provide a
sufficient fresh air supply! The room tem-
perature must not exceed 35 °C. Ventilate
several times a day. If necessary, direct
the exhaust air produced by the VX out of
the room. You can also set up the VX in
another room (not outdoors!) and direct
the air current needed for drying to the
inside.
• Make sure to keep the dust exposure as low
as possible in low pressure operation by using
suitable micro filters (fig. 2).
• Make sure that the suction strainer (fig. 4) is
used when the device is operated with excess
pressure.
• Repair and maintenance work on electrical
equipment may only be carried out by an elec-
trically skilled person.
• On construction sites, the compressors must
only be operated with an upstream residual
current device (RCD) 30 mA.
• Do not operate the device in a heavily
dust-loaded environment (e. g. during grinding
work).
Intended use
The turbines are to be used in low and excess
pressure mode for insulation drying of floating
screeds, flat roofs (warm roof constructions) and
hollow floorings. They are intended to transport
non-aggressive and non-explosive gaseous me-
dia. Any other use is regarded as non-intended
use.
Improper use
The devices are not suitable for the inflation of
bouncy castles or similar objects. Media other
than those listed as intended use must not be
transported.
Personnel qualifications
The compressors may only be operated by ex-
pert persons who have been instructed in the
operation of the devices and trained in insulation
drying techniques. The operating manual is to be
consulted for this purpose. Instructed persons
have been informed of and, if necessary, trained
for the tasks they were entrusted with as well as
of potential hazards resulting from inappropriate
behaviour.

Description of the device
The compressors of the VX series are used for
drying insulation layers. In case of excess pres-
sure drying, the roomair is blown into the humid
insulation layer via bore holes, the insulation
layer absorbs the humidity and returns it to the
environment via the expansion joints.
In case of low pressure drying, a drying chain
(fig. 1) consisting of water separator, air filter
and compressor is used to suck the air out of the
insulation layer. The air sucked out of the bore
holes is separated from solid particles and water
drops inside the water separator. Particles and
mould spores are filtered out by the HEPA and
F7 filters.
Should there be any concerns relating to air pol-
lution due to fibres or spores from inside the in-
sulation layer (GefStoffV: Ordinance on Hazardous
Substances), the use of the low pressure proce-
dure is compulsory in order to filter the polluted
air. The silencer allows to effectively decrease the
volume in occupied buildings.
The humid air has to be dried additionally by ade-
quately powerful mobile dehumidifiers.
• To be able to use the high performance of the
VX compressors, it is necessary to operate the
optional quad distributor Pro (fig. 3) with at
least two 38 mm hoses. If no quad distributor
can be used, the hose diameter should be at
least 50 mm, for otherwise there might be per-
formance losses of up to 10 %.
• This VX distributor is equipped with self-regu-
latory step switches.
• The device comes with 4 power stages:
stage 1 with 100 m³/h; stage 2 with 150 m³/h
and stage 3 with 180 m³/h as well as the boost
stage with up to 245 m³/h. In addition, there
is a "whisper mode" with 100 m³/h as well.
For each of these steps, the VX tries to achieve
the target air volume, regardless of the con-
struction.
