NOTE
Do not switch off the product overnight,
simply reduce the power and leave it
running to extract the remaining dust. If the
product is shut off overnight, the fine dust
will be distributed to other areas once the
pressure has equalised.
Use as air purifier
The renovated area cannot always be
completely separated from other areas, for
example if the room is too large or has a
complex shape. In this case the product can
be used as an air purifier. Place the product
as close as possible to the object that
produces the dust.
Recommended use of filters:
– for dust containing brick and plaster etc.:
G3 + G4 or G3 +
– for hazardous dust such as moulds,
asbestos etc.:
G3 + G4 + H14
Use as a fan
If efficient ventilation is required on a building
site, the product is suitable for this task. Other
potential applications include speeding up the
drying process of paint or filler materials,
ventilation of rooms and removal of chemical
vapours from the work area.
NOTE
The product must not be operated without
filters. As a minimum G3 + G4 filters must
be used even in dust-free locations.

Use for deodorising
Unpleasant odours can be removed from
the air with the G4-AK activated carbon filter.
The G4-AK activated carbon filter is otherwise
identical to the standard G4 filter and is
inserted into its slot.
NOTE
When it is switched off, the product
continues to run for a short time.

Information on using the filters
In order to ensure the best possible
performance of the product, ensure that
dust generated during renovation work with
machines is extracted directly into the
product with a safety vacuum cleaner.
The Wolff range includes machines fitted
with a suction adapter to which mobile L, M,
H class safety vacuum cleaners can be
connected.
The average estimated filter change

To maximise the life of fine dust filters we
recommend always using a pre-filter G3.
– The pre-filter G3 traps 80% of the
particles (dust)
– The coarse dust filter G4 traps 90% of the
particles (dust)
– The fine dust filter traps 80% of
particles > 0.4 μm
– The HEPA filter H14 traps 99.95% of
particle size 0.1 – 0.25 μm and is
specified if the presence of quartz, mould
or asbestos dust is suspected to ensure
that the MPPS dust is correctly filtered.
The filters conform to the requirements of
building regulations with reference to the
extracted air volume.
