Safety,
it’s a matter of Tact.
Kärcher expands its range of safety vacuum
cleaners and presents two new machines in
the M and H class categories1.
Developed for use in the construction trade
and industrial environments where there
are large volumes of fine dust, this new
generation of robust, wet and dry vacuum
cleaners quickly make achieving maximum
cleaning performance easy and safe.
Featuring the new sensor-controlled,
automatic filter cleaning system (Tact),
the vacuum cleaners detect when the flat
pleated filter needs to be cleaned and
quickly reverses the air flow, to blow air
through the filter, enabling continuous
operation for the user without any loss of
suction power. They also optimally select
the filter cleaning interval, depending on
the quantity of dust being vacuumed: this
enables large quantities of dust to be
collected without the need for manual filter
cleaning.
Suitable for collecting large volumes of safe
as well as hazardous substances, such as
asbestos dust, the PTFE-H flat pleated filter
(HEPA 13) used in the H class models, is the
first cleanable filter in a wet and dry vacuum
cleaner for this dust class: with a filtration
level of 99.995%.
As well as the outstanding features of
our existing NT vacuum cleaners, these
new models also include: electronic filter
detection and air flow monitoring, so the
vacuum cleaner only starts when the filter
is correctly installed, which ensures optimal
safety for the user. If the air flow falls below
a certain value, a warning signal sounds that
indicates a blockage or full container. Thanks
to its grounding conductor and conductive
accessories users are effectively protected
against an electrostatic charge, which can
occur when vacuuming dry dusts.
Sturdy housing with a bumper at the front and
large metal castors provide ultimate stability,
transportability and a long service life –
1 Dust class L: Low-risk hazardous dusts such as lime or plaster dusts. Max. transmittance: ≤ 1.0%.
Dust class M: Medium-risk hazardous dusts such as wood (beech, oak) or paint dusts. Max. transmittance: < 0.1%.
Dust class H: High-risk hazardous dusts such as carcinogenic dusts or mould. Max. transmittance: < 0.005%

making it easier to move the equipment from
site to site. The flat, non-slip top provides a
secure hold for the user’s toolbox, and slots
on the machine allow accessories to be
stored securely.
Additionally, new bayonet locks and large
clips on the floor nozzle allow the quick
change of accessories between wet and dry
applications, without the need for any tools.
The suction hose now connects directly into
the container head allowing maximum use
of the container space, and a significant
reduction in noise when vacuuming small
quantities of dust, making these machines a
powerful ally.
The new range includes:
