Premium Filterbag FP 40:
3 in 1
With the development of the new
Kobold VK 140
comes also a brand
new and innovative filtering
technology included in the
Premium Filterbag FP 40
.
The new
Premium Filterbag FP 40
has 3 features in 1 filterbag:
high filtration efficiency (HEPA
classification);
optimized dust capacity (rela-
tive to the comparatively small fil-
ter volume);
odour filtration and a pleasant
fragrance in combination with
Dovina.
Moreover, with the use of the new
Premium Filterbag FP 40
, the great
suction power of the
Kobold
VK 140
lasts for a longer period.
In contrast to the
Kobold VK 140
other vacuum cleaners need at
least 2 filter elements for achieving
a comparable filtration
performance.
The so called HEPA filter (High
Efficiency Particulate Air Filter) is
integrated inside the Filterbag, this
allows the filtering of the smallest
particles, inhalable by man, which
can cause allergies.
The new filtering system

Filtration Efficiency
(HEPA, High Efficiency
Particulate Air Filter)
The filtration efficiency of filter
elements is evaluated by the
European standard EN1822.
According to this standard the
Premium Filterbag FP 40
has
achieved HEPA H11 level, this
means that our Filterbag can block
up to 99% of particles with size
around 0.09
µ
m (1000 times
smaller than a human hair), and
since bacteria have an average size
of 0.5
µ
m to 50
µ
m, the
Premium
Filterbag FP 40
effectively filters
out 99% of all bacteria.
To achieve this result, we used
special materials that attract dust
and dirt thanks to their particular
electrostatic charge.
The
Kobold VK 140
system has
achieved the TÜV seal as a
guarantee for allergy sufferers: the
emission of allergens are below all
known medical and allergological
limits.
Optimized Dust Capacity
The
Kobold VK 140
was designed
to be compact and lightweight and
extremely easy to handle, and even
the
Filtrello Premium FP 40
was
designed to have great dust
capacity despite its relatively low
volume of just 2.5 liters.
This is thanks to the special bag
configuration, with three different
layers, shown in
FIGURE B
.
Every layer has to fulfill a special
filtration function.
The pre-separation layer consists
of a very voluminous fabric
material which removes larger
particles and fibers (e.g. from
animals, carpets, dust etc.) and
stores these inside the layer.
However, smaller particles can
penetrate the pre-separation layer,
but the adjacent precipitation layer
removes these very small particles.
This is thanks to their special
electrostatic charge.
By the pre-separation of larger
particles and fibers a premature
clogging of the filter bag can be
avoided and the dust capacity of
the filter bag can be increased.
This ensures a long-lasting and
high suction power for the
Kobold VK 140
.
The outer layer is made of a
strong fabric designed to prevent
damage to the inner layers.
