AIR / GAS FILTERS + SEPARATORS
We design filters, filter separators an d multicyclones in all variaties.
Being a specialist on the filed of filtration and separation of solid and
liquid impurities out of gas streams. Filtan built separators (AD-Merkblatt
design code) for a working pressure up to 500 barg. Due to their special filter
elements the filters are capable of separating the finest impurities with
a very high separation efficiency.
The separation efficiency is the most critical and important parameter of
Many years of testing and extensive computer calcuations enables us to know
exactly the separation efficiency of various filter materials. A very high
conformity has been found between the actual tests and the computation. These
results can be reproduced to support the efficiency of the FILTAN filter separators.
The application of this filter is the removal of solid impurities
out of air and gas streams. A pressure vessel holds various filter elements,
depending of the volume of the gas flow, for example made from star folded
impregnated cellulose or of neddle felt material. The gas flows from the outside
to the inside of the cartridges, thus separating the solid particles. This
is known as "surface filtration". The fine solid particles are separated
on the impragnated star folded filter element surface. Through continous separation
the surface becomes more and more clogged by the dust particles. Consequently,
the differential pressure increases until the elements are bursting. Therefore
the elements have to be changed at a certain level of the differential pressure.

Air / Gasfilter-Separator
The application of this filter separator is the removal of solid impurities
and precipitation of condensate, also in mist form, out of air and gas streams.
The pressure vessel is equipped with coalescer elements. The elements consits
of various layers of packed glass fibre. Fine and finest droplets are carried
by the gas stream into this layers. These droplets encounter fibres, stick
down to them and run down. On the way downwards they meet other droplets
and agglomerate to larger droplets which are flowing down inside the fibre
glass layers also. To achieve the high separation efficiency the gas muts
flow from the inside to the outside of the coalescer elements. If no solid
particles are present in the gas stream the replacement of the elments is
The application of the two types of separators is the removal
of solid impuriies and precipitaion of condensate, also in mist form, out
of air and gas streams. This types of separators are equipped with both types
of cartridges such as filter and coalescer elements.

The application of the mulitcyclones is the removal of mechanical and liquid
impurities out of air and gas streams. The use of the multidyclones is recommended
it a separation efficiency off 99% above 8 microns is required, slugs could
occur or maintenance-free operation without the exchange of filter elements
