ProTex is your solution and our initiative on the way to energy-efficient dust removal
Increase energy efficiency using ProTex filter media
Filtering emissions is the task Intensiv-Filter has been addressing it-
self to since its founding in 1922. We are a leading specialist in filter-
ing installations in the international markets. This applies both to new
installations as well as conversions for a wide range of applications.
Besides the filtration features required, saving energy is the priority in
the development of ProTex filter media. The pressure drop of the filter-
ing installation and therefore the demand of energy are reduced when
using ProTex filter media. New installations as well as existing instal-
lations, in which a change of filter bags is necessary, can be equipped
with filter bags of the new ProTex quality.

Pressure drop reduction
Using ProTex, the filter pressure drop
can be reduced by more than half
compared to conventional filter media.
Based on the entire filtering installation,
the guaranteed values for energy con-
sumption and operating costs can be
reduced by up to 40 percent.
The use of high quality microfibres and
a special needle punching technique
guarantee an optimal surface filtration
and low residual pressure drop. In ad-
dition, the pressure increase within one
filtration cycle will be reduced signifi-
cantly.
Alternatively, the filter system capacity
can be increased with ProTex – while
investment and operating costs remain
the same.
The savings potential
Sample calculation for an installation of the
stone/earth industry with fine-particle, mineral
dust, based on a filter surface of 1,000 m² and an
operating period of 8,000 h/a:
The test results point out the significant increase of the energy efficiency. This has been validated by extensive trials under
repeatable test conditions in our filter test center.
