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.
