KemTex® e-PTFE membrane filter
Due
to the KemTex® ePTFA membrane filter the KEMPER extraction and filtration systems act as a reference for all extraction units.
KEMPER extraction and filtration systems are yet efficient where other filtration units are no longer able to filter:
The smallest particles, especially the range of particle sizes smaller than 0,4 µm. They are alveole exchangeable and can enter your bloodstream. Hexavalent Chromium (CrIV) for example is one of these tiny sized particles.
Pulmonary alveoli are the smallest units in the human lung where oxygen is exhcanged between the inhaled air and the human blood. Particles reaching the pulmonary aleoli can also diffuse into the bloodstream, form deposits all over the body and, depending on the chemical structure of the particles, lead up to cancer.
It is absolutely essential for extraction and filtration systems to filter even those finest particles since it is the only possibilty to protect your employees and yourself against serious diseases.
The BGIA (German government safety organisation) tests on the particle size distribution of welding smoke has shown the following results:
| Particles in µm |

< 0,4 |
< 0,6 |

The KemTex® ePTFA membrane filters can filter particles smaller than 0,4 µm, which represent 98.9 % of the total dust particles, according to the BGIA tests.
The effective pore size of the KemTex® ePTFE membrane filter is so small, that even particles with 0,1 µm already will be filtered up to 92 %.The equal zero-emission of the KemTex® ePTFA membrane surpasses all the current regulations even for superfine particles. Especially in the field of particulate matter the KemTex® ePTFA membrane filters prevent a penetration of the particles.
KemTex® ePTFA membrane filters are therefore the ultimate technology concerning all applications. They are yet efficient where conventional filters of the filter class "M" reach their limitations. About 90 % less particles reach the air in comparison with conventional filters.
Rely on the experience of KEMPER and keep your air clean with KemTex® ePTFA membrane filters!

Please pay special attention to the blue symbol for alveole exchangeable dusts.
You can be assured that all filters showing this symbol seperate even the finest dust particles
and are therefore suitable for Hexavalent Chromium (CrIV) exhaust. |
