KL Information
Keller Lufttechnik is a worldwide technology company specializing in the
capture and separation of a variety of air pollutants, as well as the reduction of
emissions in industrial applications. The family-owned company was founded in
1903 and is now managed by the fourth generation, combining both tradition
and innovation.
All industrial manufacturing processes generate air pollutants. These

substances are released during mechanical machining, thermal processes,
during treatment technology, in the use of cleansing agents and solvents, or
throughout various painting and refinishing stages.
Foreign substances in the air have an adverse effect on the manufacturing
process and on the finished product itself. They must, therefore, be captured,
separated and exhausted effectively and reliably. Keller Lufttechnik develops,
plans and manufactures exhaust systems that offer an appropriate solution for
air quality control.
To achieve this goal we rely on an extensive and proven product range to
solve problems in the fields of dry and wet separation, as well as in oil/coolant
mist separation. By utilizing innovative filtration technologies and efficient
planning, we achieve optimum separation results. This way, Keller Lufttechnik
provides custom tailored systems of the highest quality that include solutions to
individual problems.
In addition,, Keller Lufttechnik offers complete service packages covering the
entire service life of all aspects of our exhaust systems: from the initial planning
phase, to the approval and permit processes, to installation and commissioning,
and finally to after-sales and service.
