Chronicle
The development of our company at a glance

Kalthoff Luftfilter und Filtermedien GmbH is your partner for filter technology. Our owner-managed, medium-sized company was founded in 1963 by Engelbert Kalthoff and has established itself worldwide. Today we are one of the leading specialists in high-quality airfilter products and services.

We have been preparing ourselves for this market position for many years. With competence and commitment, with unique product developments and a flexible team, which make everything possible for our customers.

State-of-the-art technology for optimum filter performance
A qualitatively high-value air filter is a science in itself. Because it is far more than just a piece of nonwoven in a frame. Into such a high-tech product, a large amount of engineering and development time are integrated. In order to bring the filter media into the required filter shape, the most varied processes are used. Some of these are pleating, sewing, welding and bonding, as well as sealing with compounds. With the product-specific, filter final-assembly, the frame and filter medium are joined. With modern jointing automatic systems and in handicraft work, a dust-proof combination is formed.

INTERMELT pleating machinery

The made in Germany quality and the security of the filters are very much valued by us. For this, the specialists ensure the performance of the respective filter in our filter laboratory with state-of-the-art measurement technologies. These are, for example, the behaviour of separation, pressure drop, as well as the dust-deposition behaviour of the filter type.

This tireless commitment and high level of effort has paid off over the years. Because we are pleased to relate that a lot of our exceptional products are based on our own development work. There is scarcely any better proof of quality – except of course for our many satisfied regular customers. And also in the future, we want to go on developing intelligent and effective products which are leaders in their sector.

Furthermore, Kalthoff Luftfilter und Filtermedien GmbH supports qualifications, such as the FDA certifications which refer to the raw materials of the product. And by means of Hygiene Declarations of Conformity in accordance with VDI 6022, fire-resistance investigations, as well as individual manufacturer’s certificates and compliance certificates, we provide a perceptible level of added-value for our customers.
