Years of experience with star-pleated filter cartridges are the basis of filter design at MAHLE for many applications. Areas of application comprise aspiration for pneumatic transport, silo ventilation, mixer and mill top filters, central and workstation extraction systems, and the extraction for bagging and packaging systems. High-quality filter media, combined with a cleaning system tuned to the filter cartridges, are the foundation.

Reliable dust removal requires tuning of all components. Since dust properties can vary a great deal and depend on parameters such as dust fineness, bulk density, adhesion and agglomeration properties, or moisture, they are difficult to estimate in theory. That's why technical experiments and practical experience are of decisive significance at MAHLE, in order to reliably test dust filter concepts and their operational reliability.

MAHLE dust collectors are distinguished by their compact design, minimal energy consumption, long filter cartridge service life, and low noise level. The dust collector must not take up too much space, especially for interior installations. With the use of star-pleated filter cartridges, a very large filter surface can be placed in the tightest of spaces. In order to improve flow ratios and thus performance, MAHLE has developed, among others, conical filter cartridges.
