Description
The most effective pneumatic filter cleaning system is the MFA alternating filter cleaning system.
This development from Krahnen cleans the filter elements without additional auxiliary energy, but uses the suction volume of the vacuum cleaner and the differential pressure to effectively clean the filter. At least two filter elements per vacuum cleaner are required for this. If the filter surface load increases and the vacuum cleaner no longer achieves the desired suction power at the suction point, the user can quickly blow the filters clean again with the MFA filter cleaning system. In contrast to other manufacturers, where the filter is cleaned using pressure surges, filter shakers or vibrations, the important filter fabric of the Krahnen vacuum cleaners is not compressed, crushed or subjected to other mechanical stresses.
