Description
This device is intended for dry use. It is suitable for collecting flammable and health-endangering dust. The device is completely electrically conductive (antistatic), with electrostatic discharge taking place via electrically conductive wheels to the conductive floor covering.
The type and properties of the suction medium (material), as well as the possible risks with regard to increased electrostatics caused by the transport of the material, must be known to the operator. When vacuuming problematic materials, the device must also be integrated into the operational potential equalization using the associated earthing clamp before use.
The most effective pneumatic filter cleaning system is the MFA alternating filter cleaning system.
This development from Krahnen cleans the filter element 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, squashed or subjected to other mechanical stresses.
