Electrically operated industrial vacuum cleaner on roller carts suitable for continuous operation for the dust Ex zone 21/22 for collecting flammable and health-hazardous dusts.
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 suction cup and the differential pressure for effective filter cleaning. 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 free again with the MFA filter cleaning system. In contrast to other manufacturers, where filter cleaning is carried out using pressure shocks, filter vibrators or vibration, the important filter fabric of Krahnen vacuum cleaners is not compressed, crushed or subjected to other mechanical loads.
