• for dry pollutants in large quantities

• Surface-type filtering by means of cleanable filter elements.
• Pollutants are separated on the surface of the filter cartridge.
• Cleaning is done automatically by means of compressed-air reverse purging.
• The precipitated dust accumulates in a dust collecting bin.
• The cleaned air gets back into the working room.
• The filter cartridges have a long life.

Modular systems facilitate combinations of cartridge and storage filters

• for complex types of pollutants
• if operating conditions change

• The extracting unit is sub-divided into several functional levels.
• For each level, a choice of combinable modules is available.
• The vacuum generator always forms the basic level.
• It is the basis of freely selectable cleanable cartridge filters for big quantities of pollutants and/or for "Hepa filters" withholding smallest pollutant particles.
• Completed by various pre-filter and afterfilter means, persistent pollutant combinations can thus be collected and filtered out.
• For any application, a totally specific solution can be configured, for example, for various materials and pollutants.
