Dusts and Mediums
For the extraction performance of coarse dirt and heavy materials, a high negative pressure is decisive .
Depending on the fineness or hazard of the dust, filters of dust class M or H are required.
Vacuum cleaners tested according to TRGS 519 are suitable for the extraction of asbestos dusts hazardous to cancer.
Large air volume is recommended for light fumes and vapours, as well as storage filters.
EX-protected industrial vacuum cleaners for extraction of explosive substances and dusts.
Abrasive dusts have special requirements for filters.
Compression vacuum cleaners compress the extracted material and thus increase the extraction volume.
A pump vacuum can be helpful for the extraction of large quantities of water.
Ideal are devices with oil-resistant accessories, such as hoses, filters and seals.
Robust accessories and separation of chips and liquids are important.
