Air Filtration for Electronic Devices
Main filter and central filter
Filtration solutions for electrical appliances in the private and commercial sector.
We develop Main filters and central filters for a wide range of vacuum cleaner types and applications, from private homes to building cleaning and construction sites. The combination of different media and designs (round or flat pleated filters as well as special designs) enables an individual design for optimum use.
Flat pleated filter, round filter or plate air filter
Depending on the requirements in the commercial sector, we also equip the filters, for example to be water and oil-resistant or fire-retardant for ash extractors. You can also choose from filters for manual and automatic cleaning as well as washable versions. The efficiency of the filter is precisely matched to the respective application, from IFA L to the high HEPA level.
In addition to vacuum cleaner bags or other dust containers, domestic vacuum cleaners also contain filters that need to be cleaned or replaced regularly. This is because although dirt and dust end up in the Header Tanks or bag, filtration, especially of microparticles, cannot take place at this point. With bagless vacuum cleaners, a central filter is required in addition to the frequently installed cyclone separator in order to protect the turbine or drive from contamination and damage.

A comparison of depth filtration and surface filtration: In suction operation, a distinction is made between depth and surface filtration. Surface filtration means that the pollutants are trapped inside the medium, where they cannot be removed by a pressure pulse, or only to a very limited extent. With cleanable filters, surface filter media are used in which the filtered dust is deposited on the surface in the form of a filter cake and can be easily removed there, e.g. by a pressure pulse.
