Air Filtration for Electronic Devices

Main filter and central filter

Filtration solutions for residential and commercial electrical appliances

We develop specific solutions for a broad 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 custom versions) allows an individual design for the optimum application.

Flat pleated filter, round filter or plate air filter

Depending on the requirements in the commercial sector, we additionally equip the filters, for example, water- and oil-resistant or fire-retardant for ash vacuum cleaners. Furthermore, you have the choice of filters for manual and automatic cleanability 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 the private sector, vacuum cleaners contain not only dust bags or other dust containers, but also filters that need to be cleaned or replaced regularly. This is because dirt and dust do end up in the container or bag, but the separation of microparticles in particular cannot take place at this point. In bagless vacuum cleaners, a central filter is necessary in addition to the frequently installed cyclone separator to protect the turbine or drive from contamination and damage.

Advantages

Video

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