Nowadays, air pollution may cause a number of different diseases. Because indoor air can be 100 times more polluted than outdoor air, it is hardly alarmist to maintain that diseases are more easily spread indoors. Research shows that the new influenza virus many people fear is obviously more easily spread in an unventilated indoor environment. Fresh air is vital for the health of the occupants and the health of the home, so continuous air exchange within the home is vital. At the same time, homeowners also want energy efficiency to keep living costs low.
Based on our long-standing and extensive know-how and more than 60 years' experience in filtration, we develop tailor-made and innovative filtration solutions with our customers. The proper FAFS portfolio can effectively protect against PM2.5, PM1.0, haze and carbon dioxide from outdoor air, and also meet energy efficiency requirements.
Optimal one-shop-stop solutions with different level filters
High-performance filter solutions with innovative filtration media
A specific product range, including an impregnated, pleatable carbon medium from in-house production, has been developed to address the formaldehyde challenge in new homes in China. It meets the stringent performance requirements of Chinese standard GB/T18801. The carbon medium is an ideal combination of gas-phase filtration and particulate filtration in one filter for PM10, PM2.5, formaldehyde, TVOCs, ammonia, odors, etc. A biocide- and nanosilver-free biofunctional layer can be integrated upon request to provide triple protection against household air pollutants and contaminants.
Premium quality of raw materials and production?
We purchase high-quality raw materials and manufacture all our particle, activated-carbon and combifilter media in-house. These media are in turn converted into filter elements using, in some cases, patented technologies. Moreover, we are also able to manufacture support housings for our filter elements. Thanks to this high development and production penetration, we are able to ensure that the very latest state of the art is always incorporated in product optimization.
Up-to-date quality management system
Our quality management system per TS 16949 provides a secure underpinning for all operations, from the initial development step through delivery of the series-manufactured products to after-sales service. In addition, we also responsively adhere to further requirements, such as specific quality standards drawn up by our customers.
Rigorous testing process
It is vital to design components to ensure optimum filter area loading and filter lifetime in the specified purifier installation space even under the toughest of conditions. Against the background of lengthy practical experience and purposeful observation of the filter’s characteristics over its useful lifetime, conclusions can be drawn for component optimization and the development of new filter media. Our filters are designed and developed using state-of-the-art testing technology. In test channels conforming to DIN 71460-1, our filters are tested with exhaustive rigor.
Besides the standard tests in accordance with DIN, each filter is also subjected to Freudenberg’s own specific tests. These special tests include exposing the filter to atmospheric dust, synthetic fine dust, temperature and moisture stress, and much, much more. To supplement these laboratory tests, the filter’s performance data are also recorded under real conditions in a traveling vehicle. Only when the filter has passed all the tests “summa cum laude” is its development regarded as concluded. And mass production, of course, is also subject to continuous quality control, from the filter medium to the finished filter cassette.
Strong research and development capability
We are solidly backed by the Freudenberg New Technology Unit, which focuses on the research and development of market-leading technology. Globally, we have more than 60 experts in various fields, including filter selection, design and testing.
Many different applications necessitate the use of a fresh-air filtration system:
- Airborne particles from ambient air
- Household Contaminant loads caused by evaporants from furniture, flooring and paint
- NOx,SOx,H?S, Cl?, NH3, odors and other gaseous pollutants from ambient air
The air filters used in stationary filtration system are the key elements for removing the various air pollutants and harmful gases. Freudenberg provides one-stop solutions including HEPA filters, gas phase filters, combifilters and anti-allergy filters, etc.
The filters can meet the requirements of different industrial standards, including EN 779,ISO 16890, EN 1822 and ASHRAE 52.2.
