Viledon Filters Create a Climate of Confidence yiledon‘1 Freudenberg Filtration Technologies

High indoor air quality is not a matter of course ... Recently, indoor climate control systems have become the focus of increasing interest, since among the causes cited for Sick Building Syndrome are poorly maintained and hygienically inadequate HVAC (Heating, Ventilating and Air-Conditioning) systems. To protect the health of the staff concerned, and also for reasons of production-specific or technological conditions, tougher requirements have to be applied for the performance capabilities of air filters in HVAC systems. The air filters used have to ensure that the content of dusts,...

the density increasing towards the clean-air side. The filter media of the WinAir 75 up to WinAir 98 have a 3-layer progressive structure, with a high-arrestance microfiber layer being surrounded by a prefilter layer and a support layer. This provides an optimum of filter performance and dust holding capacity. In the case that old single-stage filter systems are to be operated with Filter Class F7 to EN 779, we advise using the Viledon NanoPleat cassette filters Type MV 85 HSN. Under critical on-site conditions, such as abrasive or sticky dusts, high volume flows, and if process safety does...
