The application
The A 3 / 300 S filter mat is a popular option for high quality final filtration in ventilation equipment and systems, and as a prefilter in multi-stage air intake systems. The media and its characteristic features
• The mat is made of high performance nonwoven produced inhouse from polyester fibers with thermal bonding. These fibers are elastic and
break-resistant, so that no fiber fragments are passed into the clean air, and the original nonwoven structure is retained over the entire operational
life.
Fire behaviour: Viledon® filter media satisfy the stringent requirements of Fire Class F 1 according to DIN 53438 and are thus self-extinguishing.
• Certified quality: The A 3 / 300 S filter mat has been tested according to EN 779 and ISO 16890 and is manufactured under our certified quality
management system to ISO 9001.
This offers all users the reassuring certainty that all filters will be supplied in consistently high standardized quality, documented by marking
the filter mat with brand name, type designation, and filter class.
