Viledon SO Migration lest mm Pieces cut to customer's specification The filter The main field of application for the PA-5 micron filter mat is final intake air filtration in paint-spray processes involving particularly stringent requirements for air purity. As the first synthetic ceiling filter mat in Filter Class F6, it ensures practically 100% arrestance of particles > 5 pm. The PA-5 micron thus meets even the toughest of quality stipulations in surface treatment technology. The medium and its characteristic features The mat is made of high performance nonwoven produced in-house from elastic, non-breaking polyester fibers. This nonv/oven is thermally bonded and specially smoothed on the clean air side, in order to achieve excellent fiber bonding. So as to ensure permanent retention of particles already collected throughout the entire operating lifetime, the fibers are in addition specially processed to give each individual fiber an actively adhesive surface. The filter medium is progressive in structure, with layers of differing fiber diameters being arranged behind each other so as to ensure that the density of the fiber layers increases towards the clean air side. This optimizes the filter performance and the dust holding capacity, resulting in longer useful lifetime for the filter concerned. Fire behaviour: Viledon filter media satisfy the stringent requirements of Fire Class FI according to DIN 53438 and are self-extinguishing. Certified quality: PA-5 micron has been impartially type-tested to EN 779. 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, filter class, and DIN mark of conformity plus model validation number.

Thermal stability Moisture resistance, rel. humidity •Supplied as rolls, useful width/length Supplied as cut pieces The special features of the PA-5 micron With the PA - 5 micron, not only particles measuring > 10 pm, but even those measuring >5 pm are filtered out almost entirely. Thus the PA-5 micron ensures outstanding production dependability for the user in all sophisticated paint-spray processes. Due to the adhesive fiber surface, the PA - 5 micron is able to permanently bond more than 3 kg/m2 of free-flowing Aloxife dust. PA-5 micron surpasses the highest „S0" class in the Viledon migration test acknowledged throughout the market. For further information on this test, please consult our special „Surface Treatment" brochure. The reinforcing scrim on the clean air side enhances the filter mat's stability and minimizes the risk of damage to the clean air side during installation. PA - 5 micron is resistant to solvent vapours and contains no silicone.
