The application
The PSB series comprises the following filter mats
• PSB / 145 S
• PSB / 275 S
• PSB / 290 S
PSB filter mats are used for intake air filtration in all kinds of ventilation systems, particularly for coarse dust arrestance
and as prefilter stages. The media and their characteristic features
• The mats are made of high performance nonwovens produced inhouse from elastic, break-resistant polyester fibers with thermal bonding.
• PSB / 275 S and PSB / 290 S are progressive in structure, with layers being arranged behind each other so asto ensure that the density of the fiber layers increases towards the clean air side. This optimizes the defined 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 F 1 according to DIN 53438 and are thus self- extinguishing.
• Certified quality: PSB filter mats have been tested according to EN 779 and ISO 16890 and are 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. The special features of the PSB series
• Due to their high dust holding capacity and their resultant long useful lifetimes, PSB filter mats are particularly cost-efficient.
• All types of this series are especially effective in applications requiring stable arrestance in spite of high dust loading and high air flow rates.
• When used in exhaust air filtration, the advantage of the PSB series is that arrestance and dust holding capacity are very well harmonized.
