172 x 172 x 10 mm Polyester-Filter mat

Characteristics:

- Filter class G2 according to EN779 and ISO coarse 30% according to ISO 16890
- for filter fan / exhaust filter with a mounting cutout of 177 x 177 mm
- high performance nonwovens from elastic, break-resistant polyester fibers with thermal bonding
- progressive in structure, with layers being arranged behind each other so as to ensure that the density of the fiber layers
  increases towards the clean air side
- this optimized the defined filter performance and the dust holding capacity, resulting in longer useful lifetime for the filter   
  concerned (slow pollution and high durability)
- By high dust holding capacity, the filter mats are particularly economical
- fire behaviour: the filter mats satisfy the stringens requirements of Fire Class F1 according to DIN 53438 and are thus
  self-extinguishing
