Pleated filters work the same way as multi-layer filters and their structure is also similar. However, there is a significant difference in the need of achieving a higher filter capacity in comparison to the standard filters. The filtering area is increased by pleating and the filtering layer is thus enlarged. The most common materials are DIN 1.4301 and DIN 1.4401.
We make substitutes (aftermarket) of the original OEM filters in the required quality.
