Advantages of PUREPACT filter plates for paint separation
- maximum filter area
- high air permeability
- low differential pressure
- Reduction of the fan power
- significantly lower energy costs
- favorable purchase of the PUREPACT filter plates
Cost reduction up to 40%!

DÜRR Eco Dry Scrubber - a good system with a weak point
- with a material thickness of only 2mm, the carrier plate/slit plate is not strong enough
- This causes movements on the sealing surfaces between the housing and the filter plates during operation
- without a highly dynamic seal with high restoring force, dust can enter the clean room along the sealing surfaces
The solution: our PERMAFLEXX flat gasket
- the seal is permanently elastic
- only a very small loss of restoring force even after years
- Fast recovery properties to compensate for the impulses of the pulse cleaning and the associated load changes
We measured it:

Test of an EPDM seal
- the seal is compressed
- the back pressure rises to -94N
- Compression is maintained, over time the back pressure of the seal drops from -94N to -21N
- when the compression is released, the seal loses contact with the pressure plate

Test of the PERMAFLEXX seal
- the seal is compressed
- the back pressure rises to -142N
- Compression is maintained, over time the back pressure of the seal drops from -142N to -122N
- when the compression is released, the seal maintains contact with the pressure plate
