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
