Filter plates


  • Improved air flow due to down-flow principle
  • Robustly welded filter pleats that do not choke up 
  • Filter cleaning without moving parts possible
  • Clean-air side inlet nozzles for compressed air
  • Horizontal installation in filter system


  • No restriction over time because 100% of the
  • Filter surface is permanently available
  • Drastic reduction in costs resulting from significantly longer filter life 
  • Less wear as no moving parts are required 
  • Savings due to less compressed air consumption and lower energy costs
  • Time savings by ease of changing the filter plates due to horizontal installation

Automatic cleaning

  • Pressure-controlled breath-responsive cleaning by compressed air 
  • A blast of compressed air from the integrated compressed air tank flows directly into the filter media
  • No need for rotating nozzles due to filter design 
  • Significantly less wear since no moving parts are required

Filter cartridges


  • Large pleat distance while having the same filter area per cartridge 
  • Flexible filter pleats support filter cleaning
  • Even and gentle cleaning using rotating nozzle 
  • Vertical installation in filter systems


  • Less choking up of the filter pleats due to larger distance between pleats
  • Very long service life of the filter elements and rotating nozzles 
  • Cost savings through optimal cleaning properties 
  • Less dust deposition due to being vertically installed

Automatic cleaning

  • Pressure-controlled breath-responsive cleaning by compressed air 
  • A blast of compressed air from the integrated compressed air tank sets the rotating nozzle in motion
  • The rotational movement of the rotating nozzle creates an even flow
  • This achieves optimal cleaning performance of the KemTex® ePTFE filter cartridge

Ideal for welding and cutting

Study by the AWS (American Welding Society) on particle distribution:

  • 98.9% of the dust particles generated are smaller than 400 nanometres
  • Ultrafine nanoparticles can penetrate into human cells
  • KemTex ePTFE membrane filters already have high separation in the nanoscale range
