  • Filter bags with non-standard dimensions
  • Filter bags with Tie cord
  • Special ring types and sizes e.g. “X100” 5.5” polypropylene moulded collar
  • ‘Bucket’ style bags with circular base
  • Square/ rectangular bags
  • ‘Box-type’ bags

  • Filter bags made from speciality fabrics, such as our PVC ‘carbon’ filter bag, antistatic felt or mesh

For demanding applications which require modifications to a standard filter bag product, customisation options include :

  • Reinforced seams
  • Special lifting handles
  • Reverse collar construction
  • Filter media with micron ratings other than standard.
