Dry Filtration

PTFE felt is the 'ultimate' in high temperature filter media technology. Of all the fiber types used in the Fabric Filtration industry, PTFE offers the best combination of chemical and thermal properties, including a maximum continuous operating temperature up to 250° C.

PTFE from Lydall Industrial Filtration Limited combines the latest in PTFE felt manufacturing process development with superior global PTFE fiber sources. Resulting from substantial investment in proprietary carding and needling techniques, PTFE felts possess the optimum in uniform fiber distribution, pore structure, and felt consolidation. All of this is then supported with our best-in-class heat stabilization process. Our waste incineration range is the premier PTFE felt technology available in the Air Pollution Control market today.

The Advantages

  • Can be used continuously at 250° C with short term spike exposure to 260° C
  • Can be used in wide range of chemical environments from pH 2 to pH 13
  • ePTFE membrane laminatable grades available
  • Cost effective

Although it is uncommon to apply chemical treatments to the filtration surface, PTFE felts are available in ePTFE membrane laminatable grades to assist with emissions and/or pressure drop challenges.

Our waste incineration range is now used successfully in the most chemically and thermally demanding applications such as incineration, combustion, TiO2, carbon black, chemical, and pharmaceutical manufacturing.
