Industrial Applications

PTFE filter bags are the preferred choice for industries requiring reliable filtration in extreme temperature and corrosive gas conditions.

Waste Incineration

Municipal and hazardous waste incineration plants require filter media that withstands high temperatures, acid gases (HCl, HF, SO2), and heavy metal vapors.

  • Dioxin and furan adsorption compatible
  • Resistant to HCl, HF, SO2, SO3
  • Meets EU WID / EPA MACT emission limits
  • Service life 3–5 years typical

Power Generation

Coal-fired, biomass, and waste-to-energy power plants demand high-temperature filtration with low pressure drop for energy efficiency.

  • Flue gas desulfurization (FGD) compatible
  • Low pressure drop = energy savings
  • Handles fly ash with high SiO2 content
  • Extended bag life reduces maintenance costs

Petrochemical & Chemical

Chemical processing environments expose filter media to extreme acid/alkali conditions. PTFE is virtually inert to all chemicals.

  • Carbon black production filtration
  • TiO2 production dust collection
  • Pharmaceutical intermediate processing
  • Resistant to virtually all chemicals

Frequently Asked Questions

Common questions about PTFE filter bags and Teflon filter bags for industrial dust collection.

What is the difference between PTFE filter bags and Teflon filter bags?

PTFE filter bags and Teflon filter bags are the same product. PTFE (Polytetrafluoroethylene) is the chemical name, while Teflon is the brand name originally trademarked by DuPont. Both refer to filter bags made from fluoropolymer fiber with exceptional chemical resistance and high-temperature performance up to 260°C continuous operating temperature.

What is the maximum operating temperature for PTFE filter bags?

PTFE filter bags can operate continuously at temperatures up to 260°C (500°F) and withstand temperature surges up to 280°C. This makes them suitable for waste incineration, power generation, and chemical processing applications where other filter media such as NOMEX FILTER BAGS would degrade.

How long do PTFE filter bags last?

Under normal operating conditions, PTFE filter bags typically last 3–5 years, significantly longer than PPS (2–3 years) or fiberglass bags (2–3 years). The exceptional chemical resistance of PTFE means the bags do not degrade from acid or alkali exposure, which is the primary failure mode for other filter media in harsh environments.

What emission levels can PTFE membrane filter bags achieve?

PTFE membrane (ePTFE laminated) filter bags can achieve particulate emissions below 5 mg/Nm³, meeting the strictest environmental regulations worldwide including EU Industrial Emissions Directive and US EPA MACT standards. The ePTFE membrane provides surface filtration that captures even sub-micron particles.

Can you supply custom-size PTFE filter bags?

Yes, ECOGRACE manufactures PTFE filter bags in any custom dimension to fit your existing baghouse system. Common sizes range from 120mm to 300mm diameter and 2m to 10m length. We can also provide custom snap-band tops, cuff bottoms, or other attachment methods to match your cage specifications.

What is the minimum order quantity for PTFE filter bags?

Our minimum order quantity varies by specification. For standard sizes, MOQ starts at 50 pieces. For custom sizes requiring special tooling, MOQ may be higher. We also provide sample bags (1–5 pieces) for testing and qualification purposes before placing bulk orders. Contact us for specific MOQ details.
