AFT filter bags / pleated filters features and benefits

ePTFE membrane filter bags - for increased throughput, lowest differential pressure and longer bag life

Fiberglass filter bags - for best performance for applications with temperature constraints of 200oC to 260oC

PPS filter bags - for improved acid resistance over Aramid at higher temperatures, with a temperature limit of 375°F (190°C)

Broken bag detectors - for early detection of opacity problems

Expert knowledge

FLSmidth AFT filter bag specialists have the expertise to help select the best media based on application, process conditions, gas temperature, dew point, dust loading, particle size, abrasiveness, potential for process upset and expected life.

Environmental regulation standards
FLSmidth AFT engineers have extensive field experience in all industries and applications worldwide including cement, minerals, utilities, metals, chemicals and carbon black. FLSmidth AFT works with customers to develop a total strategy to ensure compliance with environmental requirements such as:

  • NESHAP (National Emission Standards for Hazardous Air Pollutants)
  • MATS (Mercury and Air Toxics Standards)
  • MACT (Maximum Achievable Control Technology Compliance)
  • CISWI (Commercial/Industrial Solid Waste Incinerators)
  • IPPC (Integrated Pollution Prevention and Control) – European Union

Unsurpassed filter media

FLSmidth supplies a wide range of filter media, parts and accessories to refurbish and improve your air pollution control equipment. Our parts and accessories are designed to meet or exceed the OEM specification to increase dependability and reduce costly downtime.

AFT™ filter bag media 

AFT™ filter bags are made from a wide range of filter media, including:

  • PTFE Membrane
  • Polyester
  • Fiberglass
  • Aramid
  • Huyglas
  • PPS
  • Polypropylene
  • Basalt
  • P-84
  • Cotton
  • Teflon® / PTFE
  • Wool
  • Acrylic
  • Nylon
  • Mixed Felts
  • Blends



To meet demanding environmental and process requirements AFT developed finishes to enhance the performance of traditional filter media. Each finish is designed to achieve performance objectives such as enhanced release, chemical resistance and flex resistance. Our technical support team will recommend the finish best suited for your process.

AFT™ finishes

  • PTFE
  • Tri-Component silicone/graphite/PTFE
  • Acid Resistant 
  • Singed
  • Glazed
  • Silicone
  • Oleophobic
  • Hydrophobic
  • Many more

PTFE membrane

ePTFE membrane

A wide range of woven and felt filter media with ePTFE membrane is available. The membrane lamination serves as a primary filter surface allowing air to pass through while the fine particulate is collected. The membrane allows for excellent dust release and particle retention, keeping the filter bags as clean as possible for longer life.  

Features & benefits

  • Lower differential pressure 
  • Higher throughput
  • Much more efficient in capturing submicron dust particles
  • Less filter bag cleaning to reduce compressed air usage
  • Longer filter bag life

Pleated filters and cartridges

Pleated filters provide 2–3 times additional cloth area over standard bags in dust collectors where increased production demands have overwhelmed original capacity. FLSmidth AFT offers cartridges and pleated filters made of cellulose, synthetic blends, Aramid, PPS and spun bond polyester with special coatings, finishes or PTFE membrane. These can be constructed using galvanized or stainless components, designed to meet a variety of conditions and temperature requirements.

Features and benefits

Properly applied, pleated filters will:

  • Reduce pressure drop
  • Increase collection efficiency 
  • Lower pulse air consumption
  • Provide 2-3 times additional cloth area
