Design Characteristics

Corning DuraTrap AT and AC filters are designed for the highest level of performance.


  • Controlled porosity and mean pore size, in addition to thinwall product options, enable high filtration efficiency
  • Low expansion and low thermal conductivity provide excellent regeneration performance as well as long-term durability
  • Pressure drop performance is enhanced by tailored filter geometry and microstructure attributes
  • Large frontal area (LFA) options can improve performance by lowering back pressure and increasing geometric surface area
  • Corning’s innovative asymmetric cell technology (ACT) provides ash storage benefits and can help manage lifetime pressure drop requirements
