Filter bags made of Aramide needle felt combined with properly prepared acrylic fibers by a special needling method result in a felt that is more durable than pure Aramide.

The main features of this design are:

  • high resistance against hydrolysis
  • high resistance against oxidizing
  • usability in acidic working environment
  • good filtration efficiency
  • lesser pressure drop
  • slower fiber degradation


This material is ideal for filtration processes where the lifetime of the bags is of great importance. It is mechanically more durable than ordinary “Nomex” and  is  available in different weights, with PTFE fiber support, and in water and oil repellent PTFE-based finish.

Applicable in the following industrial sectors:

  • gypsum industry
  • ceramics industry
  • foundry and metal industry
  • cement industry
  • production of asphalt
  • drying units
  • biomass combustion plants
  • production of construction chemicals
  • clinker production
