KE Fibertec has developed a fabric duct air distribution solution that meets the requirements in the MIL-PRF-32107 specification.

The concept as specified in MIL-PRF-32107 was created in 2000 following an inquiry from NAVSEA in Philadelphia. They needed a system that was flexible, lightweight and fire resistant and thus a good alternative to heavy sheet metal/grills and diffusors on the ships. 

The use of fabric ducts offer many advantages.

For the shipowner they are:

  • Low weight compared to sheet metal systems. Resource comparisons show 70% to 80% savings on weight
  • A lighter and faster ship meaning lower fuel consumption
  • Energy savings through lower system operating pressure

For the engineer they are:

  • Tried and tested concept
  • Flexible layout with lego system (zippered sections)
  • Full MIL-SPEC available by NAVSEA
  • Catalogue with layout advise available
  • Easy to install

For the sailor they are:

  • Flame retardent material (Nomex)
  • Draft-free air distribution
  • Condensation free system
  • Launderable (keeping the system, and thereby the air supply, clean)
  • Noise-reducing (soft material)
