Description

M-KC Features and Benefits:
  • Underwriters Laboratories listed, and complies with NFPA Standards 90A and 90B.
  • Core material will not support mold and mildew growth.
  • Highly resistant to rust and corrosion.
  • Fully lined for efficient air delivery.
  • Large diameter, heavy, spring steel wire helix assures dimensional stability, resists mechanical abuse and provides more efficient air delivery.
  • Bi-directional reinforced metallized jacket resists tearing - reduces chance of damage to vapor barrier.
  • Heavy woven and coated fiberglass cloth core assures quiet performance. Core is almost impossible to puncture or tear. No more concern about fiber in the air stream or loss of conditioned air.
  • Uniquely constructed core will not unravel when cut.
  • All components of M-KC are self-extinguishing and will not support flame (see oxygen index figures under application and engineering data). Core will not deteriorate in a fire until the temperature reaches the melting point of glass.
  • "Outward cast" of helix keeps duct core from shrinking up inside insulation and jacket, resulting in less waste.
  • Heavy woven and coated fiberglass cloth core will not "blow-out" and eliminates costly call-backs.
  • Lower installed cost.
  • Available through broad national distribution.

    Thermaflex warrants that the M-KC Flexible Air Duct will be free from defects in materials and factory workmanship for life. This warranty covers the flexible duct, materials and labor.
