Quadroflex® Flexible Duct System

Quadroflex Quadroflex is a flexible duct system used primarily in HVAC applications. The duct itself is a corrugated, single-ply, multi-sided, flat duct with interlocked seams, folded flat and knurled for air tightness, strength, and flexibility. Its flexible nature allows Quadroflex to be used in tight areas where standard ducting may not fit. It’s available in numerous sizes and shapes and can also be custom built to client specifications.

Features:

  • Ducting is flexible in both the longitudinal and lateral axis.
  • Because of the variety of profiles, a minimum of installation space is required. Easily fits into installation shafts.
  • Provides a viable alternative for the transport of gas-type mediums in AC applications.
  • Can be formed to make transition connections to round duct.
