Description

Product Highlights

Thermaflex® G-KM air duct is a thermally insulated, fully lined, flexible air duct designed for use in low to medium pressure cooling and heating systems. It is used in either supply or return sections: for branch ducts and branch connections to or between mixing units, induction units,control or terminal units and diffusion devices, including light troffers. It provides economical means for handling misalignment between systems components and ducting around obstacles where fabricated and fitted ducts are difficult and costly to install. It is equally suitable for new jobs or refit work and is especially useful when making systems extensions or for changing conditioned zones, now or in the future.
Compliance with NFPA Standards lets you installlengths longer than the limitation applying to connectors. It is a highly efficient part of the total duct system because the smooth liner, the ample insulation and tough vapor barrier provide good air flow, thermal insulation and a double airseal. The heavy spring steel wire helix assures dimensional stability and more efficient air delivery particularly in tight radius bends.
