Thermaflex® M-KE air duct is a thermally insulated, fully lined, flexible air duct designed for use in all 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.
Thermaflex M-KE air duct provides economical means for handling misalignment between system components and ducting around obstacles where fabricated and fitted ducts are difficult and costly to install.
Thermaflex air duct is equally suitable for new jobs or refit work and is especially useful when making system extensions or for changing conditioned zones, now or in the future. Compliance with NFPA Standards lets you install lengths longer than the limitation applying to connectors.
Thermaflex M-KE is a highly efficient duct because the liner, in combination with the reinforced, metallized vapor barrier, provides a double air seal.
