Product Highlights

Thermaflex® S-TL non-insulated flexible air duct is designed for use in all pressure cooling and heating systems. It is used in either supply or return sections: for branch ducts and duct connections to or between mixing units induction units, control or terminal units and diffusion devices, including light troffers.
Thermaflex S-TL 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. This duct is equally suitable for new jobs or refit work, and is especially useful when making system extensions or changing conditioned zones now or in the future.
Compliance with NFPA Standards lets you install lengths longer than the limitation applying to connectors.
Thermaflex S-TL air duct offers further economy of installed cost, for example, as a return duct within conditioned spaces or in any zone where the function of insulated duct is not required.
