THERMAFLEX® S-LD duct is a non-insulated air connector 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-LD duct provides economical means for handing misalignment between system components and ducts 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. THERMAFLEX S-LD 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.
