Thermaflex® S-LP-10 non-insulated Class 1 connector isdesigned for use in all pressure cooling and heatingsystems. It is used in either supply or returnsections: for branch ducts and duct connections to orbetween mixing units, induction units, control orterminal units, and diffusion devices, including light troffers.Thermaflex S-LP-10 duct provides economical meansfor handling misalignment between system componentsand ducts around obstacles where fabricated and fittedducts are difficult and costly to install. This duct isequally useful when making system extensions orchanging conditioned zones now or in the future.Thermaflex S-LP-10 duct offers further economy ofinstalled cost, for example, as a return duct withinconditioned spaces or in any zone where the functionof insulated duct is not required.
