Fantech Iris Damper IR4, 4" Duct, Manual

Thermaflex S-LP-10, non-insulated flex ducts are ideal for low, medium pressure heating and cooling systems where insulated ducts are not required. These HVAC ducts feature a strong woven fiberglass fabric with a flame retardant coating that is bonded to a corrosion resistant steel wire coil for secure air sealing. Spiral ducts will not unravel when cut and have a self-extinguishing inner core that will not support flames. Temperature range is from -20F to 250F. Ducts measure 2-14" in diameter. Greenguard certified. 10 Year Limited Warranty.

Two silencers can be used together in installations where noise reduction is critical. For the most effective noise reduction, the silencer should be fitted immediately behind a fan or bend.

Thermaflex M-KE HVAC ducts have a vinyl coated spring steel wire coil construction that is ideal for low, medium pressure heating and cooling environments. These highly efficient flex ducts feature a core that is bonded to the steel wire coil to support the fiberglass insulation. Duct insulation is available in three different R-values for varied thickness: R-4.2, R-6.0 and R-8.0. The acoustically rated, polyethylene inner liner on these HVAC ducts eliminates noise and easily expands. Spiral ducts are mold and mildew resistant. Temperature range is from -20F to 200F and -20F to 250F ...
