The combination of standard external helix as scuff guard and non-glue construction results in the industry standard high-temperature duct.Material: Fiberglass/Silicone
Construction: Mechanical bond, corrosion resistant helix
Diameters: 2” to 24” I.D.Bend radius: 1.5 X I.D.Length: 25 feet
Compression Ratio: 5:1
Temperature Range: -65°F (-54°C) to +500°F (260°C) intermittent
Color: Metallic greyApplications
*A negative pressure fan system with ambient air inlet is recommended to maximize effectiveness and life of duct. It is important to size the duct diameter according to the exhaust output.
