A highly flexible duct made of fine wire reinforced (E-Glass ceramic cloth) that is chemically treated and coated. Ideal for higher temperature fume recovery.

Material: Alumina coated, textile glass fabric reinforced with a fine V4A wire.

Construction: Mechanical bond, galvanized steel helix (also available stainless steel helix)

Diameters: 3” to 24” I.D.

Length: 25 feet

Compression Ratio: 3”-4”=4:1

Temperature Range: -200°F (-129°C) to +1000°F (538°C). Intermittent

Color: Metallic grey


  • High temperature fume recovery
  • Scuff resistant
  • Flame resistant

*Air velocity should be less than 50 m/sec

*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.
