Semi-flexible Stainless Steel Ventilation Duct

STAL FLEX ducts are made by coiling 60 mm-wide stainless steel strips. This flexible duct type is designed for building ventilation ducts which require resistance to high temperature and chemicals, and flexible connections with the equipment and components of the ventilation system. The ducts can also be used for connecting gas stoves in fireplace air heating systems.

Key Features

  • Material: Stainless steel 1.4404/316L, resistant to high temperatures and chemicals.
  • Packaging: 3-metre sections.
  • Flexibility: The minimum duct bending radius is 2.5 times the duct diameter (R = 1.5D).
  • Temperature range: From -30°C to +500°C.
  • Max. humidity: 95%.
  • Maximum acceptable static pressure: 2000 Pa.
  • Maximum acceptable static vacuum: 1000 Pa.
  • Recommended operating velocity: max. 7 m/s.
  • Maximum flow velocity: 25 m/s.
  • Fire resistance: non-flammable.
