Flat Oval Tubes

The Helical Flat Ovel Duct is precision formed on automatic machines and has all the superior construction features of the Helical Round Duct. It has been designed to:-

  • provide an engineered duct for areas with low head room and restricted locations which will not accommodate a round duct.
  • provide a duct without sharp corners so that air turbulence is minimised.
  • Suitable for low Roof heights.
  • Typical variation of flat oval duct with identical circumference which can be made from the same diameter circular tube.
