Tips on Ventilation Ducting Selection

  • Choose the shortest route to the outside vent point
  • Use as few bends as possible
  • Use proper duct sealant especially where the duct sections are inaccessible for maintenance
  • Choose an appropriate duct size to suit the extract capacity of your fan
  • Round ducting is the most efficient for air travel if you have the room
  • Rigid duct is more efficient than flexible duct
  • If flexible duct must be used then try to ensure it is kept taut and straight as possible
