Fastlec 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 it is important to try and ensure it is kept taut and as straight as possible
