Loading…Ventilation pipe
Ventilation pipe is used to build air ducts within ventilation and air extraction systems. A correctly selected pipe diameter and duct route help maintain sufficient airflow, lower resistance and a neat technical finish.
At Hewa, you will find ventilation pipe for installers, service technicians, business customers and DIY users. When selecting the right pipe, check diameter, material type, duct length, bends, free airflow, connection, sealing, condensation risk and the complete layout of the ventilation system.

Selecting ventilation pipe
Ventilation pipe is used to move air in a controlled way between extraction points, ventilation points, roof terminals, wall terminals and grilles. The pipe forms the basis of the air duct and, together with bends, fittings and connections, determines how efficiently air can be extracted. A correctly selected ventilation pipe helps prevent unnecessary air resistance, noise and leakage in the duct route.
The right choice depends on diameter, duct length, airflow, material type, mounting position and connection to other ventilation components. For the broader category, also review air exhaust material for ventilation. For roof finishing, roof terminal is important. For visible finishing of air openings, ventilation grille may be relevant.
Important when choosing ventilation pipes
- Check the correct pipe diameter and connection size of the ventilation system
- Match diameter to airflow, duct length and required air extraction
- Limit sharp bends, restrictions and unnecessarily long duct routes
- Select suitable fittings, connectors, grilles and terminals
- Check sealing, fixing, condensation and free air passage
- Install the pipe firmly, straight and as service-friendly as possible
- Always check the technical requirements of the ventilation system, extraction point and terminal
Building air ducts neatly and efficiently
A ventilation pipe must be able to move enough air without unnecessary resistance. If the diameter is too small or the duct route contains too many bends, airflow may decrease and noise levels may increase. That is why it is important to plan the route in advance and use matching diameters, smooth transitions and firm connections wherever possible.
During installation, the ventilation pipe must connect properly to fittings, roof terminals, wall terminals or ventilation grilles. Open seams or poorly fitting connections can cause air leakage and reduce the performance of the ventilation system. Condensation also requires attention, especially when warm and humid air is extracted through colder spaces or outdoors.
For installers, it is sensible to assess the complete duct route. Consider extraction capacity, duct length, bends, backdraft, fixing points, cleanability, fire safety, roof or façade finishing and maintenance access. A carefully built route provides better air extraction, less risk of noise nuisance and a neater technical finish.
Frequently asked questions about ventilation pipe
What is ventilation pipe used for?
Ventilation pipe is used to move air within a ventilation or air extraction system. The pipe connects extraction points, ventilation points, grilles, fittings and roof or wall terminals.
Which ventilation pipe diameter do I need?
The correct diameter depends on airflow, duct length, ventilation type, connection and the number of bends in the route. Always check the technical requirements of the ventilation system.
Why should sharp bends be avoided?
Sharp bends increase air resistance and can result in lower airflow and more noise. A duct route that is as straight as possible usually works more efficiently.
Does ventilation pipe need to be sealed?
Yes, proper sealing is important to prevent air leakage. Poorly connected pipes or open seams can reduce ventilation capacity and cause noise or condensation issues.
What should an installer check during installation?
Check diameter, duct route, connection, sealing, fixing, bends, condensation risk, free air passage, cleanability and connection to roof terminal, wall terminal or ventilation grille.
