Unit price perEstimated delivery between November 01 and November 03.
102mm (4") x 10m COMBI Ducting is a flexible reinforced ventilation duct designed for reliable air movement in extraction and intake systems.
COMBI ducting combines the flexibility required for straightforward installation with a more robust outer construction than basic foil ducting. It is well suited to ventilation systems where ductwork needs to negotiate equipment, corners or other obstacles while remaining easy to position.
The flexible construction allows the duct to be extended, routed and cut to the required length. The generous 10 metre length is particularly useful for longer ventilation runs or where several shorter sections are required from one length.
With a nominal diameter of 102mm / 4", it is designed for use with compatible fans, filters, connectors, reducers and other round ventilation components.
Why choose COMBI ducting?
- Reinforced flexible construction - designed to provide a more robust ducting solution while retaining installation flexibility.
- 102mm / 4" diameter - suitable for compatible 4-inch round ventilation systems.
- 10 metre length - ideal for longer duct runs or cutting into several shorter sections.
- Suitable for extraction - designed for carrying extracted air through a compatible ventilation system.
- Suitable for air intake - can also be incorporated into compatible fresh-air intake systems.
- Flexible routing - useful where ductwork needs to pass around equipment or changes in direction.
- Can be cut to length - use only the amount required for each installation.
- Compatible with common ventilation equipment - suitable for matching fans, filters and round duct fittings.
- Easy to secure - compatible connections can be mechanically fixed using appropriately sized ducting clips or clamps.
Flexible ducting for controlled environment ventilation
Effective ventilation depends on moving air between components with as little unnecessary resistance as practical. Flexible COMBI ducting makes it easier to create a complete duct route without requiring rigid sections throughout the installation.
It is suitable for connecting compatible extraction fans, air filters and ventilation fittings in propagation areas, growing areas, nurseries and other controlled horticultural environments.
The 10 metre length provides additional flexibility for larger installations, longer equipment connections or projects where multiple shorter sections of 102mm ducting are required.
Installing 102mm COMBI ducting
Extend the ducting to the required length and plan the route before making the final connections. Keeping the duct run reasonably direct helps reduce unnecessary airflow resistance.
Avoid excessively tight bends, severe compression or crushing the duct, as restrictions in the airflow path can reduce ventilation performance.
Fit the duct securely over compatible 102mm connections and use an appropriately sized ducting clip or clamp to create a reliable mechanical fixing. Suitable HVAC foil tape can also be used where additional air sealing is required.
Longer sections should be supported where necessary to prevent excessive sagging and to maintain a clean, unrestricted airflow path between components.
Getting the best airflow from flexible ducting
Although this product is supplied as a 10 metre length, there is no requirement to use the entire length in a single duct run. Using only the amount required for the installation can help reduce unnecessary resistance.
For efficient airflow, use the shortest practical route, minimise unnecessary bends and avoid leaving excessive compressed duct between components. Where a direction change is required, a gradual bend is preferable to a tightly folded section.
Fan performance should be considered across the complete ventilation system, including duct length, bends, filters, silencers, reducers and other fittings installed in the airflow path.

102mm (4") x 10m COMBI Ducting FAQs
What diameter is this COMBI ducting?
This version has a nominal diameter of 102mm, commonly referred to as 4-inch ducting.
How long is the ducting?
This product is supplied as a 10 metre length.
Can COMBI ducting be used with a 4-inch extraction fan?
Yes, it can be used with compatible fans designed for nominal 102mm / 4" ventilation connections.
Can it connect to a carbon filter?
Yes. The ducting can be connected to a compatible 102mm carbon filter or to suitable adapters where different component sizes are being combined.
Can COMBI ducting be used for air intake?
Yes. It can be used for both extraction and intake applications within a compatible ventilation system.
Can I cut the 10m duct to shorter lengths?
Yes. Flexible ducting can be cut to suit the installation, making the 10 metre length useful where several shorter sections are required.
Do I need to use the full 10 metres?
No. Use only the length required. Keeping duct runs as short and direct as practical generally helps minimise resistance to airflow.
How should COMBI ducting be attached?
Fit the duct over a compatible connection and secure it with an appropriately sized ducting clip or clamp. HVAC foil tape can be added where further air sealing is required.
Can the ducting bend around obstacles?
Yes. Its flexible construction allows it to be routed around equipment and obstacles, although gradual bends are preferable to tight folds or sharp restrictions.
Do bends in flexible ducting reduce airflow?
Excessive duct length, tight bends and compressed sections can increase resistance to airflow, so a direct and unrestricted route is preferable.
Can this ducting be used with reducers and connectors?
Yes. Compatible round connectors, reducers, elbows and other ventilation fittings can be incorporated into the duct system as required.
Should flexible ducting be fully extended?
Where practical, extending the duct rather than leaving it heavily compressed helps create a smoother airflow path and reduces unnecessary restriction.
Should a 10m duct run be supported?
Yes. Longer sections should be supported where necessary to help prevent excessive sagging and maintain the intended duct route.
Is COMBI ducting the same as acoustic ducting?
No. COMBI ducting is primarily a reinforced flexible air duct. Acoustic ducting incorporates additional insulation specifically intended to help reduce the transmission of fan and airflow noise.
