127mm (5") x 5m Acoustic Ducting is an insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through extraction and intake systems.
Ventilation fans generate sound from both the fan itself and the movement of air through the system. Standard uninsulated ducting can allow this noise to travel along the ventilation route, while acoustic ducting incorporates an insulating layer around the inner duct to help absorb transmitted sound.
This makes it particularly useful for indoor horticulture, propagation areas and controlled growing environments where ventilation equipment may operate for extended periods and reducing unnecessary noise is desirable.
Supplied in a 5 metre length with a nominal 127mm / 5" diameter, it can be connected to compatible fans, carbon filters and ventilation fittings. The flexible construction allows the duct to be routed around equipment and cut to the required length during installation.
Why choose 127mm acoustic ducting?
- Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
- 127mm / 5" diameter - suitable for compatible 5-inch ventilation equipment.
- 5 metre length - suitable for complete duct runs or cutting into several shorter sections.
- Insulated construction - designed to reduce transmitted sound compared with basic uninsulated flexible ducting.
- Flexible installation - straightforward to route around fans, filters and other ventilation equipment.
- Suitable for extraction - ideal for carrying extracted air away from controlled growing areas.
- Suitable for intake - can also be incorporated into compatible fresh-air intake systems.
- Cut to length - install only the amount required for a clean and efficient duct route.
- Suitable for horticultural environments - ideal for propagation, growing and other controlled-environment applications.
How does acoustic ducting reduce noise?
Noise within a ventilation system can come from the fan motor, vibration and turbulent air moving through the ductwork. Some of this sound can travel along ordinary flexible duct and become noticeable elsewhere in the installation.
Acoustic ducting surrounds the flexible inner airflow passage with insulation designed to absorb transmitted sound. This helps reduce the amount of fan and airflow noise travelling through the duct route.
It can be particularly useful around extraction fans, between compatible fans and carbon filters, and along sections of ventilation duct where transmitted noise needs to be controlled.
Acoustic ducting is intended to reduce transmitted noise rather than make a ventilation system completely silent. Fan design, fan speed, airflow velocity, vibration and installation quality all contribute to the final noise level.
Acoustic ducting for indoor horticulture
Reliable ventilation helps manage temperature, humidity and air exchange within controlled growing environments. Extraction and intake equipment can, however, become a significant source of noise when operating continuously or at higher fan speeds.
Acoustic ducting provides a practical way to reduce sound transmission while maintaining the flexibility needed to connect ventilation equipment and route air around an installation.
The 127mm / 5" size is suitable for compatible ventilation systems using appropriately sized inline fans, carbon filters, connectors and other round duct fittings.
Getting the best airflow from acoustic ducting
Good installation is important for maintaining ventilation performance. Flexible ducting should be extended sufficiently rather than left heavily compressed, helping create a smoother internal path for moving air.
Keep the duct route as short and direct as practical. Tight bends, crushed sections and unnecessary changes in direction create additional resistance and can reduce the effective airflow delivered by the fan.
Where the duct needs to change direction, use gradual bends wherever possible. The supplied 5m length can be cut so that only the amount actually required is installed.
Installing 127mm acoustic ducting
Before installation, check that the fan, carbon filter and other ventilation components have compatible nominal 127mm / 5" connections.
Fit the flexible inner duct securely over the ventilation connection and fasten it using a suitably sized duct clamp or appropriate fixing. HVAC foil tape can also be used where additional sealing is required.
Arrange the surrounding insulation and outer covering neatly around the completed connection so that the acoustic layer remains as continuous as practical.
Support longer sections appropriately rather than allowing the entire weight of the ducting to hang directly from a fan, filter or connecting fitting.
Compatible ventilation equipment
- 127mm / 5" inline extraction fans
- Compatible 5-inch carbon filters
- Ventilation silencers
- Rigid round ductwork
- Duct connectors and couplers
- Elbows and bends
- Reducers and adapters
- Duct clamps and fixing accessories
Check the actual connection diameter of individual ventilation components before installation, as dimensions can vary slightly between manufacturers.

127mm (5") Acoustic Ducting FAQs
What size is this acoustic duct?
This version has a nominal diameter of 127mm, equivalent to 5 inches, and is supplied in a 5 metre length.
Is this suitable for a 5-inch extraction fan?
Yes, provided the fan has a compatible nominal 127mm / 5" connection.
Can it be used with a 5-inch carbon filter?
Yes. It can be used with compatible 127mm / 5" carbon filters and extraction fans as part of an appropriately sized ventilation system.
Does acoustic ducting reduce fan noise?
It helps reduce fan and airflow sound transmitted along the ductwork. It does not completely eliminate noise generated directly by the fan.
Is acoustic ducting quieter than ordinary flexible ducting?
Its insulating layer is specifically intended to absorb transmitted sound, making it useful where reducing ventilation noise is important.
Can acoustic ducting be used for horticultural extraction?
Yes. It is well suited to indoor horticultural ventilation systems where temperature, humidity and air exchange need to be managed while keeping transmitted ventilation noise under control.
Can it be used for air intake?
Yes. Acoustic ducting can be incorporated into compatible intake as well as extraction systems.
Can I cut the 5m duct into shorter sections?
Yes. It can be cut to suit the required ventilation route or divided into several individual sections.
Should flexible acoustic ducting be fully extended?
It should be extended sufficiently for the installation rather than left unnecessarily compressed. This helps create a smoother internal path for airflow.
Do bends in acoustic ducting affect airflow?
Yes. Tight bends increase resistance and turbulence, so smooth and gradual changes in direction are preferable wherever possible.
Does duct length affect extraction performance?
Every length of duct introduces some resistance. Longer runs, multiple bends and additional fittings can therefore reduce the effective airflow of a ventilation system.
Where should acoustic ducting be installed?
It can be used throughout a compatible ventilation route. Sections around the extraction fan can be particularly useful where transmitted fan noise is a concern.
How should acoustic ducting be secured?
Use appropriately sized duct clamps or suitable ventilation fixings, with HVAC foil tape where additional sealing is required.
How can horticultural ventilation noise be reduced further?
Correct fan sizing, sensible duct routing, vibration isolation, suitable fan-speed control and ventilation silencers can be combined with acoustic ducting to create a quieter overall system.
