317mm (12.5") x 5m Mute Silent Ducting is a large-diameter acoustically insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through high-volume extraction and intake systems.
Large extraction systems can move substantial volumes of air, but increased airflow can also make ventilation noise more noticeable. This insulated ducting provides a practical way to reduce sound transmission through the ductwork while maintaining the flexibility required for installation around fans, filters and other ventilation equipment.
The flexible inner airflow duct is surrounded by an acoustic insulation layer that helps absorb transmitted sound. This makes it particularly useful for larger grow rooms, horticultural facilities and other controlled environments where powerful ventilation equipment may operate for extended periods.
Supplied as a 5 metre length with a nominal 317mm / 12.5" diameter, it can be used as a continuous duct run or cut into shorter sections to suit the ventilation layout.
Why choose 317mm acoustic silent ducting?
- Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted along the ductwork.
- Large 317mm / 12.5" diameter - designed for compatible high-volume ventilation equipment.
- 5 metre length - suitable for substantial duct runs or cutting into shorter sections.
- Acoustically insulated construction - designed for quieter air movement compared with basic uninsulated flexible ducting.
- Flexible design - easier to route around equipment and obstacles than rigid ventilation ductwork.
- Suitable for extraction systems - use with appropriately sized fans, filters and ventilation fittings.
- Suitable for air intake - can also be incorporated into compatible fresh-air intake systems.
- Ideal for larger growing environments - useful where high airflow and noise control are both important considerations.
- Cut to suit - use only the length required for the installation to avoid unnecessary duct resistance.
How does acoustic ducting reduce ventilation noise?
Ventilation noise can originate from several sources, including the extraction fan itself, vibration and turbulent air moving through filters, bends and ductwork. Some of this sound can travel through ordinary flexible ducting and become noticeable elsewhere in the ventilation system.
Acoustic ducting surrounds the flexible inner air passage with insulation designed to absorb transmitted sound. This helps limit the amount of fan and airflow noise travelling along the duct route.
It is particularly useful immediately before or after extraction fans, between compatible ventilation components and along exhaust routes where reducing transmitted noise is desirable.
Acoustic ducting is designed to reduce noise rather than make an extraction system completely silent. Fan design, airflow velocity, vibration, duct length, bends and installation quality all influence the final sound level.
Large-diameter ducting for grow room ventilation
Larger indoor growing environments can require substantial airflow to remove excess heat and humidity and maintain a regular exchange of air. High-capacity extraction fans and carbon filters therefore commonly require larger-diameter ductwork.
The generous 317mm diameter allows this ducting to be paired with compatible large ventilation equipment while the acoustic insulation helps control noise travelling through the system.
It can be used for both extraction and intake routes, making it suitable for building complete ventilation systems in grow rooms and other indoor horticultural environments.
Maintaining efficient airflow
Correct duct installation is particularly important with high-volume ventilation systems. Every metre of duct, bend and fitting creates resistance that the extraction fan must overcome.
Extend flexible ducting sufficiently rather than leaving long sections heavily compressed. A properly extended duct creates a smoother internal airflow path and reduces unnecessary resistance.
Keep the route as short and direct as practical. Avoid crushing the duct, creating excessively tight bends or leaving unnecessary lengths coiled within the installation.
If the full 5m length is not required, the ducting can be cut to the appropriate length for the installation.
Installing 317mm Mute Silent Ducting
Plan the complete ventilation route before cutting or installing the duct. Check that the fan, filter and any connectors or fittings are compatible with the nominal 317mm / 12.5" duct size.
Connect the inner flexible duct securely around the equipment connection using a suitably sized duct clamp or fixing. Suitable HVAC foil tape can be used where additional sealing is required.
Arrange the insulation and outer covering neatly around the completed connection to maintain the acoustic layer as effectively as possible.
Because large-diameter insulated ducting can become relatively bulky over longer runs, provide suitable support rather than allowing its full weight to hang directly from a fan, carbon filter or other ventilation component.
Compatible ventilation equipment
The ducting can be incorporated into appropriately sized ventilation systems using components such as:
- Compatible large-diameter inline extraction fans
- Compatible carbon filters
- Ventilation silencers
- Rigid round ducting
- Metal duct connectors
- Elbows and bends
- Reducers and adapters
- Suitable duct clamps and fixing accessories
Always check the actual connection diameter of adjoining equipment before installation. Nominal ventilation sizes and the exact outside diameter of individual fittings can vary slightly between manufacturers.

317mm (12.5") Mute Silent Ducting FAQs
What size is this ducting?
This version has a nominal diameter of 317mm, approximately 12.5 inches, and is supplied in a 5m length.
What is 317mm ducting used for?
Its large diameter makes it suitable for compatible high-volume ventilation systems used in larger grow rooms and other environments requiring substantial extraction or intake airflow.
Does acoustic ducting make an extraction system silent?
No. It helps reduce sound transmitted through the ductwork but cannot completely eliminate fan motor noise, vibration or airflow noise.
Is it quieter than standard flexible ducting?
Its insulated construction is specifically intended to reduce transmitted ventilation noise compared with basic uninsulated flexible ducting.
Can I connect it to a carbon filter?
Yes, provided the carbon filter connection is compatible with the nominal 317mm / 12.5" duct size.
Can I use it with an extraction fan?
Yes. It is designed for use as part of a compatible ventilation system and can be connected to appropriately sized extraction equipment.
Can this ducting be used for air intake?
Yes. It can be used for compatible intake systems as well as extraction ductwork.
Can the 5m duct be cut?
Yes. It can be cut into the length or individual sections required for the ventilation installation.
Does the length of ducting affect airflow?
Yes. Longer duct runs create additional resistance, so using the shortest practical route can help maintain effective airflow.
Do bends in ducting reduce airflow?
Bends increase resistance, particularly when they are sharp or tightly compressed. Smooth, gradual changes in direction are preferable wherever possible.
Should flexible ducting be fully stretched?
It should be sufficiently extended for the required route rather than left heavily compressed, as excessive internal corrugation can increase airflow resistance.
How should large acoustic ducting be supported?
Use suitable supports along the duct route so that the weight of the ducting is not carried entirely by the extraction fan, filter or connecting fittings.
Can acoustic ducting be used with a ventilation silencer?
Yes. Combining acoustic ducting with a compatible ventilation silencer can provide additional control of sound transmitted through an extraction system.
What else can help reduce grow room extraction noise?
Good duct routing, suitable fan sizing, vibration isolation, appropriate fan-speed control and compatible silencers can all contribute to a quieter ventilation installation.
