254mm (10") x 10m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce fan and airflow noise in high-capacity extraction and intake systems.

Powerful ventilation equipment can generate considerable noise from both the fan and the movement of air through the ductwork. This insulated ducting provides a practical way to reduce sound transmission while retaining the flexibility and straightforward installation of conventional flexible duct.

The flexible inner airflow duct is surrounded by an acoustic insulation layer that helps absorb sound travelling along the ventilation system. This makes it particularly useful in grow rooms and indoor horticultural environments where extraction equipment may operate for extended periods.

Supplied in a generous 10 metre length with a nominal 254mm / 10" diameter, the duct can be used as one extended run or cut into shorter sections to suit the installation.

Why choose 254mm acoustic silent ducting?

  • Helps reduce ventilation noise - acoustic insulation helps absorb fan and airflow sound transmitted through the ductwork.
  • 254mm / 10" diameter - suitable for compatible high-capacity fans, carbon filters and ventilation fittings.
  • 10 metre length - ideal for longer duct runs or cutting into several individual sections.
  • Acoustically insulated construction - designed for quieter ventilation than basic uninsulated flexible ducting.
  • Flexible design - makes routing around equipment and through ventilation installations straightforward.
  • Extraction or intake - suitable for moving extracted air out of an environment or routing fresh air into it.
  • Cut to the required length - use only the amount of ducting necessary for each part of the system.
  • Suitable for indoor horticulture - particularly useful with larger grow room ventilation systems where noise control is important.

How does acoustic ducting reduce ventilation noise?

Ventilation noise does not only originate directly from an extraction fan. Fan sound, vibration and turbulent airflow can travel through ordinary ductwork and become audible at other points in the ventilation route.

Acoustic ducting surrounds the flexible inner air passage with an insulating layer designed to absorb transmitted sound. This helps reduce the amount of fan and airflow noise travelling along the duct run.

It can be particularly useful immediately before or after an extraction fan, between a fan and carbon filter, or along longer ventilation routes where transmitted sound needs to be controlled.

Acoustic ducting is designed to reduce ventilation noise rather than make an extraction system completely silent. Fan design, fan speed, airflow velocity, vibration, duct routing and installation quality will all influence the final noise level.

Designed for high-capacity grow room ventilation

Larger grow rooms and controlled horticultural environments can require substantial air movement to manage heat, humidity and general air exchange. As ventilation capacity increases, controlling the associated noise becomes increasingly important.

The 254mm / 10" diameter is suitable for compatible high-volume extraction equipment, while the insulated construction helps reduce sound transmitted through the ducting.

It can be incorporated into complete ventilation systems using compatible inline fans, carbon filters, metal duct fittings, reducers, bends and other appropriately sized components.

Maintaining good airflow through flexible ducting

Correct installation is important because every length of duct, bend and fitting introduces resistance to airflow. This becomes especially relevant with longer ventilation runs.

Extend the duct sufficiently rather than leaving unnecessary sections heavily compressed. A more fully extended inner duct provides a smoother airflow path and can help reduce avoidable turbulence and resistance.

Keep the route as short and direct as the installation allows. Avoid crushing the duct and minimise tight bends, with gradual changes in direction preferable wherever possible.

Although this product provides 10 metres of ducting, there is no requirement to use the full length. Cutting each section to the amount actually required can help create a cleaner and more efficient ventilation installation.

Installing 254mm Mute Silent Ducting

Check that the fan, carbon filter and other ventilation fittings have compatible nominal 254mm / 10" connections before installation.

Fit the flexible inner duct securely over the ventilation connection and fasten it using an appropriately sized duct clamp or suitable fixing. HVAC foil tape can be used where additional sealing is required.

Arrange the acoustic insulation and outer covering neatly around the completed joint so that the insulating layer remains as continuous as practical.

Long duct runs should be supported at suitable intervals. Avoid allowing the full weight of a long section of ducting to hang directly from the extraction fan, carbon filter or another ventilation component.

254mm (10") Mute Silent Ducting FAQs

What is acoustic ducting?

Acoustic ducting is flexible ventilation duct surrounded by insulation designed to help reduce sound transmitted through a ventilation system.

What size is this ducting?

This version has a nominal diameter of 254mm, equivalent to 10 inches, and is supplied in a 10 metre length.

Is this suitable for a 10-inch extraction fan?

Yes, provided the fan has a compatible nominal 254mm / 10" connection. Check the fan connection dimensions before installation.

Can it be connected to a 10-inch carbon filter?

Yes. It can be used with a compatible 254mm / 10" carbon filter as part of an appropriately sized extraction system.

Does acoustic ducting make an extraction fan silent?

No. Acoustic ducting helps reduce noise transmitted through the ductwork, but it cannot completely eliminate fan motor noise, vibration or the sound created by moving air.

Is acoustic ducting quieter than standard flexible ducting?

Its insulated construction is specifically intended to reduce transmitted ventilation noise compared with basic uninsulated flexible ducting.

Can this ducting be used for intake as well as extraction?

Yes. It can be incorporated into compatible fresh-air intake systems as well as extraction systems.

Can I cut the 10m duct into shorter lengths?

Yes. The ducting can be cut to suit the installation, making the 10m version useful when several individual duct sections are required.

Do I need to use the entire 10 metre length?

No. Use only the amount required. Keeping ventilation routes reasonably short and direct generally helps minimise unnecessary resistance.

Does a longer duct run reduce airflow?

Longer duct runs introduce additional resistance. Bends, fittings and compressed flexible duct can add further resistance, so ventilation systems should be planned with the total duct route in mind.

Do bends in the duct affect extraction performance?

Yes. Tight bends can increase airflow resistance, so smooth and gradual changes in direction are preferable where the installation allows.

Should flexible acoustic ducting be fully extended?

It should be extended sufficiently for the required run rather than left unnecessarily compressed. This helps provide a smoother internal path for airflow.

Where is the best place to use acoustic ducting?

It can be used throughout a compatible ventilation route. Sections immediately around powerful extraction fans can be particularly useful where reducing transmitted fan noise is a priority.

Does a 10m run need supporting?

Yes. Longer duct runs should be supported appropriately rather than allowing their weight to hang entirely from the fan, filter or connecting fittings.

How can I make a grow room extraction system quieter?

Acoustic ducting can form part of a quieter installation alongside sensible duct routing, correctly sized fans and filters, vibration isolation, suitable fan-speed control and ventilation silencers.
