127mm (5") x 10m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce fan and airflow noise transmitted through extraction and intake systems.

Ventilation fans are essential for controlling temperature, humidity and air exchange, but the noise they generate can travel through standard ducting. Air movement and turbulence within the duct can also contribute to the overall sound of an extraction system.

Mute Silent Ducting uses an insulated construction around the flexible inner airflow duct to help absorb transmitted sound. It provides a practical alternative to standard uninsulated flexible ducting where quieter ventilation is required.

With a 127mm (5") nominal diameter and 10m length, this version is particularly useful for longer ventilation runs, larger installations or projects requiring several shorter sections of acoustic ducting.

Why choose 127mm acoustic silent ducting?

  • Helps reduce ventilation noise - acoustic insulation helps absorb sound travelling through the ductwork.
  • 127mm / 5" diameter - suitable for compatible 5-inch ventilation equipment.
  • 10 metre length - ideal for longer duct runs or cutting into several shorter sections.
  • Acoustically insulated - designed for installations where reducing transmitted fan and airflow noise is important.
  • Flexible construction - easier to route around equipment and structural obstacles than rigid ductwork.
  • Suitable for extraction - use with compatible fans, carbon filters, silencers and exhaust routes.
  • Suitable for intake - can also be incorporated into appropriately designed fresh-air intake systems.
  • Ideal for indoor horticulture - helps reduce one of the most noticeable sources of grow room noise.
  • Cut to the required length - use the complete 10m run or divide it to suit the installation.

How does acoustic ducting reduce ventilation noise?

Standard flexible ducting provides an effective route for moving air, but it can also carry sound generated by the fan and turbulent airflow. That sound can travel along the duct and become audible at other points in the ventilation system.

Acoustic ducting surrounds the flexible inner duct with an insulating layer designed to help absorb transmitted sound. This can reduce the amount of fan and airflow noise carried along the duct run.

It is particularly useful on duct sections immediately before or after an extraction fan, between compatible ventilation components and on longer exhaust routes where transmitted noise may otherwise be noticeable.

Acoustic ducting is a noise-reduction component rather than a complete silencing solution. Fan motor noise, vibration, airflow velocity and the design of the overall ventilation system can all influence the final sound level.

Quieter 5-inch grow room ventilation

A correctly designed extraction system helps remove excess heat and humidity while maintaining regular air exchange within an indoor growing environment.

Where the extraction system operates continuously or for extended periods, fan and airflow noise can become particularly noticeable. Using acoustic ducting helps reduce sound transmitted through the ductwork while retaining the flexibility needed for practical grow room installations.

The 10m length is especially useful where the extraction point is positioned some distance from the growing area or where several sections of 127mm acoustic ducting are required within the same installation.

Maintaining airflow through a 10m duct run

Longer duct runs create more airflow resistance than short, direct installations. For this reason, careful routing becomes increasingly important when using a substantial length of flexible ducting.

Use only the length required and extend the duct sufficiently rather than leaving unnecessary sections heavily compressed. This helps reduce excessive internal corrugation and provides a less restrictive path for moving air.

Avoid crushed sections and very tight bends wherever possible. Where a significant change in direction is required, an appropriately sized rigid elbow can provide a cleaner airflow route than forcing flexible ducting around an extremely tight corner.

Carbon filters, silencers, reducers, bends and other fittings also add resistance. The complete duct route should therefore be considered when selecting and setting up an extraction fan.

Installing 127mm Mute Silent Ducting

Measure the required route before cutting the ducting. The full 10m length can be used for a longer continuous run or divided into shorter sections depending on the ventilation layout.

When connecting to a compatible fan, carbon filter, silencer or rigid fitting, secure the inner duct to the connection using an appropriately sized duct clamp or clip.

Arrange the insulation and outer covering neatly around the connection. Suitable HVAC foil tape can also be used where additional sealing is required.

Longer insulated duct runs should be supported at suitable intervals. Avoid allowing the full weight of the ducting to hang directly from a fan, carbon filter or other ventilation component.

Compatible 127mm / 5" ventilation equipment

This ducting is intended for nominal 127mm (5") round ventilation installations and can be used with appropriately sized components including:

  • 127mm / 5" inline extraction fans
  • 127mm / 5" carbon filters
  • 127mm / 5" acoustic silencers
  • Compatible rigid round ducting
  • 127mm / 5" elbows and bends
  • 127mm / 5" straight connectors
  • Compatible reducers and adapters
  • Suitable duct clamps and clips

Always check the actual connection diameter of adjoining equipment before installation. Nominal metric and imperial ventilation sizes are frequently used together, but exact connection dimensions can vary slightly between manufacturers.

127mm (5") Mute Silent Ducting FAQs

What is acoustic ducting?

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

What size is this ducting?

It has a nominal diameter of 127mm, approximately 5 inches, and is supplied in a 10m length.

Is this suitable for a 5-inch extraction fan?

Yes, provided the fan has a compatible nominal 127mm / 5" connection.

Will acoustic ducting completely silence an extraction fan?

No. It helps reduce noise transmitted through the ductwork, but fan motor noise, vibration and airflow can still contribute to the overall sound level.

Is acoustic ducting quieter than standard flexible ducting?

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

Can I connect this ducting to a carbon filter?

Yes. It can be used with compatible 127mm / 5" carbon filters, extraction fans and other appropriately sized ventilation components.

Can it be used with an acoustic silencer?

Yes. Acoustic ducting and a compatible ventilation silencer can be used together where further reduction of transmitted ventilation noise is required.

Can I cut the 10m duct into shorter sections?

Yes. The ducting can be cut to suit the installation using suitable tools, taking care when cutting the flexible inner duct, reinforcement and surrounding insulation.

Can this ducting be used for air intake?

Yes. It can be incorporated into compatible intake systems as well as extraction installations.

Does a 10m duct run affect airflow?

Longer duct runs create more resistance than short runs. The actual effect depends on the fan, bends, filters and other components, so unnecessary excess ducting should be avoided.

Should acoustic ducting be fully extended?

It should be extended sufficiently for the required route rather than left heavily compressed. This helps reduce excessive internal corrugation and unnecessary airflow resistance.

Can I bend the ducting around corners?

Yes. Its flexible construction allows changes in direction, although very tight bends that crush or significantly restrict the inner duct should be avoided.

How should the ducting be secured?

Secure the inner duct to compatible fittings using an appropriately sized duct clamp or clip. Suitable HVAC foil tape can be added where further sealing is required.

Is 127mm acoustic ducting suitable for grow rooms?

Yes. It is particularly useful for indoor horticultural installations using compatible 5-inch extraction equipment where reducing ventilation noise is desirable.

How else can I reduce grow room extraction noise?

Use correctly sized ducting, minimise unnecessary bends, isolate fan vibration and consider suitable fan-speed control and compatible acoustic silencers where appropriate.
