152mm (6") x 10m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce the transmission of fan and airflow noise through extraction and intake systems.

Ventilation systems can transmit a considerable amount of sound through standard ducting. Noise generated by the fan, together with turbulence and fast-moving air, can travel along the duct run and become audible at the inlet or outlet.

This acoustic ducting uses an insulated construction around the flexible inner airflow duct to help absorb transmitted sound. It provides a practical upgrade from standard uninsulated flexible ducting where quieter ventilation is required.

With a 152mm (6") nominal internal diameter and generous 10m length, it is particularly useful for larger installations, longer duct runs or projects requiring several shorter sections of acoustic ducting.

Why choose 152mm acoustic silent ducting?

  • Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ducting system.
  • 152mm / 6" diameter - suitable for compatible 6-inch ventilation equipment.
  • 10 metre length - ideal for longer ventilation runs or cutting into multiple sections.
  • Insulated construction - designed for applications where reducing transmitted ventilation noise is important.
  • Flexible design - easier to route around equipment and structural obstacles than rigid ductwork.
  • Suitable for extraction - ideal for connecting 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 tackle 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 offers relatively little acoustic isolation. Sound produced by an extraction fan and turbulent airflow can therefore travel along the same route.

Acoustic ducting adds a layer of sound-absorbing insulation around the inner flexible duct. This helps reduce the amount of noise transmitted through and along the ventilation system.

It can be particularly effective on duct sections immediately before or after an extraction fan, between a carbon filter and fan, or along longer duct runs where ventilation noise would otherwise be noticeable.

Acoustic ducting should be regarded as a noise-reduction component rather than a complete silencing solution. Fan vibration, motor noise, airflow velocity and other components can also contribute to the overall sound produced by an extraction system.

Quieter 6-inch grow room ventilation

152mm-class ventilation equipment is widely used in indoor horticulture where substantial airflow is required for managing heat, humidity and air exchange.

As extraction capacity increases, fan and airflow noise can become more noticeable. Acoustic ducting helps reduce sound transmitted through the ductwork while retaining the flexibility required to route the system around the growing environment.

The 10m length makes this version particularly useful for larger grow rooms, longer extraction routes and installations where the fan or exhaust point is positioned some distance from the growing area.

Building a quieter extraction system

The best results are achieved by considering noise throughout the complete ventilation installation. Sound can originate from the fan motor, vibration, turbulent airflow and air travelling at high velocity through restrictive ductwork.

Acoustic ducting addresses sound transmitted through the duct run, while correctly sized fans and ducting help prevent excessive airflow velocity and resistance.

Where additional noise reduction is required, acoustic ducting can be combined with compatible ventilation silencers, suitable fan-speed control and vibration-isolating mounting methods.

Maintaining airflow through a 10m duct run

Longer duct runs create more resistance than short runs, so installation becomes particularly important when using a substantial length of flexible ducting.

Use only the length required and extend the flexible inner duct sufficiently to avoid unnecessary compression. Excessive internal corrugation, tight bends and crushed sections all increase resistance to airflow.

Keep the route as straight as the installation allows. Where a substantial direction change is required, an appropriately sized rigid metal elbow can provide a cleaner airflow route than forcing the flexible duct around an extremely tight corner.

When planning a long extraction run, remember that carbon filters, silencers, bends, reducers and other fittings also contribute to the total resistance the fan must overcome.

Installing 152mm acoustic ducting

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

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

Arrange the insulation and outer covering neatly around the joint. Where minimising air leakage is important, suitable HVAC foil tape can also be used as part of the connection and sealing process.

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

Compatible 152mm / 6" ventilation equipment

This ducting is designed for nominal 152mm (6") ventilation installations and can be used alongside appropriately sized components including:

  • 152mm / 6" inline extraction fans
  • 152mm / 6" carbon filters
  • 152mm / 6" acoustic silencers
  • Compatible rigid round ducting
  • 152mm / 6" elbows and bends
  • 152mm / 6" straight connectors

152mm (6") Mute Silent Ducting FAQs

What is acoustic ducting?

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

What size is this silent ducting?

It has a nominal internal duct diameter of 152mm, approximately 6 inches, and is supplied in a 10m length.

Is this suitable for a 6-inch extraction fan?

Yes, provided the fan has a compatible nominal 152mm / 6" connection.

Will acoustic ducting completely silence my extraction fan?

No. It helps reduce noise transmitted through the ductwork, but fan motor noise, vibration and airflow can still be audible.

Is acoustic ducting quieter than standard flexible ducting?

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

Can I use it with a carbon filter?

Yes. It can be used with a compatible 152mm / 6" carbon filter as part of an extraction system.

Can acoustic ducting be used with a ventilation silencer?

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

Can the 10m duct be cut into shorter lengths?

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

Can I use this ducting for air intake?

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

Does a 10m duct run reduce airflow?

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

Should acoustic ducting be stretched out?

It should be extended sufficiently for the required run 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, but very tight bends that crush the inner duct should be avoided.

How should acoustic ducting be secured?

The inner duct can be secured to compatible ventilation connections using appropriately sized duct clamps or clips, with suitable HVAC foil tape used where additional sealing is required.

Is 152mm silent ducting suitable for grow rooms?

Yes. It is particularly useful for indoor horticultural installations where 6-inch extraction equipment is used and reducing ventilation noise is desirable.

What else can I do to reduce grow room extraction noise?

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