£21.80

254mm (10") x 5m Mute Silent Ducting is an acoustically insulated flexible ventilation duct designed to help reduce fan and airflow noise in powerful extraction and intake systems.

High-capacity ventilation equipment can generate significant noise from the fan itself and from fast-moving air travelling through the ductwork. This insulated ducting provides a practical solution where quieter ventilation is required without sacrificing the flexibility of conventional flexible duct.

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

Supplied in a 5 metre length with a nominal 254mm / 10" diameter, it is suitable for compatible 10-inch fans, carbon filters and ventilation fittings and can be cut to the required length during installation.

Why choose 254mm acoustic silent ducting?

  • Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
  • 254mm / 10" diameter - suitable for compatible high-capacity ventilation equipment.
  • 5 metre length - provides plenty of duct for complete installations or several shorter sections.
  • Acoustically insulated construction - designed for quieter ventilation than basic uninsulated flexible ducting.
  • Flexible design - makes routing around fans, filters and other equipment straightforward.
  • Suitable for extraction - ideal for connecting compatible inline fans, carbon filters and exhaust routes.
  • Suitable for intake systems - can also be used to route fresh air into controlled growing environments.
  • Cut to size - use only the length required for the installation to help maintain efficient airflow.
  • Ideal for indoor horticulture - particularly useful where powerful ventilation needs to operate with reduced transmitted noise.

How does acoustic ducting reduce ventilation noise?

Noise from an extraction system does not only come directly from the fan. Fan noise, vibration and turbulent airflow can travel along ordinary ductwork, allowing sound to become noticeable elsewhere in the installation.

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 through the duct run.

It can be particularly effective when used immediately before or after an extraction fan, between a fan and carbon filter, or along duct runs where ventilation noise needs to be controlled.

Acoustic ducting is intended to reduce transmitted noise rather than make an extraction system completely silent. Fan type, speed, vibration, airflow velocity and installation quality will all influence the final sound level.

Ideal for 10-inch grow room ventilation systems

Larger grow rooms and indoor horticultural environments often require powerful ventilation to remove excess heat and humidity and maintain regular air exchange. As fan capacity increases, controlling ventilation noise becomes increasingly important.

The 254mm / 10" diameter makes this ducting suitable for compatible high-volume extraction and intake equipment, while its insulated construction helps reduce the sound transmitted through the ductwork.

It can be used as part of a complete ventilation system incorporating an inline fan, carbon filter, metal duct fittings, reducers and other appropriately sized components.

Getting the best airflow from flexible ducting

Good duct installation is important for maintaining the performance of an extraction fan. Every length of ducting, bend and fitting introduces some resistance to airflow.

Extend the duct sufficiently rather than leaving unnecessary sections heavily compressed. This provides a smoother internal airflow path and helps reduce avoidable resistance.

Keep the ventilation route as short and direct as practical and avoid crushing the duct or creating unnecessarily tight bends. Gradual changes in direction are preferable to sharp turns.

The supplied 5m length does not need to be used in full. Cutting it to the length actually required can help create a cleaner and more efficient installation.

Installing 254mm Mute Silent Ducting

Before installation, check that the fan, carbon filter and other fittings are compatible with the nominal 254mm / 10" duct size.

Fit the flexible inner duct securely around the ventilation connection and fasten it using a suitably sized duct clamp or fixing. HVAC foil tape can also be used where additional sealing is required.

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

Longer sections should be supported appropriately along the route. Avoid allowing the full weight of the ducting to hang directly from an extraction fan, carbon filter or other ventilation component.

Compatible ventilation equipment

254mm acoustic ducting can be incorporated into appropriately sized ventilation systems using components such as:

  • 254mm / 10" inline extraction fans
  • Compatible carbon filters
  • Ventilation silencers
  • Rigid round ducting
  • Metal duct connectors
  • Elbows and bends
  • Reducers and adapters
  • Duct clamps and fixing accessories

Always check the actual connection diameter of individual components before installation, as dimensions can vary slightly between different ventilation equipment manufacturers.

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 5 metre length.

Is this suitable for a 10-inch extraction fan?

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

Can I connect it to a 10-inch carbon filter?

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

Does acoustic ducting make a fan silent?

No. It helps reduce noise transmitted through the ductwork but cannot completely eliminate fan motor noise, vibration or airflow noise.

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 it be used for both extraction and intake?

Yes. The ducting can be incorporated into compatible extraction or fresh-air intake systems.

Can the 5m duct be cut into shorter sections?

Yes. It can be cut to suit the required installation, allowing one length to be divided into several sections if necessary.

Should I use the entire 5m length?

Only if required. Keeping duct runs reasonably short and direct generally helps reduce resistance and maintain ventilation performance.

Does long ducting reduce fan airflow?

Every duct run introduces resistance. Longer routes, tight bends and additional fittings can increase this resistance and reduce the effective airflow delivered by the system.

Do bends in flexible ducting affect airflow?

Yes. Sharp bends increase resistance, so gradual changes in direction are preferable wherever the installation allows.

Should acoustic ducting be stretched out?

It should be extended sufficiently for the installation rather than left heavily compressed, helping provide a smoother path for airflow.

Where should acoustic ducting be positioned?

It can be used throughout a compatible ventilation route. Sections close to powerful extraction fans can be particularly useful for reducing sound transmitted into the duct system.

Does 10-inch acoustic ducting need supporting?

Long runs should be adequately supported so the weight of the duct is not carried entirely by the fan, filter or connecting fittings.

How else can I make a grow room extraction system quieter?

Good duct routing, correctly sized ventilation equipment, vibration isolation, suitable fan-speed control and ventilation silencers can all help reduce overall system noise.
