102mm (4") 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 is essential for controlling temperature, humidity and air quality, but conventional flexible ducting can transmit noise generated by extraction fans and fast-moving air. This insulated ducting provides a practical solution for installations where quieter ventilation is required.

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

Supplied as a generous 10 metre length, this 102mm version can be used as a continuous duct run or cut into shorter sections to suit the ventilation layout. It is designed for use with compatible 4-inch extraction fans, carbon filters and ventilation fittings.

Why choose 102mm acoustic silent ducting?

  • Helps reduce ventilation noise - acoustic insulation helps absorb sound transmitted through the ductwork.
  • 102mm / 4" nominal diameter - suitable for compatible 4-inch ventilation systems.
  • 10 metre length - ideal for longer duct runs or cutting into multiple 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 compatible inline fans, carbon filters and ventilation fittings.
  • Suitable for intake systems - can also be incorporated into appropriately designed fresh-air intake routes.
  • Ideal for indoor horticulture - particularly useful in grow tents, grow rooms and propagation environments.
  • Cut to suit the installation - use only the length required and retain the remainder for additional ventilation runs.

How does acoustic ducting help reduce noise?

An extraction system can produce noise from the fan motor, vibration and the movement of air through filters, ducting and fittings. Some of this sound can travel along ordinary ductwork and become noticeable at the intake or exhaust end of the system.

Acoustic ducting surrounds the flexible inner air passage with insulation. This layer helps absorb sound transmitted through the duct rather than allowing it to travel as freely along the ventilation route.

It can be particularly useful on duct runs immediately before or after an extraction fan, between compatible ventilation components and along exhaust routes where reducing transmitted ventilation noise is desirable.

Acoustic ducting is designed to reduce transmitted noise rather than make a ventilation system completely silent. Fan design, airflow velocity, vibration, duct routing and the overall extraction system will all affect the final noise level.

Quieter grow room and grow tent ventilation

In an indoor growing environment, extraction systems may run for long periods to manage heat and humidity and maintain a regular exchange of air. This can make ventilation noise one of the most noticeable parts of the environmental control system.

Acoustic ducting is a straightforward way of addressing noise transmitted through the ductwork without changing the basic operation of the extraction system.

The 102mm / 4" diameter is particularly suited to compatible smaller ventilation installations, while the 10m length provides additional flexibility for longer routes or installations requiring several individual sections of duct.

Getting the best airflow from flexible ducting

Correct installation is important because every length of ducting and every bend adds resistance to the ventilation system. The more resistance the fan has to overcome, the lower its effective airflow can become.

Extend flexible ducting sufficiently for the required route rather than leaving large sections heavily compressed. This reduces unnecessary internal corrugation and creates a smoother path for moving air.

Keep the route as direct as practical and avoid crushing the duct or introducing unnecessary tight bends. Where a major change in direction is required, a smooth bend generally provides a better airflow path than sharply folding the flexible duct.

A 10m roll does not need to be used in its entirety. If the installation only requires a shorter route, cutting the duct to the appropriate length can help avoid unnecessary resistance.

Installing 102mm Mute Silent Ducting

Plan the ventilation route before installation and determine how much ducting is actually required. The 10m roll can then be cut into the appropriate lengths for the system.

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

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

Longer sections should be adequately supported. Avoid allowing the full weight of a long insulated duct run to hang directly from the extraction fan, carbon filter or another ventilation component.

Compatible 102mm / 4" ventilation equipment

This ducting can be incorporated into appropriately sized ventilation systems using components such as:

  • 102mm / 4" inline extraction fans
  • 102mm / 4" carbon filters
  • 102mm / 4" ventilation silencers
  • Compatible rigid round ducting
  • 102mm / 4" elbows and bends
  • 102mm / 4" 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 commonly used together, but exact connection dimensions can vary slightly between products.

102mm (4") 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 ductwork.

What size is this ducting?

This version has a nominal diameter of 102mm, approximately 4 inches, and is supplied in a 10m length.

Is it suitable for a 4-inch extraction fan?

Yes, provided the extraction fan has a compatible nominal 102mm / 4" duct connection.

Can I use this with a 4-inch carbon filter?

Yes. It can be connected to compatible 102mm / 4" carbon filters as part of an appropriately designed extraction system.

Is acoustic ducting suitable for grow tents?

Yes. It is particularly useful where reducing the amount of ventilation noise transmitted through grow tent ducting is important.

Will it make my extraction fan silent?

No. Acoustic ducting helps reduce sound transmitted through the ductwork, but it cannot eliminate fan motor noise, vibration or all airflow noise.

Is acoustic ducting quieter than standard flexible ducting?

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

Can I cut the 10m roll into shorter lengths?

Yes. The duct can be cut to suit the individual ventilation layout, making a 10m roll useful for either a longer route or several shorter sections.

Can this ducting be used for intake air?

Yes. It can be used in compatible air-intake installations as well as extraction systems.

Can it be used with a ventilation silencer?

Yes. Acoustic ducting can be combined with a compatible silencer where additional control of transmitted ventilation noise is required.

Does flexible ducting affect airflow?

All ductwork creates some airflow resistance. Excessive length, tight bends and heavily compressed flexible ducting can increase that resistance, so a direct and properly extended installation is preferable.

Should I use the full 10 metres?

Only if the installation requires it. Using the shortest practical duct route generally helps minimise airflow resistance.

Can the ducting be bent around obstacles?

Yes. The flexible construction allows it to be routed around equipment, although sharp bends and crushed sections should be avoided.

How should the ducting be attached to ventilation equipment?

The inner duct should be secured to the compatible connection using an appropriately sized duct clamp or clip. Suitable HVAC foil tape can be used where additional sealing is required.

How else can I reduce extraction-system noise?

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