SilencedAir Silencers
SilencedAir Silencers
Reduce unwanted ventilation noise with SilencedAir Silencers. Designed to be fitted into ducting systems, these silencers help absorb sound generated by extraction fans and moving air, creating a noticeably quieter ventilation setup.
Ventilation systems can produce noise in several ways. As well as the sound of the extraction fan itself, moving air can create additional noise as it travels through ducting, bends and other components. A SilencedAir Silencer is designed to reduce the amount of this sound that travels along the ductwork.
Available in a range of popular duct diameters and three different lengths, SilencedAir Silencers can be matched to a wide variety of extraction and ventilation systems.
How Does a Duct Silencer Work?
A duct silencer is installed directly into the ventilation system, usually alongside the extraction fan and ducting. As air passes through the silencer, its internal construction helps absorb sound energy while still allowing air to travel through the ventilation system.
This can help reduce both fan noise and airborne noise travelling through the ductwork. It is particularly useful with powerful extraction systems where fan and airflow noise can become more noticeable.
For best results, the silencer should be correctly matched to the diameter of the ducting and extraction fan being used.
Why Use a Silencer?
Extraction is essential for maintaining good airflow and environmental control, but a powerful ventilation system can also be one of the loudest parts of an indoor growing setup.
Adding a SilencedAir Silencer can help reduce unwanted sound without having to completely change your existing extraction system. This makes them particularly useful for grow rooms, grow tents and other indoor gardening spaces where keeping noise levels under control is important.
- Helps reduce unwanted extraction fan noise
- Reduces sound travelling through ventilation ducting
- Helps absorb noise generated by fast-moving air
- Suitable for use with a wide range of extraction systems
- Available in popular duct diameters
- Available in three different lengths
- Can be used individually or in series for additional noise reduction
Choosing the Right Length
SilencedAir Silencers are available in three different lengths, allowing you to choose a model to suit your available space and the level of sound reduction required.
As a general rule, the longer the silencer, the greater its potential to reduce noise. A longer silencer provides a greater area for sound absorption and is therefore the preferred choice where maximum noise reduction is the priority.
Shorter models are useful where installation space is limited or where only moderate noise reduction is required.
Using Two Silencers in Series
Where unwanted ventilation noise is a particular problem, two SilencedAir Silencers can be installed in series. This means fitting two silencers within the same duct run to provide additional sound attenuation.
This can be useful with larger or more powerful extraction fans, or in installations where keeping ventilation noise as low as possible is particularly important.
Where Should I Install the Silencer?
The silencer forms part of the duct run and should be connected to appropriately sized ducting. The exact position will depend on the layout of your ventilation system and the main source of unwanted noise.
Keeping duct runs as smooth and straightforward as possible can also help with overall ventilation performance. Excessive bends, restrictions and poorly fitted ducting can increase turbulence and contribute to additional airflow noise.
Match the Silencer to Your Ducting
Always choose a SilencedAir Silencer with a diameter that matches the rest of your ventilation system. Correctly matching your fan, silencer and ducting makes installation easier and avoids unnecessary changes in duct diameter.
SilencedAir Silencers are available in a selection of popular sizes, making it easy to incorporate one into both new and existing ventilation setups.
Ideal for Indoor Growing Environments
SilencedAir Silencers are a simple addition to grow room and grow tent ventilation systems where unwanted extraction noise needs to be kept under control.
They can be used alongside extraction fans, carbon filters, ducting and other ventilation equipment to help create a quieter environment while maintaining the airflow required by your plants.

SilencedAir Silencer Sound Attenuation
The amount of sound attenuation varies depending on the SilencedAir model and the frequency of the sound. The table below shows the attenuation performance in decibels (dB) across frequencies from 63 Hz to 8000 Hz.
Attenuation [dB] for frequency [Hz]:
| Frequency in Hz | Attenuation [dB] | |||||||
|---|---|---|---|---|---|---|---|---|
| 63 | 125 | 250 | 500 | 1000 | 2000 | 4000 | 8000 | |
| 150mm (6 inch) -600mm | 8,3 | 10,8 | 14,5 | 24,9 | 36,2 | 35,0 | 21,1 | 20,8 |
| 200mm (8 inch) -600mm | 7,5 | 9,6 | 12,4 | 21,6 | 32,2 | 29,0 | 18,2 | 18,1 |
| 250mm (10 inch) -900mm | 8,1 | 8,9 | 14,1 | 26,9 | 38,2 | 30,7 | 20,2 | 19,6 |
| 250mm (10 inch) -600mm | 7,0 | 8,8 | 10,9 | 19,1 | 29,1 | 24,4 | 16,0 | 16,1 |
| 315mm (12 inch) -900mm | 7,5 | 7,9 | 12,5 | 24,2 | 35,0 | 25,9 | 17,9 | 17,5 |
| 315mm (12 inch) -600mm | 6,4 | 7,8 | 9,3 | 16,4 | 25,9 | 19,6 | 13,7 | 14,0 |
| 355mm (14 inch)- 600mm | 6,1 | 7,4 | 8,4 | 15,1 | 24,2 | 17,1 | 12,5 | 12,9 |
