Inline Metal Duct Silencer 4″*12″

  • Easy to install
  • Lightweight
  • Reduces noise through ventilation system by up to 50%
  • Keeps your grow room whisper quiet
  • Acoustically insulated

In an urban environment, where indoor hydroponic farming is becoming more and more prevalent, noise pollution can quickly become a problem, causing many disputes amongst the immediate neighbours. Grow room silencers are the perfect way to reduce the noise of from a hydroponic extraction system you have installed in your grow room.

They are lightweight and easy to set up. The aluminium housing is tough and durable enough for any grow room and the foam insulation provides the acoustic buffering to reduce the decibel levels by up to 50% in some cases.

Silencers are applied for noise absorption during the operation of the fan spread along the ducting systems. Suitable for installation into round ducts. The silencer will reduces the noise level in the air duct.
The SIL consists of a polypropylene inner duct, thermally and acoustically insulated with a glass wool layer and provided with an aluminium laminate outer jacket. Both ends are taped to create ready-made connections.
NEN 13180 Fulfils all the requirements and are classified as specified within NEN 13180: “Ventilation for buildings – Ductwork – Dimensions and mechanical requirements for flexible ducts”


You will want to attach your silencer just after the fan in the extract duct run, to soak up any noise generated by the motor. Ideally it will be connected with a fast clamp to ensure a nicely sealed, air tight connection. Then simply connect your ducting as your normal and run it to the usual place.

Bear in mind that the acoustic foam will slightly reduce the air flow rates throughout your system. It will not be by much, but there will be a small drop in the overall airflow rates.

Also worth considering if noise is a concern is to make sure that your ducting is pulled as straight and as tightly as possible. Not only will this reduce any extra noise generated from turbulence in the ducting, it will also help to improve the overall air flow rates.
