Noise silencers

Especially when growing at home, you will certainly appreciate every available means for discreet operation of a grow tent - growing exotic fruit and plants in a block of flats is really no joke. Fans can be perfectly silenced using noise silencers, which offer very versatile use and are suitable for almost all types of fans.

TIP: Use two silencers for one fan! Place one at the intake and the other at the outlet. And it will be quiet.

We offer two types of silencers:

• More mechanically resistant, but relatively heavy silencers with a metal casing
• Lower weight and a similar ability to dampen noise are shown by silencers with a plastic casing

However, no silencer on the market can completely silence the fan motor itself. But there is a solution, and it takes the form of quiet or silenced fans.

The classic choice is RUCK ISO-MAX or TD Silent fans with internal insulation. Boxed fans are also an option, for example Torin MDF Box with an insulating layer and huge capacity. A modern solution is PrimaKlima Whisperblower fans with a special design.

When silencing ventilation, ducting with an insulating layer, such as Combiflex or the premium PhonicTrap, will also help.

How do you choose the correct size of noise silencer?

The flange diameter is decisive - the silencer must match the connection diameter of your fan and ducting, commonly from 100 to 315 mm. The silencer is fitted directly onto the fan spigot, so you only need to know its size and choose the matching variant.

By how much will a silencer reduce ventilation noise?

The silencer mainly quietens the noise of air flowing through the ducting. You will get the most noticeable effect with a pair of silencers on the intake and outlet; however, it will not remove the noise of the motor itself - for that, you need a silenced fan.

Is a metal or plastic silencer better?

Metal versions, for example Can-Filters, are more durable and longer-lasting, but heavier. Plastic is lighter and easier to hang, with a comparable ability to dampen noise. The choice depends on whether you are more concerned about the load-bearing capacity of the structure or the weight of the assembly.

Where should the noise silencer be placed in the setup?

Ideally between the fan and the exhaust duct leading out of the tent, or also on the intake side. The closer the silencer is to the source of noise, the more effectively it captures turbulence before it resonates through the entire ducting.
