How to select Duct Silencers

A duct silencer is one of the most useful devices that you could ever install in your ventilation system. Not only will it ensure the adequate sound of all working applications, it will provide efficient operation for many years to come.

The first step in selecting a perfect duct silencer is to determine the noise level and the amount of noise reduction you might need. The noise is reduced from the system by adding resistance to the airflow. The maximum amount of resistance is also a factor that you should specify before buying the device. If your system can’t handle new airflow it will fail and you will need to spend hundreds of dollars on to repair it. The value of the total CFM will help you make the right decision. Maximum static pressure drop is other important factor that requires your attention. This is the resistance value that we were talking about earlier.

To install a duct silencer into the existent ventilation system you need to know the dimensions of duct work and fan outputs. Since a silencer usually connects to a fan application, it is important to ensure that both of them have all of the necessary mounting fittings and accessories. It’s also important not to forget about the maximum length of the silencer and for it not to exceed the allowable level. Remember that restrictions are made for your own safety.

The material of a duct silencer doesn’t play an important role in its correct operation. Most modern compact silencers are made from galvanized steel and this is not a coincidence. First of all, such material perfectly fits all flexible ducting and provides long lasting and reliable connections. Secondly, when used in duct silencers, galvanized steel reduces sound level and helps you increase the comfort in your house by eliminating all of the unnecessary sounds from the ventilation system.

Knowing all of the characteristics that are listed above will help you find a perfect duct silencer in no time. Even still, it is likely that you will still have some questions and for this reason we have included answers to the most frequently asked questions.

How will I know that the duct silencer is compatible with my system?

To know this you need to measure the diameter of the flexible duct and the fan that will be connected to the silencer and compare them. If they match, there is nothing to worry about.

How much does a duct silencer cost?

It all depends on the type and brand of such device. There are numerous manufacturers that offer high quality items with affordable pricing and warranty. You should definitely look for such duct silencers rather than selecting the option with the lowest price.
