When you need to use silencers, you must ensure that they are the proper design. If your installation lacks something important or is the wrong size or shape, it won’t be able to minimise the noise effectively. Using our acoustic modelling software, we can create the right one for you. We will be able to offer you a discharge vent silencer that works as it should or any other model.
With silencer applications, you must choose the correct filter. To do so, you need to understand the available options. Trade-offs exist here between size, cost, durability, and efficiency. You have to think all of these through prior to picking the housing or filter-silencer.
What contaminants are you dealing with?
Filter selection needs to begin with you knowing the size of the contaminants you have to remove. The majority of filters are going to be rated based on the efficiency and size of those particles you can remove from the air.
One example would be choosing a filter for a regenerative blower. The majority of blower manufacturers recommend using filters possessing a 10-micron rating. However, with dusty food processing facilities that have flour dust in the air, a 10-micron filter may not suffice. It could fail to catch all the contaminants. In this scenario, the trade-off to consider is the cost of more recurring blower maintenance or more effective filters.
The filter materials
There are several kinds of materials in silencer filters. We will be giving a brief summary of three of them, starting with paper. These particular filters come with the best efficiency for filtering small particles. Because of the minimal cost, people tend to treat them as disposable once dirty. But, there are some variants you can clean using compressed air.
Secondly, there is felt. The majority of these filters use synthetic felt substances. For filtering out particles, they come with the second greatest efficiency. The advantage the material has over paper is that you can clean with water or compressed air. You can also use them several times.
Finally, there is wire-mesh. Typically made with galvanised wire, you can clean and reuse these filters indefinitely. But, this is the least effective filter material. To improve efficiency, you can treat them with adhesive. After each cleaning, you must reapply it. Ensure you keep the filters clean or their performance drops considerably.
