Things to Keep in Mind When Choosing a Baghouse Filter Bag

Fabric filter bags are used by different industries to capture dust particles which can be a health hazard, however, selecting the right bag that matches your specific needs can be difficult. Here is how to pick the best fabric filter bags.

Choose a fabric filter made of material which has a great chemistry with the gas stream in your system. If the environment is chemically active or acidic, you need to find a fabric filter bag that will withstand it. Teflon is an example of a fabric filter that has chemical resistance properties when it comes to dry and wet heat degradation. It is also used in boilers and carbon black plants due to its low friction properties which enable it to effectively release dust cake.

Before you purchase a fabric filter for your system, it is important to know the size of dust particles that you are looking to filter. Dust characteristic may vary from bulky, fine and coarse. There are also dust particles that are corrosive, hence, it is wise to choose filter bags that are constructed to support combustion and this may include; acrylic felt, epitropic felt, polyester and polypropylene.

When selecting your filter bags, you need to contemplate the temperature in the baghouse. If the temperatures in the baghouse system are very high, then you need to choose filter bags that are able to withstand it. When you choose the wrong bag to work in high temperatures environment, it is likely to get destroyed or melt in the process. Therefore, instead of using thermoplastic, consider fabrics such as felt polyamide and aramid.

It is recommendable to consider the moisture level to help you select the most appropriate bag for your filtration system needs. A good fabric that interacts well with various moisture conditions is polyester and this makes it utilized in baghouse systems for agriculture, and woodworking. It is also widely used because of it is effective in energy absorption and its resistance to mineral acids as well as most oxidizing agents and organic solvents.

Pick the right size of filter bag that will fit well in your unit’s dust collection system. A long filter bag may be effective in ensuring that you use few dust collectors and it will be able to cover a large filtering area. However, a filter bag that is too short will reduce the dust removal efficiency and many dust collector filter bags will be required.

It is also important to ensure that you get your supplies from a reputable company to ensure that they are high quality. When making your purchase, ensure that the seller provides you with a variety of fabric filter bags so you can choose the most suitable for your application.
