Before you purchase fabric filter bags to collect dust and other substances, there are some factors that you need to keep in mind. The following are crucial tips for choosing the right fabric filter bag.
Understand the type of particulars that you are looking to filter before selecting a filter for your application. This will enable you to choose the right material of your filter bag that will tolerate the chemicals and the environment of your system to keep your plant and your workers safe. For instance, certain materials are highly flammable, therefore, you need to consider fibers such as epitropic felt, acrylic felt, polyester and polypropylene that support combustion.
The next step is to determine the right-sizing of your bag before you make a final filter bag selection. You can take the measurements including the length, width and diameter so as to know the right size of filter you will need. Similarly, you can contact your manufacturer who will assist you get a precise measurement of the filter.
You also need to consider the inlet temperature at the unit as it will play a crucial role in the selection of a fabric filter.

Filters that are not designed to withstand high temperatures risk being destroyed when exposed to high heat. For high temperatures filtration, you can use fabrics such as felt polyamide or aramid.
Chemistry with the gas stream is another key consideration when you are choosing fabric filter for your application. Consider if the chemical gas stream is highly active or acidic and consider a fabric that will be able to withstand these particles.

Also, Teflon is mostly used in carbon black plants, boilers and incinerators because it has low friction properties that make excellent cake discharge.
Think about the dangers of a static shock in your factory before you select your fabric filter bag. Determine which substances will be filtered and choose a filter bag that will be able to manage that risk. Also, filter bags that have polyester felt fabric or those equipped with copper or stainless steel ground wires are a good option since they ensure that static charge doesn’t reach ground levels.
Do some research on the manufacturing company and ensure that they adhere to strict standards during their manufacture of their products. The company should have experienced staff and qualified sales designers who will work to custom design the bags to meet your specific requirements.
