Fabric filter bags are widely used in most industries to remove impurities and dust particles that may affect the performance of the company. The following are crucial tips for choosing the right fabric filter bag.
First of all, know what you are filtering before you begin your purchase for a filter bag. 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.
Filter bags come in various sizes, hence, you need to know the exact specification that will work with your system. You can take the measurements including the length, width and diameter so as to know the right size of filter you will need. If you are uncertain about the right filter size for your application, be sure to contact your manufacturer for guidance.
Temperature is another thing that you should consider when choosing your filter bag. Your choice of filter bag should mainly be determined by whether it is able to withstand the temperature in your work environment. This is crucial because filters made of thermoplastic can be destroyed when they are exposed to very high heat. When selecting filters to be sued at high temperatures, it is advisable to use fabrics like felt polyamide or aramid.
Chemistry with the gas stream is another key consideration when you are choosing fabric filter for your application. If your system has very high chemical gas stream, you need to select a fabric filter that will withstand the chemically active particles. A perfect fit for such environment is Teflon whose fibers are chemical resistant to heat degradation. Besides, due to its low friction properties, it provides good cake discharge and it can be used in boilers, incinerators and carbon black plants.
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.
It is also crucial to ensure that you purchase your filter bags from a reputable company ensures high quality. A good company will have an experienced team of designers to custom make the bags according to your requirements and advise you on the best selection of your application.
