A filter bag is a component used in filtration systems to retain solid particles present in a gas or liquid flow. It is a cylinder of porous filter material, usually woven from synthetic fibers such as polyester (PES), polyamide (PA), polytetrafluoroethylene (PTFE), polyacrylonitrile (PAN), polyphenylene sulfide (PPS), meta-aramid, and fiberglass.
Filter bags are used in a wide variety of industrial applications, such as water treatment plants, ventilation systems, manufacturing processes, and environmental pollution control. Their design and characteristics can vary depending on the specific needs of each application, including pore size, chemical and thermal resistance, and filtration efficiency.
At Finsa JOB | Group, we are specialists in offering high-quality filtration solutions tailored to the specific needs of our customers. To ensure optimal performance and a long service life of our filter bags, we use a wide range of fibres and apply various types of finishes. These are carefully designed to improve filtration efficiency and adapt to the process conditions and granulometry of the product to be filtered.
Our bags can also be manufactured using microfibres that provide greater resistance to the material, antistatic fibres, water-repellent chemical treatments and lamination of microporous PTFE membranes, among others. In addition, we can make the bags with different types of finishes that include:
In addition to a wide range of finishes, our filter bags are custom made in any length or diameter that the customer requires.
At Finsa JOB | Group, we are committed to offering the highest quality filtration products to meet the needs of our customers. Therefore, we subject each stage of the process, from the selection of raw materials to the final manufacture of the bags, to strict quality controls.
Our experts closely monitor each step of manufacturing to ensure compliance with the highest quality standards. In addition, we carry out tests and evaluations at different stages of the process to verify the strength, durability and efficiency of the filter bags.
