Bag Filters

  • Bag filters are designed for high-volume liquid treatment and coarse particle removal, utilizing filter bags made from polypropylene, polyester, nylon, and other materials. With a simple structure and high dirt-holding capacity, they provide cost-effective performance in pre-filtration processes. They are available in a wide range of options, from general industrial bags to multi-layer precision types, and are compatible with various housing sizes depending on flow conditions. Common applications include paint, petrochemicals, water treatment, metalworking, and food & beverage industries, where removal of high-concentration contaminants is required.

How Do Bag Filters Operate?

  • Bag filters operate using a pouch-shaped filter bag that captures impurities as liquid passes through. Contaminants are retained on the inner surface and within the volume of the bag, offering a simple yet cost-effective solution with high dirt-holding capacity. Even in processes with heavy contaminant loads, clogging is delayed, resulting in longer service cycles.
  • Available in a variety of materials and micron ratings, bag filters are applied across industries such as chemicals, coatings, water treatment, and food & beverage. They are particularly effective for removing relatively larger particles and are commonly used in high-flow processes as a pre-filtration step. Their easy replacement and low maintenance further improve operational efficiency and help reduce total cost of ownership (TCO).
