Bag Filtration Systems

Our bag filtration systems are widely used for the reduction of sediment from industrial and food applications due to their high flow rate capability, easy maintenance, and rugged design. Siga Filtration can offer filter bags for general particulate removal and high-efficiency removal of particulates. For high flow rate applications, Siga Filtration can offer multi-bag filter housings that can handle flow rates of up to 400 m3/h. All standard filter bags are supplied with integrated handles for easy removal from filter housings. Filter bags are available with removal ratings from 0.5 – 1800 µm.

Specifications for Siga Filtration Filter Bags & Socks

Siga Filtration can supply filter socks in Polypropylene felt, Polyester felt, and Nylon mesh. Polypropylene felt has wide chemical compatibility and is suitable for most industrial, water and chemical applications up to an operating temperature of 80°C. Polyester felt filter socks have a high-temperature resistance (up to 120°C with SS or Polyester ring). These filter bags also provide excellent resistance against hydrocarbons and are a material of choice for the filtration and polishing of gasoline, diesel, biodiesel, and other fuels. Both Polyester and Polypropylene felt filter bags provide clarification of particles. These filter bags also provide removal of gelatinous or deformable particles due to the depth of the filter medium. Nylon monofilament mesh filter bags remove particles by sieving and are used for the classification of particles.
