Filter Bag Support Basket in 316L Stainless Steel (AISI 316L (1.4404)) is used for supporting liquid filter bags inside bag filter housings with perforated stainless baskets that keep the bag from bursting under pressure. The alloy gives superior resistance, including chlorides, brines, food CIP and mild acids and is essentially non-magnetic, with a practical service limit of approx. +550 °C continuous.
