Knight Filter Bag Baskets and Strainers
Knight manufactures replacement bag filter baskets and basket strainers for a wide range of filter housings and offers replacements for all current models, and any that have been discontinued by the original manufacturer.

Knight Corporation offers a wide selection of baskets to fit all make filter vessels currently being used in the industry. Our baskets strain and filter a variety of fluids to trap solids of almost any size. All baskets can be easily removed for cleaning and are made in lengths to fit your specific vessel size. All of our baskets are precision crafted and are available in high quality stainless steel or carbon steel. There are two basic basket styles from which to choose: strainer basket or bag basket – with or without mesh liner. The correct style basket is determined by your specific straining or filtering requirement. The strainer basket will remove particles down to 74 microns and the filter bag will remove particulates down to 1 micron.
