Abstract

A filter insert includes a plurality of annularly-shaped, bag-type filter sleeves (111, 112, 113) concentrically-arranged. The ends of the sleeves are attached to the flanges of an inlet plate 114, an annular terminal plate 124 or a circular terminal plate 121 (e.g. by ultrasonic welding). The filter insert is removably placed within a basket such that concentrically-arranged screens (160, 161, 163) of the basket support respective filter sleeves against radial flow during filtration.
