Abstract
A filter assembly includes a filter vessel having an inlet, an outlet, and defining a filter chamber therebetween. A basket assembly is removably supported within said filter chamber and has a diameter less than the diameter of the filter chamber so as to define an annular flow path about the basket assembly. The basket assembly includes an outer, permeable member and an inner, permeable member having a diameter which is less than the diameter of the outer, permeable member such that the inner, permeable member is received with in the outer, permeable member so as to define an annular space therebetween and an inner flow path. The basket assembly supports a bag-type filter over both the inner and outer permeable members bounding the annular space therebetween. The bag-type filter includes a first portion having a first, larger diameter and a second portion having a second, reduced diameter. A transition portion is disposed between the first and second portions of the bag-type filter.
