Abstract
A filter element for removing material that is entrained in a gas stream comprises a wall of a filtration medium which defines a hollow space, for a gas stream to flow from the space through the wall. The filter element includes an end cap having an inlet tube for a gas stream to be supplied to the space. The tube has at least one helically extending rifle formation in its internal wall by which a helical flow is imparted to the gas stream when it leaves the tube.
