Abstract
A coalescing filter element for removing liquid droplets from a gas stream comprises a wall which is made of a coalescing filtration material and which defines a hollow space within it. An end cap at one end of the element has a port in it through which gas is supplied to the hollow space to flow through the wall of the filtration material. The end cap has a peripheral portion which engages the element wall and a tube which extends into the hollow space defined by the element wall, so that the port in the end cap comprises an inner opening defined by the tube and at least one peripheral opening located between the tube and the peripheral portion of the end cap. The tube extends beyond the peripheral opening(s) so as to deliver gas to a region of the element wall which is remote from the end cap.
