Contactor supporting tubes (19) are secured to an end frame (42) of a rotor by drawing each tube tightly up to an end frame by means of a bolt (44) which extends through the end frame member into a tapped plug (36) in the end of the tube. Where each tube (19) passes through an aperture in the contactor element, a reinforcing skirt (46) bounds the aperture.
