Abstract: A modular filter element frame (10) and a filter element frame assembly (100, 150) are disclosed. The filter element frame (10) has an elongate body (12) with a central bore (14) extending axially through the body. In cross-section the body has at least three smooth-ended lobes (16) that extend radially therefrom. The lobes are angularly spaced about the central bore such that a longitudinally extending channel (18) is formed along the body between adjacent lobes. Each channel has a plurality of longitudinally spaced apertures (20) extending into the central bore. Axially outer ends (24, 28) of the body are adapted to enable axial stacking thereof with like modular filter element frames to cooperatively form a filter element frame assembly (100, 150) with a required axial length. The assembly may receive a filter sleeve such that the sleeve extends at least partially along an outer periphery thereof.
