Abstract
Esp. for use in automobiles and air compressors, the element has a central core and a coaxial outer case, between which are wound two coaxial, spiral bands of filter material held apart to form two separate, adjacent spiral channels. One channel is sealed off at one axial end of the element and the other channel is sealed off at the other end so that fluid entering at one end has to change channels through the filter material to leave at the other end. The element has a high capacity for a given size.
