Abstract
An arterial air eliminator includes an upper housing (10) and a lower housing (12). A first internal chamber (16) is formed adjacent the interior sides of the housing with an inlet tube (18) disposed in the upper end thereof. A purge outlet (20) is provided at the upper end of the air eliminator with a filter element (32) defining an interior chamber (24). Fluid flows into the inlet (18) and then through the filter (32) to an interior chamber (34) and out an outlet tube (36) on the lower end of the housing. The filter element (32) has a bubble point that is graduated from the top to the bottom such that the bubble point on the upper end is large relative to the bubble point on the lower end thereof. The microbubbles which exist in the fluid entering the inlet tube (18) are not passed through the upper end of the filter (32) and are purged to the outlet (20).
