The DISCAL® air separator uses a coalescing element that consists of an element of concentric diamond pattern mesh surfaces. This element creates the whirling movement required to facilitate the release of micro-bubbles and their adhesion to these surfaces. The bubbles, fusing with each other, increase in volume until the buoyancy force overcomes the adhesion force to the surface. They rise to the top of the unit from where they are released through a float-operated automatic air release valve.
