AIR SEPARATORS
Construction details
The air separator uses the combined action of several physical principles.
The active part consists of an assembly of concentric mesh surfaces. These
elements create the whirling movement required to facilitate the release
of microbubbles and their adhesion to these surfaces. The bubbles, fusing
with each other, increase in size until the hydrostatic thrust overcomes the
adhesion force to the mesh. They rise towards the top of the unit from which
they are released through a float-operated automatic air vent with stainless
steel float guide pin, which keeps the float from binding.
