Caleffi 1-1/4" Sweat 546 Series DISCALDIRT Air & Dirt Separator

The DISCALDIRT air and dirt separator uses a coalescing element that consists of an assembly 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 bouyancy force overcomes the adhesion force to the surface. They rise towards the top of the unit and are released through a float-operated automatic air release valve. The dirt separating action performed by the same element which offers little resistance to the medium flow while ensuring dirt separation. The particles collide with the concentric diamond pattern mesh surfaces and then settle to the bottom, and not by filtration unlike mesh strainers; which, over time, get progressively clogged. By contrast, the DISCALDIRT’s low-velocityzone dirt separator function efficiently removes the particles to as small as 0.2 mil with very low head loss. The dirt can then be removed t...
