Caleffi Discal Air Separator 3/4 inch NPT Female - 551005A is used to continuously remove the air contained in the hydronic circuits of heating and cooling systems. The air discharge capacity of these devices is very high. They are capable of removing automatically all the air present in the system down to micro-bubble level. In PEX Radiant Heat Systems you need an air removal systems that pulls out micro bubbles as this is what is created in Radiant Heating Applications.

The Caleffi 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 bouyancy force overcomes the adhesion force to the surface. They rise to the top of the unit from where they are released through a fl oat-operated automatic air release valve

The circulation of fully de-aerated water enables the equipment to operate under optimum conditions, free from any noise, corrosion, localized overheating or mechanical damage.
