Caleffi 551009AC 551 Series Discal Air Separators with Expansion Tank Check 2" NPT Female

Air separators are 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 the micro bubble level. The circulation of fully de aerated water enables the equipment to operate under optimum conditions free from noise corrosion localized or mechanical damage. Micro bubbles fusing with each other increase in volume get larger until they become large enough to rise to the top where they are automatically released.
