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 micro-bubble level.
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. Micro-bubbles, fuse together,
increase in volume until they become large enough to rise to the top where
they are automatically released.
