    The DISCAL® air separator 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. 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, fusing with each other, increase in volume (get larger) until they become large enough to rise to the top where they are automatically released.

    • Stainless steel float guide pin and linkage
    • Glass reinforced nylon internal element
    • 1/2 Inch NPT female bottom thread
    • Upto 100% removal air separation efficiency
    • Anti-rotation/anti-vibration pinned float creates space between float and air vent wall to prevent float hang-up from debris or variations in separator installation orientation
    • Anti-corrosion coalescing mesh constructed of glass-filled nylon, more resistant to dissolved oxygen and acidic fluids than plated metals
    • All components highly resistant to hydronic chemical additives or unstable pH fluid
    • Slows fluid flow dramatically, combines with concentric, sharp-edged mesh design to cause micro-bubbles to efficiently collect and coalesce
    • Reliable float alignment even during turbulent conditions such as filling from bottom

    Application: For closed hydronic systems
