Installation, Operation and Service Instructions
Enhanced Air
Separator
Model EAS
DESCRIPTION
The Bell & Gossett Model EAS Enhanced Air Separator is a
highly efficient device for removing entrained air bubbles in
hydronic systems. The combination diffuser and coalescing
medium design makes possible the removal of very small air
bubbles from the fluid stream by coalescence at substantial
fluid velocity. The diffuser forces the system fluid to cover the
entire inlet portion of the coalescing medium. The coalescing
medium will collect air bubbles on its stainless steel filaments.
As the bubbles coalesce together, they will rise to the top of
the separator where they can be released to the atmosphere
through the automatic air vent.
