Enhanced Air Separator
AIR SEPARATORS EASB-Jr Enhanced Air Separator
Description
Bell & Gossett’s Model EAS Enhanced Air
Separator is a patented, innovative design in air
separators. It has been engineered to remove
entrained air from hydronic heating and cooling
systems providing far superior air removal
compared with other devices available today.
The EAS is ideal for residential, institutional
and light commercial applications.

Description
Bell & Gossett’s Model EASB-
JR Enhanced Air Separator
automatically removes entrained
air bubbles in hydronic systems. As
fluid enters the EASB-JR, the velocity
is decreased creating a low pressure
area. The small bubbles are released
from fluid and then collected on the
coalescing medium. As the bubbles
coalesce, they rise to the top of the
air separator where they are released
to atmosphere through the built-in
automatic air vent. The air separator
has a bottom 1/2” NPT connection
to accommodate a B&G diaphragm
expansion tank. The compact design
and brass body construction make
the EASB-JR ideal for residential
and commercial hydronic heating
systems.
How It Works
1
As system fluid enters
through the inlet, (either
straight or angle) the diffuser
distributes flow evenly across
the stainless steel, wire
brush-like medium.
2 Air bubbles, even micro air
bubbles, stick to the brush
filaments.
3 Trapped air rises above the
diffuser through a baffle (not
pictured), where the air is
then released through
an opening on top.
4 Deaerated water then goes
back into the system.
