TYPICAL SPECIFICATION
Furnish and install as shown on plans a horizontal in-line ai
r
separator designed to effectively separate free air in hydronic
heating/cooling systems. The air separator shall be heavy duty cast
iron designed to function satisfactorily at working pressures up to
175 psi (12.1 bar) and liquid temperatures up to 300 °F (149 °C).
The air separator shall have an integral weir designed to decelerate
system flow to maximize air separation.
NOTE:
Chose either A or B to complete this specification.
A
. For Use with Conventional Compression Tanks
(Excludes IAS-1 and IAS-1¼)
The in-line air separator shall also assist in eliminating free air in the
system by directing the air to a conventional compression tank while
reduced oxygenated water is circulated to the system. The ai
r
separator shall allow the expansion of the system fluid to be directed
to the compression tank.
B. For Use with Precharged Bladder and Diaphragm
Expansion Tanks
The in-line air separator shall also assist in eliminating free ai
r
from the system by directing the air to an air vent attached to
the separator while reduced oxygenated water is circulated to
the system. The in-line air separator shall allow expansion o
f
the system fluid to be directed to a precharged (Choose one:
BLADDER OR DIAPHRAGM:)_____________________

expansion tank.
The in-line Air Separator shall be ITT Bell & Gossett Model
No. _______ In-Line Air Separator.
