Airtrol Tank Fittings
Air Control
TANK FITTINGS DESCRIPTION
A
irtrol Tank Fittings help establish the proper initial liquid
level in the compression tank when filling the hydronic
system. They help maintain proper system pressurization
by directing released air to the compression tank during
system operation and permit cooler liquid flow to the
boiler during the off cycle as system liquid cools. Airtrol
Tank Fittings must be used with the appropriately sized
In-Line Airtrol or Rolairtrol air separator.
