Blowdown Separators for Boilers
To select the proper blowdown separator for your application,
you need to know both the boiler operating pressure and the
size of the bottom blowdown connection. Using those two figures,
you can match the bottom blowdown inlet on the blowdown separator
to the boiler blowdown connection size from the table in the
above dimensional
and installation drawing PDF File.

For example, the proper
blowdown separator connection for a 125 psi. boiler with
a 1-1/2" bottom blowdown connection, you'll need part
number BD230D45. The aftercooler size is determined by the
size of the drain in the blowdown separator. The temperature
regulating valve sizing is dependent on the cold water inlet
on the aftercooler selected. For sizing on blowdown tanks,
or for blowdown separators for boilers over 300 psi, contact
the factory. All connections 2-2/1" and smaller are NPT,
3" and larger are 150
psi RF flanged.
