Description
A quick and easy “in-line” replacement for other types of side inlet/side outlet
traps, the Armstrong 1800 Series brings together all the benefits of energyefficient inverted bucket operation. Side inlet/outlet all-welded construction
means an inverted bucket trap that will operate efficiently on applications
such as tracer lines, drips, heating, processing and similar applications.
With the 1800 Series you get freeze-resistant, all-stainless steel construction,
with a three-year guarantee, plus all the benefits of inverted bucket operation:
Long, trouble-free service life
• Excellent purging action
• Continuous air venting
• Ease and flexibility of in-line installation

*NOTE: Because the orifice is located at the top, inverted bucket steam traps
handle dirt and scale better than other types of traps. However, in applications
where extremely dirty conditions exist, care should be exercised in the use of
all types of restricted-orifice, reduced-capacity traps.
Pop Drain for Freeze Protection
In general, a properly selected and
installed Armstrong trap will not freeze
as long as steam is coming to the trap.
If the steam supply is shut off, a pop
drain should be used to automatically
drain the trap. Stainless steel pop drain
available for Models 1811 and 1822.

Insu-Pak™
Now you can insulate the in-line traps in
your plant without complicating regular
trap maintenance. Insu-Pak, a simple
reusable insulation package, cuts the time
and cost of in-field installation because
it goes on in a snap. And it comes off
just as easily. Insu-Pak can prevent trap
freeze-up when used with a properly
designed condensate manifold. Designed
for use with Model 1810 and Model 1811
traps.
Probe connections are available for
trap monitoring on Models 1811 and 1822.
