Have no idea what you talking about but if you check with
drier OEMs you find out that filters are made for liquid filtering
and not for gas, in gas line are ineficient and that is why are
never install in gas lines, however you can install them any
place you wish, filters are also made for suction lines oil return
lines but not for gas lines in refrigeration systems.

One time, the parts house suggested a vapor line filter. it was rather
short, and a very wide cross section. Looked like the filter had swollowed a
pizza pie.

Unlike the liquid line filters which look like a snake which has swollowed a
wooden barrel.

Generally, after a compressor replacement, it is recommend that a suction
line filter drier be installed. If it's a burn out, a high in carbon filter
drier is used to help remove acidic particulate.

For the Old & Grumpy, the suction line contains vapor. It is highly NOT
recommended to put any desiccant drier in the hot gas discharge line. Only
in the liquid or suction lines.

Because of limited use of "flushing agents", most Manufacturer's don't
recommend putting anything in a refrigeration system other than refrigerant
and refrigeration oil. After 1990, the use of R-11 as a flushing agent was
banned, [although a good remedy for cleaning and flushing burnt material
from a burn out.]

Because of the metering devices, four way valves, and check valve [in some
systems] desiccant driers are high recommended. Sometimes some
Manufacture's recommend new four way valves as well for burn outs.

Good Luck Mr. O.P.

        Not true. In fact, many units come stock with exactly that.
And no, I don't mean the mufflers.

        Sporlan and Alco both approve them for discharge use.

Really Paul;

I've seen several jobs where Sporlan driers were installed incorrectly in
the hot gas discharge [because the person perported to 'know'] and, the
result was a dissintigration of the drier's contents. Funny how while the
unit was running, you could hear the material racing around the condenser.

Show me where Parker / Sporlan manufacturers' a drier for use in the hot gas
discharge line of a refrigeration system.
