[AT] Air compressors?

[Gene Dotson]

    I will try to describe how I built them. My floppy drive on
my computer doesn't work, so can't send a picture of it.
    I started with a 3 foot piece of 1 1/4 inch copper pipe. On
the bottom I soldered a reducer coupling and threaded fitting to
accept a standard garden hose valve. At the top I soldered on a
reducer tee from 1 1/4" to 3/4 inch. This is the air outlet.
The top I made by inserting a piece of 3/4" copper pipe about 8
inches through the reducer coupling soldered it into place and
then soldered a 90 degree ell and then a hose barb to hook to
the compressor with a 1/2 inch hose.  Then with a short nipple,
I soldered this to the top of the unit. You will probably have
to remove the locating ridge inside the reducer to get the pipe
to slide through the reducer.
    The unit is mounted vertically with the inlet coming in the
top and the outlet coming out the side. The inlet pipe extending
below the outlet pipe forces the water to fall to the bottom and
with the reduced velocity of the rising air, allows the water to
stay at the bottom of the trap.
    My air compressor is set to shut off at 150 PSI and I use a
pressure regulator and run 110 PSI in the shop lines.
    I am sure you are aware that for soldering, absolute
cleanliness of all soldered joints is a must. Even new fittings
must be sanded to bright bare copper before soldering. A good
flux on all joints is also very important. I used lead free
solid core solder with good results.
    I hope you are able to follow my thinking on this.

                        Gene

: Tell us a little about the construction of these separators,
Gene.  How are
: the inlet and outlet arranged so as to encourage condensation
without
: blowing the water on through.

:     Ralph;
:     I have solved my water problem by mounting 2 water
seperators together
: in series and mounting them on an old disc blade. They are the
larger 3/4'
: ones. I have a double quick disconnect outlet on it and a male
quick
: disconnect on the input side. When I am sandblasting, I leave
the drain
: valve cracked on the first stage seperator to let out most of
the water. The
: second stage seldom collects any water.
:     This setup is handy and portable. It is very useful when
using air tools
: and will increase the life of the tools considerably.
:     I have a 6 horsepower heavy duty compressor that is hard
piped in my
: shop with copper tubing. I have 6 air connectors in my shop
and 2 outside
: the shop. I have 2 homemade seperators that I made from 3 foot
pieces of 1
: 1/4 inch copper pipe with a drain valve in the bottom. One is
right after
: the compressor and the other is at the far end of the shop.
All of the air
: is run the length of the shop to assure it has cooled enough
for the water
: to settle to the bottom so it can be drained. After the second
seperator, I
: run the lines for the shop air. When I use the portable
seperators, I am
: actually seperating the water at 4 stages of seperation, not
counting the
: water that collects in the compressor tank.
:     My bead blast cabinet is hooked directly to the shop air
lines with 1
: water seperator and I very seldom collect enough water to have
to drain this
: seperator.
:     I have been very pleased with this system and have never
regretted the
: time and expense to install it.

: : Thanks for the idea Richard. I will have to try and rig up
something like
: : that on the outlet valve of my big compressor. This freezing
air nozzle
: : problem is getting really annoying. Even had problems
putting air into a
: : tire the other day. Maybe the humidity is higher here now
than we are used
: : to.
