PRELIMINARY
Moisture is always present in compressed
air. Oil is almost always present at some
points in a compressed air system.
Moisture and oil must be removed from
the system for efficient operation and
long life of gaskets, hoses, and air tools.
Efficient moisture and oil removal that
will forestall trouble requires:
Aftercoolers to bring the compressed
air down to ambient or room
temperature.
Separators to knock down suspend-
ed droplets of water or fog.
Separators are installed downstream
from aftercoolers or in an air line
near point of use, or both. Note - air
traps are not separators.
Air Traps to discharge the liquid
from the system with a minimum
loss of air.

* C a p a c i t y - Mere water handling capacity is not the whole story. The No.813 is the smallest inverted bucket air trop with
sufficient power to give dependable service when heavy oil is present with the water. Do not use smaller traps if heavy oil
is present in your air system.

Installation, Operation & Maintenance Data
directed by the equipment manufac-
turer. Traps should be accessible to
the maintenance man. If lack of
headroom prevents trap installation
below a receiver, install as shown in
Fig. 2. If trap must be installed
above the dram connection, an inter-
nal check valve or swing check is us-
ed to prevent trap prime loss when
air pressure drops.
2.
First install piping and shut-off
valve ahead of trap, then blow down
the line at full pressure to remove

pipe cuttings, scale, and dirt. Last of
all, screw the trap into position.
4.
Caution - since the trap operates
with the body full of water, do not in-
stall where freezing can occur unless
proper non-freeze precautions are
taken.
TRAP INSPECTION
AND MAINTENANCE
Check trap operation periodically.
1.
Determine that body is full of water
(trap is primed).
2.
If examination shows heavy coating
on mechanism, arrange to clean
of oil
at regular intervals. Clean body and
cap as well as mechanism.
3.
Examine mechanism at least once a
year to determine tightness of valve
and seat and if any parts require
replacement.
If repairs are
necessary, contact your Armstrong
