Installation, Operation & Maintenance Data
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:
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.
pipe cuttings, scale, and dirt. Last of
all, screw the trap into position.
Aftercoolers to bring the compressed
air down to ambient or room
temperature.
2.
Separators to knock down suspend-
ed droplets of water or fog.
First install piping and shut-off
valve ahead of trap, then blow down
the line at full pressure to remove
A
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.
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.

TRAP INSPECTION
AND MAINTENANCE
1. Check trap operation periodically.
Determine that body is full of water
(trap is primed).
2.
If examination shows heavy coating

of oil on mechanism, arrange to clean
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

*Capacity - 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.

OPERATING SEQUENCE OF
ARMSTRONG NO. 800 BVSW SERIES INVERTED BUCKET AIR TRAPS
1. Trap connected to unit to
be drained. Bucket is
down, and the trap valve
is wide open. Before
placing in service,-
the trao.
4. Air has collected at top
of trap, and water level
has r i s e n in bucket to
make it heavy enough to
2. Trap can be primed
through prim in g plug in
cap.

5. Sink and open discharge
valve. First air, next oil,
and then any extra water
is discharged. Air dis-
places water from bucket
which again floats and
closes valve, and the
condition shown in Fig. 3
again will prevail,
3. When inlet valve is open-
ed, air pressure forces out
extra water and displaces
enough w ate rinside the
bucket to make it float
and close the valve. Air
bleeds through bucket
vent. Additional water is
coming to the trap.
