CLOGGED DRAINS
Other drain devices with small orifices
and poppet style valves are prone to clog
when solid debris is present. Each Drain-
All has a large, smooth liquid flow path
and discharge port as well as a heavy
duty shear action ball valve designed to
alleviate this problem.
ELECTRICITY
Timer valves require electricity. There is
a cost for installing and maintaining the
electric outlets they require as well an
ongoing operating cost of electricity year
after year. Drain-All requires no electric-
ity to operate since it is totally pneumatic
and can be easily installed at any point
along the compressed air system provid-
ing low cost installation and ongoing
operation.
RELIABILITY
Drain-All’s cycling is controlled by a
patented magnetic interaction with a
totally pneumatic control circuit. While
other pneumatic drains have a complex
lever action “toilet bowl” type internal
float with many parts, there are few mov-
ing parts in the Drain-All. Since the
Drain-All is totally pneumatic, it is not
affected by power outages or the other
vulnerabilities of electrical devices such
as timer solenoid valves, motorized ball
valves or electrically operated float traps.
BYPASSED DRAINS
Smaller drains become plugged so often
that cleaning them out becomes a very
labor intensive operation. To avoid con-
stant cleaning, there is a temptation to
bypass the inadequate drain and crack
open a manual bypass valve causing it to
drain constantly thus causing a constant
flow of wasted compressed air. Drain-
All’s anti-clog design eliminates the
temptation to bypass the drain.
SYSTEM BLOW DOWN
Manually operated drains, timer solenoid
valves, motorized ball valves or electri-
cally operated float traps blow away large
quantities of expensive compressed air.
Manually operated drains waste consid-
erable compressed air because most oper-
ators feel it is necessary to have the drain
open an extended period of time in order
to get all the liquid out. Timer valves are
almost always set to be open longer than
necessary in order to get all of the liquid
out and this also passes large quantities of
compressed air down the drain. Drain-
All avoids this waste of compressed air
and the resulting pressure drop in the
compressed air system by maintaining a
liquid seal in the bottom of the Drain-
All’s reservoir between each cycle.
AMOUNT OF LIQUID
Manual draining and timer valve draining
do not provide any information on the
quantity of liquid being produced in the
compressed air system.
Each Drain-All model discharges a spe-
cific amount of liquid on each cycle in a
given application. With the addition of a
Drain-All cycle counter on the Drain-All
unit, it is easy to track how much liquid is
produced over any period of time. This is
particularly important for benchmarking
system equipment performance and per-
forming trend analysis. For example, it is
essential to know the quantity of liquid
produced by a compressed air system to
properly size oil-water separators.
The counter coupled with a Drain-All
unit is an instrument. Once installed, it
provides tracking of the number of cycles
for periods of time at different ambient
temperature and humidity conditions.
This data can be plotted on a chart.
During operations thereafter, a check on
the number of cycles per time period of
actual operation compared to the chart
for a given temperature and humidity will
show if the correct amount of liquid is
being received by the Drain-All. Too
many cycles compared to the chart indi-
cates excessive liquid is being produced
somehow and should be investigated.
Too few cycles indicates that not enough
liquid is being produced and this too
should be investigated.
OVER-DRAINING
Manual drain valve operation and timer
valves are usually set for overkill in fre-
quency and duration of drainage times in
order to be certain that no liquid accumu-
lates in the system. This results in waste
of expensive compressed air. Drain-All is
demand activated and drains only when
the liquid reaches the predetermined trig-
ger point. The Drain-All does not over-
drain or blow down the system.
UNDER-DRAINING
Timer drains must be preset to establish
the frequency and duration of drainage.
The settings are vastly different in peri-
ods of high humidity from what they
would be in periods of low humidity. It is
common for this adjustment to be over-
looked in the transition from winter to
summer. Therefore, the settings are inad-
equate to handle the high summer quanti-
ties of liquid which results in excess liq-
uid accumulation in the compressed air
system. This liquid often backs up and
can cause damage to dryers, compressors
and hand tools that is expensive to repair.
The Drain-All is designed to cycle as
needed when liquid accumulates and
requires no adjustments from season to
season.
LIQUID REMOVAL
The air pressure in the system being
drained forces the liquid out of the Drain-
All reservoir. Because the power of the
air system is behind it, the discharge can
be directed upward, to a containment
vessel, oil-water separator or an overhead
discharge piping system.
