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-

DRAIN-ALL SOLVES PROBLEMS

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.
