| Compact
Air Dryer |
|
The
compact air dryer series meets the needs of certain
low flow applications where very dry compressed
air is required, i.e., atmospheric dew point of
minus 50 °F or lower. Designed to minimize space,
the shoebox size unit is easily installed in tight
spaces.
The
self-regenerative air dryer can be operated continuously
at flow rates ranging from 0 - 0.5 scfm up to 0
- 6 scfm at minimum inlet pressures of 80 psig.

| Standard
Module |
| The
311C series air dryer is an insert module intended
to be installed within an enclosure. The unit
is a self-regenerative compressed air dryer which
removes water vapor continuously using a molecular
sieve desiccant material. Two stainless steel
tanks contain the desiccant. A timer, solenoid
valve and two flow control valves sequence the
air flow alternately through one tank and then
the other. A small amount of purge flow is discharged
continuously. A nominal dew point of -50°F
is achieved at maximum flow rate; even lower dew
point at less than maximum flow. Compressed air
supplied to the dryer should be clean (5 microns)
and oil-free. |

System |
|
Series
415 and 416 air dryer systems include the 311C
series dryer, and enclosure and two filters
completely assembled and ready for installation.
The filters have automatic drains for discharge
of collected liquids. Easily replaced filter
cartridges remove solids to 5 microns in the
first stage and liquids and solids to .03 microns
in the second stage.
Series
141/142 air dryer system has the unique feature
of not requiring electric power for operation.
Pneumatic timers and air operated relays are
used for automatic control of the self-regenerative
air dryer system. This pneumatic controlled
air dryer can be installed in compressed air
lines to decrease the dew point to -50°F.
A prefilter and coalescing filter both equipped
with automatic drains are standard components
of the system.

| High
Flow Module |
|
The
series 2042 and series 2043 high flow air dryers
will handle up to 20 scfm at supply pressure
of 80 to 125 psig. Using a solid state timer,
three power valves are sequenced to provide
the following features:
- Quiet
operation - No large pressure surge during
switching.
- Virtual
pulse free output pressure - No significant
pressure swing during switching.
- Three
models rated at 10, 15 and 20 scfm

| Point-of-Use
Dryer |
|
The
"point-of-use" compressed air dryer
removes liquid water using filters; and reduces
the pressure dew point of the air through pressure
reduction. The system consists of a prefilter
and a coalescing filter, followed by a pressure
regulator. Two gages and mounting hardware are
included in the system. Maximum flow rates of
10, 20 and 40 scfm are available as standard.
While
depression of dew point with the system is not
as dramatic as in desiccant air dryers, it is
an economical approach to solving local in-plant
air line water problems.

| Accumulators |
|
Compressed
air accumulators serve to reduce or eliminate
pulsation which occurs twice in each cycle of
twin tower, self-regenerative compressed air
dryers. The accumulators are complete with an
inlet check valve, a 125 psig relief valve,
and an output pressure regulator.
The
portable 20 gallon unit can also be used as
a storage tank for clean, dry compressed air.
Usable for low flow requirements at a remote
location that does not have a compressed air
source.
