SECTION 1 – GENERAL
Scope of Manual
This instruction manual is intended to assist our customers with the installation,
operation, and maintenance of their PUREGAS compressed air dryer or adsorber. The
information contained in this manual is designed to ensure a productive, trouble-free
ownership experience and should be retained for future reference.
Initial Inspection
PUREGAS products are produced in a lean manufacturing environment, where quality
assurance practices are built into all processes. Moreover, all products are thoroughly
inspected and tested prior to shipment. If shipping damage is noted, immediately
contact the responsible carrier to file a freight claim to cover the repair.
Warranty
Please read this instruction manual carefully prior to installing and operating your
PUREGAS product. Failure to follow these instructions could lead to potential safety
concerns and may void the warranty. The warranty agreement can be found on the
inside cover of this instruction manual.
SECTION 2 – DESCRIPTION OF OPERATION
General Description
PUREGAS compressed air dryers and adsorber are used to separate various elements
in compressed air using Pressure Swing Adsorption (PSA) technology. This method
employs two identical desiccant chambers, precision orifices, and solenoid valves
controlled by a solid state electronic timer.
The process is simple. The compressed air is directed through a desiccant chamber,
which contains an adsorbent material with strong affinity for moisture, CO
2
, and/or other
elements within the air stream. Once purified, the majority of the compressed air goes
directly to the application, while a portion is diverted through an orifice to regenerate the
off-line chamber. The solid state timer reverses the flow through the chambers on a
timed cycle by opening and closing the solenoid valves.
Applications
As described above, PUREGAS compressed air dryers and adsorbers are typically
used to purify a compressed air source. They may, however, be used with inert gases
(nitrogen, argon, neon, helium, and carbon dioxide), as well as other common gases
with certain restrictions. For example, oxygen requires a completely oil-free system and
hydrogen (being explosive) should be handled with explosion-proof equipment.
