Do not operate the dryer until the instructions in this manual have been read and understood by
all personnel concerned.
When handling, installing or operating, personnel must employ safe engineering practices and observe all
related regulations, health and safety procedures, and legal requirements for safety.
Most accidents that occur during the operation and maintenance of machinery are the result of failure to
observe basic safety rules and procedures. Accidents can be avoided by recognising that any machinery
is potentially hazardous.
Sullair can not anticipate every possible circumstance which may represent a potential hazard. The
WARNINGS in this manual cover the most known potential hazards, but by definition cannot be all
inclusive. If the dryer user employs an operating procedure, item of equipment or a method of working
which is not specifically recommended by Sullair the user must ensure that the dryer will not be damaged
or made a potential hazard to persons or property.

The SAR range of compressed air dryers are designed to remove moisture from compressed air by
utilising state of the art technology to obtain pressure dewpoints of -40
o
C / -40
o
F, and by appropriate
de-rating, -70
o
C / -94
o
F.
The SAR range of dryers have been designed to require minimal maintenance and can be installed
virtually anywhere.
The SAR dryer consists of an inlet and an outlet manifold joined together with an aluminium column. The
column has twin internal chambers both filled with desiccant material. During operation one chamber is
on-line (drying) while the other is regenerating, using the Pressure Swing Adsorption (PSA) process.
Pressure Swing Adsorption (PSA)
A small percentage of dried air is taken from the dryer output flow and is used to regenerate the saturated
chamber by expanding the dried air from line pressure to atmospheric pressure. During this process, the
moisture is physically removed from the regenerating chamber and vented to atmosphere through the
exhaust silencers.
Dewpoint Dependent Switching (DDS) - Optional
If DDS is fitted, this will adjust the dryers cycle in line with the moisture loading placed upon it, by
constantly monitoring the processed air moisture content. Also available as a retrofit to all SAR dryer
models.
