Sullair SD Series Dryers provide clean, dry air
by removing the water.
The result: corrosion and
damage are eliminated.
• Productivity improves and maintenance costs are reduced.
• The service life of air tools, motors and cylinders is extended.
• The life of your entire compressed air system is prolonged.
The benefits of Sullair SD
Regenerative Dryers:
Clean, dry compressed air
Sullair SD dryers use desiccant material to adsorb water vapor from compressed
air. By combining the proven benefits of desiccant drying with the most advanced
designs, Sullair offers an extremely compact, reliable system to clean and dry compressed
air for the most critical applications.
These regenerative dryers are ideal for processes that require an extremely low
dew point to -40°F (-40°C) as standard and optional -100°F (-77°C).
Reliable operation.
Simple circuit design, minimal moving parts plus quality manufacturing and
materials assure long, trouble-free service life.
Standard features
• Activated alumina desiccant
with superior adsorption
capacity.
• Proven, compact valves on
models SD-220 to SD-600
operate using minimal
moving parts.
• Three-way plug and angle seated
valves on SD-820 to
SD-3400 for inlet air
switching and purge exhaust
control.
• Purge control regulates purge
flow in relation to dry air
output.
• Repressurization circuit with
PLC controls for added
reliability.
• Desiccant towers are ASME
code stamped and CRN
approved.
Designed for sub-freezing
temperatures.
These regenerative dryers are ideal
for installations with outdoor
compressed air piping, and for
processes that require an extremely
low dew point to -40°F (-40°C) as
standard and optional -100°F (-77°C).

The SD dryers range
in capacity from 220 to 3400 scfm
(6.3 to 96.3 m3/min).
Easy installation.
The SD dryers are packaged and
ready to pipe up.
Sullair
recommends using a Sullair
coalescing filter upstream to assure
long desiccant life and a Sullair
particulate filter downstream to
catch desiccant carryover.
Optional feature.
Energy-saving dew point dependent
switching.
