Dryers And Filters - Curtis CT Series Instruction Manual

CT SERIES
RECOMMENDED STATEMENT ON DRYERS AND FILTERS
Liquid water occurs naturally in air-lines as a result of compression. Moisture
vapor in ambient air is concentrated when pressurized and condenses when cooled in
downstream air piping.
Compressed air dryers reduce water vapor concentration and prevent liquid
water formation in compressed air lines. Dryers are necessary companion to air filters,
aftercoolers, and automatic tank drains for improving the productivity of compressed air
systems.
Water and water vapor removal increases the efficiency of air operated
equipment, reduces contamination and rusting, increases service life of pneumatic
equipment and tools, prevents air line freeze ups, and reduces product rejects. The use
of dryer's filters is recommended when this moisture related problems are reported to
our factory or distributor service departments.

Problem:
Solution:
Liquid water present in compressed air-lines.
Water vapor condensation from cooling and
compression occurs naturally
Remove the water vapor from compressed air prior to
distribution through the air system. Check operation of
after-cooler and moisture separator. Install a compressed
air dryer sized for the flow and dryness level required.
(Note: filters may also be required to remove
particles, liquid oil aerosols, or for oil vapor removal.
Change cartridges as recommended by filter manufacturer.)
Check all drain traps routinely to insure their proper operation.
Maintain them regularly.
