Compressed air dryers reduce the water vapor concentration and prevent water
formation in compressed air lines. Dryers are a necessary companion to filters,
aftercoolers, and automatic 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 the service life of pneumatic
equipment and tools, prevents air line freeze-ups, and reduces product rejects. The
use of dryers, aftercoolers, and filters is recommended when these moisture related
problems are reported to our factory or distributor service department.
