enclosure, across the motor, compressor and intercooler. These compressors are
designed to be operated with the compressor sheave turning in a counterclock-
wise rotation (as viewed “tummy to the sheave”). QT, PLT and Xtreme
compressors should be operated in temperatures under 104°F.
Principles of Dryers & Filters
Moisture 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 the moisture
vapor concentration and prevent water formation in compressed air lines.
Dryers are a recommended companion to filters, aftercoolers, and automatic
drains for improving the productivity of compressed air systems.
Water and moisture 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.
