Principles of Cooling Systems
These compressors are equipped with a compressor sheave with fan blades.
The fan blades force ambient air across cylinder head and intercooler fins to
cool the compressor. These compressors are designed to be operated with the
compressor sheave turning in a counterclockwise rotation (as viewed “tummy
to the sheave”).
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.
