Data Sheet

Manufacturing and process plants use
compressed air as a power supply for many
devices within the plant. Plant air, also called
shop air, is used for cooling and as a power
source for pneumatic tools, sand blasters,
sprayers, conveyors, robotics, and other
mechanical tools. Instrument air is used to
power instruments, such as controllers,
positioners, switching valves, panel loaders,
and volume boosters.
Plant air or shop air runs from compressor
throughout the plant. Pressure reducing
regulators control the pressure to devices at
each point of use of the air line.
Instrument air can come from the plant air line,
or they may be separate air lines throughout
the plant. In either case, the air supplied to the
instruments must be cleaned and dried before
it enters the instruments. Filters and dryers
remove dust, moisture, and other debris from
the air.
