4.6.1.1 Option da
Compressed-air aftercooler
The aftercooler lowers the compressed air temperature to only 9°F to 18°F above ambient. Most of
the moisture carried in the air is removed this way in the aftercooler.
4.6.1.2 Option da
Compressed air water separator
Condensate accumulating during the air cooling process is separated, fed to the exhaust gas si‐
lencer and evaporated there.
4.6.1.3 Option db
Heat exchanger
The oil/air heat exchanger is fed with hot compressor cooling oil that warms the outgoing moisture-
reduced compressed air.
This warm, dry compressed air is ideal for sand blasting, for example.
4.6.1.4 Option ea
Tool lubricator
Compressed air containing lubricating oil is needed for the lubrication of certain air tools. The tool
lubricator introduces a fine oil mist into the compressed air for this purpose.
The amount of oil in the compressed air is controlled by a metering valve on the lubricator:
■ minimal oil to lubricate the tools and prevent corrosion,
■ more oil for cleaning and to prevent wear in the tools.
The oil flow can be cut off completely by a shut-off valve.
The oil flow adjusts automatically to changes in air demand (one or more tools/consumers on line).
