4.7.1.4 Option dd
Filter combination
The dried compressed air passes through a pre-filter and micro-filter combination and emerges oil-
free.
4.7.1.5 Option dc
Fresh air filter
Compressed air from oil-injected compressors may not be used directly as breathing air.
The concentration of contaminants will increase during the compression of the intake ambient air
and cooling oil and abraded particles can enter the compressed air. This requires a subsequent
treatment of the pre-filtered compressed air.
Air must be filtered to remove all contaminants, such as fine dust and oil as well as odors, before it
can be used for breathing purposes.
To achieve this, part of the compressed air output from the compressor is passed through a combi‐
nation of micro-filter and activated carbon filter.
The connection to air treated in this way is specially marked. It is designed as a quick-release cou‐
pling next to the outlet valves on the compressed air distributor.
Danger from toxic air!
Danger of respiratory arrest because the filter does not remove CO/CO
2
, methane or other
toxic gasses or vapors.
➤ Never use the machine in enclosed spaces, only in the open.
➤ Clean inlet air without hazardous contaminants. Engine exhaust must not be drawn into
the compressor.
The treated air does not meet the local standards for “Compressed air for breathing appara‐
tus”. Therefore, it must not be used as pure breathing air but may be used to reinforce the
flow of fresh air when working in dusty or dirty conditions such as sand blasting.
Further information See chapter 2.7.1.2 for ambient conditions under which the fresh air filter can be used.
Further information See DIN EN 12021 for more information regarding permissible limit values for hazardous contami‐
nants in breathing air.
4.7.1.6 Option ea, ec
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.
A metering valve on the lubricator regulates the amount of oil in the compressed air:
■ minimum oil to lubricate the tools and prevent corrosion,
■ more oil for cleaning and to prevent wear in the tools.
The oil flow can be stopped by a shut-off valve.
The oil flow adjusts automatically to changes in air demand (one or more tools/consumers on line).
