Accessories
Every compressor may be modified or
expanded by the manufacturer (if requested in
the order) or by subsequently ordering
accessories, see below. The individual
accessories may be combined.
Accessories are not included in the
standard order and must be ordered
separately!
7.3.1. Set of compressed air outlet
filters
Compressor may be equipped with a set of
filters if specified. The set of filters may be
equipped with a pressure regulator. Sets of
filters are suitable accessories for all the
compressors specified above.
If a different level of air filtration is
required, this specification must be
agreed upon with the supplier and
specified in the order

8. PRODUCT FUNCTIONALITY
The compressor produces oil-free, dry, filtered
compressed air to power pneumatic devices
and equipment used in large dental clinics and
laboratories, hospital wards, etc.
Compressor air pumps (1) draw in
atmospheric air through the inlet filters (8) and
compress it through a check valve (3) and into
the common outlet manifold from the air
pumps (19). From there, the compressed air
proceeds to the cooler (10), in which the
compressed air is cooled for the first time and
condensate is produced. The air then passes
through a water separator (13) and into the
condensing dryer (11). This continues to lower
the temperature of the air and produces more
condensate. The temperature then rises to
reduce the relative humidity. The clean, dry air
then passes through a check valve (18) and
enters the air tank (2). Condensate from the
water separator and the dryer is drained off
into a 10 l vessel (14) in the condensate drain
kit. The dryer ensures continuous and no-loss
drying of the compressed air. Treated
compressed air is then ready for additional
use in the air tank.
Check the dryer (11) and the air tank check
valve (18) to ensure they are operating
properly if the pressure relief valve (12)
continues to open.
Adjusting the opening pressure of
the pressure relief valve or other
modification of this valve is
prohibited!
